  • Ocular Hypotonia and Transient Decrease of Vision as a Consequence of
           Exposure to a Common Toad Poison

    • Abstract: The common toad produces venom (bufotoxin) that is produced in the parotid gland of the toad as well as in the skin. This toxic compound is a potent inhibitor of Na+/K+-ATPase activity. Physiological effects of bufotoxin are similar to those of digitalis and cause increased heart rate and muscle contractions. Ocular toxicity was described. A 67-year-old female patient was admitted to the emergency service because of sudden vision loss and a burning sensation in both eyes after she had been exposed to the poison of a toad. Slit lamp examination showed conjunctival hyperaemia and signs of ocular hypotonia. Topical antibiotic treatment was administered, and after 24 hours, corneal oedema and ocular hypotonia were in remission. Inhibition of Na+/K+-ATPase is a well-known effect of the toad venom. Na+/K+-ATPase is a part of corneal endothelial cells, ciliary body, and iris, and its inhibition caused by exposure to bufadienolides induces corneal dysfunction, decreased vision, and ocular hypotonia. Effects of bufadienolides on the decrease of ocular pressure appear to be very strong, with quick action. This rarely described effect of the bufotoxin can be used as a basis for further research of toad venom and its pharmacological potential. Purpose. To present a case of a 67-year-old female patient who experienced a sudden decrease in vision after exposure to the poison from a common toad (Bufo bufo).

  • A Rare Presentation of Orbital Castleman’s Disease

    • Abstract: Castleman’s disease (CD) is an uncommon group of atypical lymphoproliferative disorders. Extranodal involvement such as the orbit is extremely rare. We aim to report a case of a 62-year-old male who presented with left painless proptosis for the past three years. Examination revealed a firm, lobulated mass in the left superotemporal orbit, displacing the globe inferomedially. A well-defined extraconal orbital lesion encasing the left lateral rectus muscle with intraconal extension was seen on Magnetic Resonance Imaging (MRI) that led to the provisional diagnosis of left solitary encapsulated venous malformation. Excision of the mass via lateral orbitotomy was performed. However, on histopathology, the features were consistent with a mixed-cell variant of Castleman’s disease. A detailed systemic workup was unremarkable. Proptosis resolved after surgery and no recurrence was noted in the three-year follow-up. To the best of our knowledge, this is the first case report of a mixed-cell variant of unicentric orbital CD without any systemic features. This case highlights the importance of including CD in the differential diagnosis of well-defined orbital lesions so as to enable its early detection and timely management.

  • Large Orbital Pediatric Intraosseous Hemangioma

    • Abstract: A five-year-old male presenting with progressive right facial swelling underwent multiple biopsies before being diagnosed with a polyostotic frontal-zygomatic primary intraosseous hemangioma. Intraosseous hemangiomas are rare, more frequently afflict adult females, and very rarely involve the orbit. Our case with bony destruction and surrounding soft tissue mass measured 5.3 cm in a child mimicked a more ominous malignancy. This case is unique with its rapid progression and largest reported size, leading to additional challenges such as difficulty in achieving an adequate tissue sample and in the surgical management with respect to significant blood loss in a small child.

  • Induced Myopia Secondary to Blunt Trauma

    • Abstract: A 28-year-old young man presented with sudden and severe visual loss in the left eye, starting three days ago following blunt head trauma from a closed fist. Vision was not improved to better than 0.4 in the left eye. Slit lamp examinations revealed asymmetric anterior chamber depth (ACD) with shallow ACD in the left eye. The key learning in this report is the use of anterior segment optical coherence tomography (AS-OCT) to better document the anterior segment changes following the blunt trauma. AS-OCT was used to visualize the forward displacement of the iris-crystalline lens diaphragm secondary to ciliary body anterior rotation and ciliochoroidal effusion. There was a temporary myopic shift about 7.00 D which resolved after 15 days.

  • No Severe Adverse Effects from Intravitreally Injected Putative Adipose
           Tissue-Derived Stem Cells

    • Abstract: This study reports findings from a 56-year-old patient, who had received bilateral intravitreal injection of putative adipose tissue-derived stem cells at a private clinic in India with the promise of treatment of NAION. During an observation period of 8, respectively, 18 months, the intravitreally injected cells remained silent in the vitreous bodies without either therapeutic effects or complications. The cells cleared with vitrectomy without evidence of integration in the optic nerve or retina. Contrary to recent reports on patients receiving intravitreal injections of similar putative stem cells with the aim of treating AMD, our patient suffered no devastating ocular consequences. Summary. Contrary to recent reports, this case demonstrated no devastating consequences of intravitreal injection of adipose tissue-derived stem cells during an observation period of up to 18 months. After vitrectomy, the cells cleared without evidence of either harm or integration.

  • Hyperbaric Oxygen Therapy in Retinal Arterial Occlusion: Epidemiology,
           Clinical Approach, and Visual Outcomes

    • Abstract: Purpose. To evaluate the efficacy and safety of hyperbaric oxygen therapy (HBOT) in patients with acute retinal artery occlusion (RAO). Secondarily, to analyse the epidemiology and the clinical approach. Methods. Retrospective study of 13 patients submitted to HBOT between 2013 and 2018. The analysed parameters consisted of: systemic history, time between symptoms onset and treatment, initial approach, number of HBOT sessions, complications of HBOT and best corrected visual acuity—BCVA (of the total sample, central RAO—CRAO—group, and branch RAO—BRAO group). Results. Arterial hypertension was the most prevalent systemic risk factor (53.8%). Initial therapies were 100% normobaric oxygen administration, topical and oral hypotensive medication, eye massage and aspirin. CRAO was observed in 69.2% and BRAO in 30.8% of the cases, with clinically significant visual improvement (a decrease in logMAR of 0.3) in 55.5% and 75%, respectively. Time between symptoms onset and treatment had a median of 9 hours. The median number of HBOT sessions was 7, without complications. Conclusions. HBOT provide BCVA improvement in patients with RAO, when it is performed in an early time after the symptom onset. It seems to be an effective and safe therapeutic option for a pathology that still remains without approved treatment.

  • Fundoscopic Changes in Maroteaux-Lamy Syndrome

    • Abstract: Purpose. To describe a clinical case of mucopolysaccharidosis type VI (MPS VI), or Maroteaux-Lamy syndrome, with fundoscopic alterations that may correspond to scleral deposits of glycosaminoglycans. Materials and Methods. Clinical case report. Results. A 16-year-old girl with MPS VI was examined at the Ophthalmology Department for poor vision due to opacified corneas. Treatment consisted of bilateral penetrating keratoplasty. Retinographies and enhanced depth imaging optical coherence tomography (EDI-OCT) were performed after surgery, suggesting the presence of scleral glycosaminoglycan deposits. The patient evolved with stable corneal and fundoscopic findings. Conclusions. To our knowledge, this is the first case of MPS VI described in vivo with suspected deposits of glycosaminoglycans in the sclera. Fundoscopic alterations are not usually included in the ocular pathological spectrum of MPS VI. However, with improved control of systemic comorbidities, survival rates of these patients have increased, which in turn has made it possible to observe other changes besides the ones that were classically described. Despite being particularly challenging to manage, efforts should be made to maximizing the visual acuity of these patients, in order to provide them the best possible quality of life.

  • Congenital Microphthalmia with Intraorbital Cyst: A Rare Case Report

    • Abstract: Microphthalmia is considered to be the most common congenital malformation of the eye after congenital cataract. However, its association with intraorbital cyst is considered to be very rare. Most of the lesions are still misdiagnosed as orbital tumor and teratomas as there is a general paucity of data reported in literature. Herein, we report a rare case of congenital microphthalmia with intraorbital cyst in an eight-month-old male patient.

    • Abstract: Focal choroidal excavation (FCE) is an unusual configuration characterized by focal thinning and pitting of the choroid in the absence of staphyloma or scleral ectasia. The etiology and clinical implications of FCE are currently unknown. We report a case of bilateral multiple FCEs in a patient with a long history of paroxysmal nocturnal hemoglobinuria (PNH). Focal choriocapillaris thinning and hyperreflectivity of the adjacent outer nuclear layer were revealed by spectral domain optical coherence tomography, which suggests the occlusion of the choriocapillaries and secondary degeneration of the above photoreceptors. We hypothesize that thrombophilia in the condition of PNH played an important role in the formation of FCE. Although there is no histopathological evidence to support the association between the choroid changes and PNH, this case may offer new clues as for the etiology of FCE.

  • Rhino-Orbito-Cerebral Mucormycosis: Two Cases with Amaurosis as
           Presentation, Medical Surgical Management and Follow-Up

    • Abstract: Purpose: Mucormycosis is an infection caused by fungi to the class Zygomycetes that usually appears in immunosuppressed patients. Diagnostic confirmation is often delayed, with fatal prognosis in cases in which treatment is not rapidly established. Case report: We present two clinical cases of rhino-orbito-cerebral mucormycosis with an atypical presentation form, consisting of a unilateral complete sudden vision loss. Intravenous treatment with liposomal amphotericin B was started and total orbital exenteration surgery was performed. The removed surgical area was filled with gauze impregnated with liposomal amphotericin B and was left open for cures every 12 hours. Due to the good clinical evolution, a reconstruction of the orbital exenteration defect was performed in Case 1 with a temporal muscle flap and a skin island pedicled flap. In Case 2, reconstruction was not performed due to the poor evolution of the patient. Discussion: As it is a very aggressive surgery, the aesthetic and functional sequelae are very important. When the survival of the patient is achieved, we should offer reconstructive solutions that improve their quality of life. The reconstruction carried out using a flap of the temporal muscle can be made in a single act without requiring microvascular surgery.

  • En Face Optical Coherence Tomography Imaging Ellipsoid Zone Regeneration
           in Laser-Induced and Solar Maculopathies

    • Abstract: The purpose of the study was to analyze imaging findings in spectral domain en face optical coherence tomography (SD OCT) in patients with laser‐induced and solar maculopathies focusing on the possible regeneration of the ellipsoid zone. In a retrospective case series of 3 patients (4 eyes) with solar maculopathy and 2 patients (3 eyes) with laser‐induced maculopathy who underwent a comprehensive ocular examination, ellipsoid zone (EZ) was segmented from SD OCT data. Evaluation of EZ in en face OCT revealed a hyporeflective lesion surrounded by a hyperreflective border. The area of EZ alteration was measured manually in en face OCT. All patients showed partial EZ regeneration. Mean EZ alteration decreased from 0.12 mm2 (range: 0.05–0.32) at baseline to 0.07 mm2 (range: 0.01–0.22) at last follow‐up (, mean follow‐up: 372 days; range: 115–592). Mean best visual acuity (BVA) improved from 20/36 at baseline to 20/30 (). In conclusion, en face OCT imaging clearly delineated the area of EZ alteration in patients with laser‐induced and solar maculopathies. Follow-up showed significant reformation of the EZ as well as improvement of BVA.

  • Autologous Platelet-Rich Fibrin in the Treatment of Refractory Macular
           Holes

    • Abstract: Purpose. To describe a novel method for the treatment of refractory macular holes. Methods. Two case reports on the use of autologous platelet rich fibrin (PRF), followed by sulfur hexafluoride gas tamponade to facilitate closure of refractory macular holes. Results. Macular holes were succesfully closed within a week in both cases. Best corrected Snellen visual acuities improved from counting fingers to 0.16 in the first case, and from 0.05 to 0.2 in the second case. No complication occurred during or after the procedures. Conclusion. The use of autologous PRF seems to be a safe and effective alternative method for the treatment of refractory macular holes. Further experience and studies are required to assess the value of autologous PRF in the management of challenging macular hole cases of different etiologies. To the best of our knowledge, this is the first use of autologous PRF in the treatment of macular holes.

  • Giant Squamous Cell Papilloma of the Eyelid—Diagnostic and
           Therapeutic Challenges

    • Abstract: Squamous cell papilloma (SCP) is generally a human papillomavirus (HPV) induced exophytic or endophytic proliferation on the surface of the skin, oral cavity, larynx, esophagus, cervix, vagina, and anal canal. The endophytic type SCP can cause differential diagnostic difficulties with keratoacanthoma, inverted follicular keratosis, and squamous cell carcinoma; however, these lesions are not associated with HPV infection. The authors present a female patient who noticed an extremely rapidly growing tumor destructing the left lower eyelid. The histological analysis of the biopsy sample revealed a virus-induced squamoproliferative lesion. The eyelid affected was completely removed, and the histological examination resulted in a HPV induced endophytic squamous cell papilloma. The tarsus and the conjunctiva were replaced by a chondromucosal graft harvested from the nasal septum, while the skin defect could be closed directly. Restoration of the eyelid function has been achieved with satisfying functional and cosmetic results.

  • Contralateral Posterior Chamber Phakic Intraocular Lens Implantation as
           Rehabilitation of Refractive Lens Exchange with a Monofocal Intraocular
           Lens in a Young, Nonpresbyopic, Bilateral Highly-Myopic Patient

    • Abstract: Background. Refractive errors are widespread in the human population; nowadays, numerous surgical options allow for efficient and safe correction them. One of the main elements to ensure success in this kind of intervention will depend on the careful patient and surgical approach selection. Excimer laser corneal surgery is considered by most for low to moderate ametropias. Another option, which has been suggested may be safer, is to cut a small corneal lenticule with femtosecond laser, and then extracting it through a small incision. Nevertheless, in some specific cases, such as patients with high refractive error or those with some corneal abnormality, laser corneal ablations are considered unsafe from either a biomechanical or refractive standpoint. In this kind of particular cases, Phakic Intraocular Lens (P-IOL) implantation constitutes attractive, highly predictable and safe option. Objective. The authors want to show the case of a young high-myopic woman, already pseudophakic in one eye, where the P-IOL implantation in the fellow eye yielded excellent short-term visual results, and high patient’s satisfaction, is presented. Materials. The authors present the case of a 32-years-old, highly myopic female patient underwent a Refractive Lens Exchange (RLE) with a monofocal Intraocular Lens (IOL) implantation in her left eye elsewhere, and developed severe visual issues, especially regarding near-work. Symptoms resolved through the implantation of a posterior chamber P-IOL in the contralateral eye. Results. The postoperative course was unremarkable, inflammation was mild, and visual recovery was quick. There was no need to perform any procedure on her left eye or to use any reading glasses, as unilateral effective near vision through her right eye was enough for all her daily tasks. Conclusions. RLE in young pre-presbyopic highly myopic patients may not be an advisable alternative in most cases, because of the high risks of retinal complications observed. In addition, eliminating accommodation will cause significant limitations, and multifocal IOLs currently available are far from the quality of vision that a young human crystalline lens yields. On the other hand, implantation of a P-IOL is a good option if eye conditions are optimal, as it preserves natural accommodation. In this case an EyeCryl Phakic Toric® IOL showed excellent short-term refractive predictability and safety.

  • A Case Report Illustrating the Postoperative Course of Descemetorhexis
           without Endothelial Keratoplasty with Topical Netarsudil Therapy

    • Abstract: Fuchs endothelial corneal dystrophy (FECD) is the most common indication for corneal transplantation in the United States. Recently, descemetorhexis without endothelial keratoplasty (DWEK) or Descemet’s stripping only (DSO) has become an attractive alternative to corneal transplantation for these patients. DSO circumvents the challenges associated with cadaveric donor corneal transplantation by tapping into the potential of the patient’s own corneal endothelium to repair defects. Outcomes have been variable with emerging knowledge on predictive factors for success. Our case describes a 51-year-old patient with visually significant confluent central guttae from FECD who underwent a successful DSO with immediate post-operative use of the Rho-associated protein kinase (ROCK) inhibitor (netarsudil). We report the preoperative and post-operative slit lamp images, specular microscopy data, and corneal topography, thickness, and densitometry data. These represent a unique data set for this new surgical treatment option for FECD. Despite a small descemetorhexis, we show the improvement in corneal thickness and opacity extends beyond the boundaries of the descemetorhexis. Early initiation of a ROCK inhibitor was a successful treatment for this patient.

  • Nontraumatic Epithelial Ingrowth 15 Years Post Laser In Situ
           Keratomileusis

    • Abstract: Purpose. Epithelial ingrowth occurring many years after primary Laser in Situ Keratomileusis (LASIK) without a preceding traumatic event is very rare. Case Report. We describe the case of a 61-year-old woman with epithelial ingrowth in her right eye 15 years after primary LASIK. She presented with right eye redness, pain, and decreased vision and denied any preceding trauma. An epithelial cells’ tract was visible on Optical Coherence Tomography. Conservative treatment lead to the stabilization of the epithelial nests. Discussion. Epithelial ingrowth can occur many years after LASIK and may be due to a microtrauma to the edge of the flap.

  • A Case of Unilateral Coccidioidal Chorioretinitis in a Patient with
           HIV-Associated Meningoencephalitis

    • Abstract: Intraocular coccidioidomycosis is a rare condition, with the most commonly reported presentation being an idiopathic iritis in patients who live in or have traveled thorough endemic areas. A paucity of reports exists describing the chorioretinal manifestations of coccidioidomycosis. Here we report a case of unilateral coccidioidal chorioretinitis and meningoencephalitis in an AIDS patient that led to near complete unilateral loss of vision. A 48-year-old Hispanic female with poorly controlled HIV/AIDS in southern California presented with a three-week history of headache, nausea, vomiting, right eye blurry vision, and a one-day history of subjective fever. Examination of the right eye revealed vitritis and several large chorioretinal lesions scattered throughout the periphery and macula with optic disc pallor. Serum coccidioidomycoses complement fixation (CF) was positive (titers of 1 : 256). Neuroimaging revealed a new area of enhancement in the left anterior frontal lobe consistent with meningoencephalitis. The patient was treated with intravenous fluconazole and intravitreal voriconazole with resolution of systemic symptoms and vitritis but persistence of unilateral, severe chorioretinal scarring and vision loss. In conclusion, in spite of the rarity of intraocular coccidioidomycosis, one must carry a degree of suspicion for this vision- and life-threatening condition as a potential etiology of chorioretinitis in individuals with pertinent risk factors.

  • Bilateral Retinal Angiomatous Proliferation in a Variant of Retinitis
           Pigmentosa

    • Abstract: Purpose. To describe the first case of bilateral retinal angiomatous proliferation (RAP) in a patient with a variant of retinitis pigmentosa (RP). Case Report. An 85-year-old man with RP presented with visual acuity decrease and metamorphopsia in the left eye (LE). Fundus examination revealed typical signs of RP in both eyes, associated with intraretinal macular hemorrhage in the LE. Multimodal imaging, using Colour fundus Photography, Fluorescein (FA), and Indocyanine Green Angiography (ICGA) as well as Spectral-Domain Optical Coherence Tomography (SD-OCT) and Optical Coherence Tomography Angiography (OCTA), revealed a type 3 neovascular lesion in the involved eye. Genetic testing (NGS analysis) was performed to search for genetic variants correlated with the disease phenotype displayed by the patient. The patient was treated with intravitreal injections of bevacizumab, according to a fixed protocol of bimonthly injections plus a booster dose at second month. After 9 months, he was referred for visual acuity decrease and metamorphopsia in the fellow eye, where SD-OCT/OCTA showed a type 3 neovascular lesion in the right eye (RE). He was scheduled for intravitreal injections of bevacizumab. In both eyes, treatment with intravitreal bevacizumab was successful.

  • Bilateral Anterior and Intermediate Uveitis with Occlusive Vasculitis as
           Sole Manifestation of Relapse in Multiple Sclerosis

    • Abstract: 76-year-old female patient, with past medical history of relapsing-remitting multiple sclerosis manifested by retrobulbar optic neuritis in both eyes with an interval of one year between the first episode in the left eye and the one in the right eye and after three decades of remission, who consulted due to bilateral blurred and foggy vision. Subsequently, several differential diagnoses where ruled out. Diagnosis of bilateral anterior and intermediate uveitis with occlusive vasculitis attributed to a new relapse episode of multiple sclerosis was made, as the association between multiple sclerosis and intermediate uveitis is known, though the causal association is still questioned. This case shows how multiple sclerosis may only manifest with ocular involvement and exemplifies the broad spectrum of manifestations and complications, taking into account that ischemic areas from vasculitis and other comorbidities led to macular edema and unfortunately, prognosis became poorer. The complex course of the case enables emphasizing the responsibility role of the ophthalmologists in such systemic entities that may compromise the eye, in which suspicion of the disease and an adequate timing management approach is essential.

  • IgG4-Related Ophthalmic Disease Presenting as Meningitis and Panuveitis

    • Abstract: Purpose. We report an uncommon case of immunoglobulin gamma 4-related ophthalmic disease (IgG4-ROD) presenting as meningitis and panuveitis. Observations. A 35-year-old male with no prior ophthalmic history presented with headaches, altered mental status, and fever of unknown origin. A lumbar puncture (LP) revealed an elevated white count with lymphocytic predominance, confirming a suspected meningitis. After an extensive work-up, he was discharged on oral acyclovir to cover for presumed aseptic meningitis. The patient initially improved, however, bilateral eye pain, redness, and photophobia 2 weeks after discharge prompted his first visit to the ophthalmology clinic. Exam at that time was consistent with bilateral anterior uveitis for which he was given topical prednisolone and cyclopentolate. In addition to the preceding work-up, quantitative immunoglobulin serology including IgG4 levels was added. At follow-up, he was found to have increased ocular inflammation with vitreitis, nerve head edema, and subclinical macular thickening. Visual acuity (VA) had decreased in both eyes. Serology titers for IgG had resulted in a significant elevation in IgG subclass 4 (IgG4). Optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) confirmed posterior retinal involvement. The patient was diagnosed with presumed bilateral panuveitis secondary to IgG4-ROD. Conclusions and Importance. IgG4-RD can be a serious condition that requires careful consideration and intuition to diagnose. This report serves to encourage ophthalmologists to consider IgG4-ROD in cases of idiopathic systemic inflammation with ophthalmic involvement.

  • Acute Posterior Multifocal Placoid Pigment Epitheliopathy Sharing
           Characteristic OCT Findings of Vogt-Koyanagi-Harada Disease

    • Abstract: A 17-year-old male presented with acute bilateral paracentral scotomata and blurred vision. Funduscopic examination showed bilateral macular serous retinal detachment and yellow-white placoid lesions at the level of retinal pigment epithelium. OCT study showed typical VKH disease findings with marked choroidal thickening and macular serous retinal detachment partly with subretinal septa in both eyes. FA demonstrated hypofluorescence at the placoid lesions in the early phase and hyperfluorescence in the late phase. Laboratory investigation showed negative result for HLA-DR4 serotype and the patient’s cerebrospinal fluid test values were within normal range. We made the diagnosis of APMPPE from these results. At 2-month follow-up without the use of corticosteroids, OCT reexamination showed complete amelioration of subretinal fluid in both eyes. Patchy pigmentary lesions also resolved clinically with partial chorioretinal scars. The results in this case suggested OCT findings in APMPPE patients could be similar to characteristic features usually found in acute VKH disease. We recommend comprehensive assessments such as FA, cerebral spinal fluid analysis, and HLA typing which help in leading proper diagnosis.

  • Optical Coherence Tomography Angiography (OCT-A) in a Patient with Occult
           Retinal Dysfunction

    • Abstract: Multimodal imaging techniques were performed in a patient with a newly emerged visual field defect; a missing retinal lesion on fundus examination made the diagnosis challenging but infrared imaging showed a larger area of retinal abnormality temporal to the fovea. Indocyanine green angiography (IA) showed late hypofluorescence and there was mild hyperautofluorescence which is known from acute zonal occult outer retinopathy (AZOOR). Despite normal fluorescein angiography (FA) results, a perfusion loss in the outer retinal layer was detected by OCT-A. Similar OCT-A findings were recently described in patients with acute macular neuroretinopathy (AMN). Methods. The methods included FA and IA, spectral domain optical coherence tomography (SD-OCT), near infrared imaging, and autofluorescence imaging (AF), as well as OCT-A. Patient. A 36-year-old patient who suffered from acute symptoms of photopsia and scotoma on her left eye. She had an influenza-like illness two weeks earlier. The scotoma could be verified by visual field testing. Results. The affected retinal zone showed mild fading of external limiting membrane (ELM) and a disorganisation of the ellipsoid zone (EZ) on SD-OCT. OCT-A revealed a large area of reduced perfusion in the outer retinal vascular layer. Conclusion. OCT-A can help to detect reduced capillary network in patients with visual field defects and no visible fundus changes. This case seems to have features of different occult retinal disorders such as AZOOR and AMN.

  • Bilateral Trichotillomania of Eyelashes Triggered by Anxiety due to
           Nocturnal Enuresis: A Case Report

    • Abstract: Purpose. Trichotillomania is a behavioral and mental disorder and is characterized by a recurring habit of pulling out one’s hair. The differential diagnosis between trichotillomania and other hair loss conditions such as alopecia areata is difficult for ophthalmologists. We report a rare case of bilateral trichotillomania of the eyelashes that was triggered by anxiety about nocturnal enuresis. Case Report. A healthy 9-year-old Japanese boy presented with a bilateral loss of his eyelashes. His parents had believed that his loss of eyelashes was due to alopecia, an autoimmune disorder that results in hair loss, of the eyelashes. Our initial examination revealed that he had suffered from nightly nocturnal enuresis from childhood and was scheduled to go on a school trip the following month. He feared that his school mates might find out about his enuresis, and he said that the anxiety was the cause of the eyelash trichotillomania. The trichotillomania was resolved by discussion among the student, his family, teacher, and school counselor. Conclusion. To the best of our knowledge, this is the first report of eyelash trichotillomania caused by anxiety about nocturnal enuresis. Ophthalmologists should be aware that a patient without eyelashes may not be due to alopecia but some anxiety-producing events. In addition, discussion of the anxiety-producing factor among the parents, teacher, and school counselors can resolve the trichotillomania.

  • Modification of the Intrastromal Ring Position according to Postimplant
           Visual and Refractive Failure: Report of Two Cases

    • Abstract: Objective. The following report presents the adaptation of an existing technique of intrastromal corneal ring (ICRS) implantation enabling repositioning of the ring position postoperatively to manage a refractive failure in two patients with keratoconus. Methods. In two cases, KeraRing and Ferrara nomograms had suggested different ring positions. To manage with the differences between the two nomograms, a longer corneal tunnel was created followed by the classic intervention to move the ring through the initial intrastromal corneal tunnel according to the topographic values. Once the first ring position has failed, the ring segment was repositioned along the longer corneal tunnel according to the postoperative outcome. Results. Significant improvement in both cases was observed in the best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and root mean square (RMS) measured with Scheimpflug imaging (Pentacam; Oculus GmBH, Wetzlar, Germany). The participants were followed for one year. Conclusion. In patients with keratoconus which exhibit significant differences between KeraRing and Ferrara nomograms, a longer tunnel should be created to enable repositioning of the ring postoperatively if necessary, to avoid extracting the ring or changing it.

  • Posterior Microphthalmia, Peripheral Pigmentary Retinal Changes, Yellow
           Lesions, and Cleft Lip: A Case Report and Literature Review

    • Abstract: Purpose. Posterior microphthalmia is a sporadic or inherited developmental ocular anomaly that may occur isolated or in association with multiple ocular and systemic anomalies. This report documents a case of posterior microphthalmia with atypical presentation including white dots in the posterior pole in addition to systemic anomalies including facial defect that can represent an underlying genetic mutation. Method. Case report. Results. A 29-year-old male with high hyperopia and history of bilateral clear lens presented with pigmentary changes and white-yellow dots in the posterior pole in both eyes. Patient had a history of cleft lip repair. A complete ocular evaluation including A/B scan and optical coherence tomography confirmed the diagnosis of posterior microphthalmia with a retinitis pigmentosa like fundus and drusen deposits in the subretinal pigment epithelium. Conclusion. The white-yellow drusenoid deposits in the posterior pole in association with posterior microphthalmia are poorly documented in the literature. Cases of craniofacial developmental defects in association with posterior microphthalmia may represent a genetic defect.

  • Use of Autologous Platelets for Lamellar Macular Hole Repair

    • Abstract: The consensus of lamellar macular hole repair generally entails vitrectomy with internal limiting membrane with/without epiretinal membrane peeling with gas tamponade, although the risk of a full thickness macular hole remains. In this case report, we investigate the role of the regenerative properties of autologous platelets in the repair of a lamellar macular hole with pars plana vitrectomy, an autologous platelet plug, and 12% C3F8 without prone posturing. All three patients in this case report experienced visual improvement along with anatomic closure of the lamellar macular hole. Further randomized studies with larger sample sizes will contribute to the existing data regarding this procedure and its outcomes.
