  • Outcomes of retained intraocular foreign body removal by pars plana

    • Abstract: Propose:Intra-ocular foreign body (IOFB) injuries refer to a foreign body present inside the interior of the globe. There is increasing IOFB morbidity in modern life. Intra-ocular foreign bodies may be removed by pars plana vitrectomy.Patients and Methods:The present study was a case series prospective interventional study conducted on 34 patients who underwent pars plana vitrectomy for IOFB removal during the period from November, 2019 to October, 2020, and attending to the outpatient and emergency unit of Mansoura Ophthalmic Center, Mansoura University. The patients were examined then scheduled for through anterior segment approach.Results:The mean age of the studied patients was 34.94±10.946years. The patients(94.1%) were males. Most of the studied patients were at occupational exposure(73.5%), The results showed that most of IOFBs in the studied patients were metallic(64.7%), while 35.3% were non-metallic. The mean value of initial BCVA was 0.05±0.081 that improved at 1 week after operation to the mean value of 0.13±0.121,and then continue to improve in the follow-up visits to 0.16±0.156 in the 2nd visit after 3weeks, 0.19±0.176in the 3rd visit after 8 weeks and 0.24±0.223 in the 4th visit after 12weeks. There were 2cases of raised IOP(5.9%),1case ended with macular scar(2.9%),corneal edema was persistent in one case(2.9%),and PVR was noted in 5 cases(14.7%).Conclusion:IOFB removal by PPV through anterior segment technique was effective, safe, with minimal complications, and Better visual outcome. Improvement of the final BCVA can be predicted by foreign body size, impaction site, initial visual acuity, afferent pupillary defect, Ocular trauma score.
  • Analysis of Optic Nerve Head Parameters in Different Refractive States
           Pediatrics Using Spectral Domain Optical Coherence Tomography

    • Abstract: Purpose: Normative values of optic disc cup size in pediatric age group using spectral domain OCT with correlations to refractive error and axial length.Methods: An observational cross-sectional study recruiting 174healthy children from Nile delta region aged6 to 16years with no ocular comorbidity except refractive error. A thorough examination of the eyes was conducted, and the Cirrus OCT device was used to quantify axial length, RNFL,and macular thickness. Main outcome parameters were macular volume, macular thickness and RNFL thickness values as well as their correlations with age, refractive error and axial length. Right eyes of all subjects were selected for analysis.Results: One hundred and seventy-four children were included in the study,74females and 100males. They were divided into3groups according to their refractive error.Group1(80)emmetrope, group2(62)Myopes and group3(32)hypermetropes.Average spherical equivalent refraction (SE) was-0.20 ±0.77diopters in group1,-3.17±1.27in group2and1.77±0.57diopters in group 3.And average axial length was22.97±.738mm in group1, 23.86±0.925in group2and22.97±0.67mm in group3.According to those results, there were statistically significant differences among the studied groups as regards the mean values of disc area, and H disc diameter(p<0.05),but no statistically significant differences were found among the studied groups as regards the mean rim area(p>0.05).Regarding disc area, statistically significant differences were found when comparing group(1)with group(2),and group(2)with group(3).Conclusions:The axial length is an important factor in defining disc size, which is a crucial component in determining cup to disc ratio, when it comes to spectral domain OCT optic disc properties. Normal children with significant cupping should be evaluated for axial length, myopic refractive defects, and disc size.
  • Comparison between three snip punctoplasty and silicone tube stent in
           patients with primary punctal stenosis

    • Abstract: Purpose: The aim of this study is to compare safety and efficacy of three snip punctoplasty versus bicanalicular silicone intubation in patients with primary punctal stenosis. Patients and methods: This study included 40 eyes with primary punctal stenosis (lower punctum) who were classified into two groups according to the surgical correction technique; three snip punctoplasty (group 1) and bicanalicular silicone Intubation (group 2). All included cases were subjected to ophthalmic history taking and full ophthalmological examination including evaluation of the lacrimal tear strip, fluorescein dye disappearance test, syringing and degree of epiphora. Patients were assessed at one day, one week, one month, three month and six months postoperative for evaluation of silicone tube stability, patency of the punctum, lacrimal tear strip, fluorescein dye disappearance test and degree of epiphora.Results: There was highly statistically significant improvement in the fluorescein dye disappearance test and grading of epiphora in the two groups starting from the first day postoperative. The incidence of patient satisfaction was higher in the silicone Intubation group, but it didn’t reach a statistically significant value. Recurrence of epiphora was reported in two cases in group 1 and in 1 case only in group 2.Conclusion: This study showed that bicanalicular silicone intubation was superior to three-snip punctoplasty for management of primary punctal stenosis.
  • Myopia progression in Egyptian Urban children under the influence of
           online learning during the COVID-19 pandemic

    • Abstract: Purpose: To evaluate myopic progression in school aged Egyptian urban children secondary to online learning during the COVID19 pandemic. Patients and Methods: A cohort study of 105 children aged 8–16 years with myopia of -0.75D or greater. Inclusion criteria were the presence of hospital records for at least two years before presentation and one year after, minimum 6 months of online learning. Patient demographics, type of device, duration of device use, and changes in myopia (over time) were recorded. Results: The mean age was 12±2 with 51.4% males and 48.6% females. The average daily screen time was 5 ±1 hours. Tablets were the predominant device used (48.6%), 43.8% of children had a break time of 60 minutes, and 37.1% of children had > 2h of daily outdoor activities. The rate of annual myopia progression was significantly higher during the target period of online learning (MP(T) = -0.61 D±0.24) compared to myopia progression in the year before (MP(B) = -0.54 D ±0.2) and the year after (MP(A) = -0.53 D±0.21) (p value 0.005& 0.019 respectively). MP(T) significantly increased in children who stayed greater than or equal five hours in front of screen compared to the year before and after online learning (P=0.009, 0.017 respectively), with less than two-hour outdoor activity (P value 0.003 & 0.005 respectively) without taking a break (P=0.004). Conclusion: Online learning and lack of outdoor activities during the COVID19 pandemic significantly accelerated myopia progression rate in Egyptian urban children.
  • Assessment of Macular and Choroidal Changes After Intravitreal Anti-VEGF
           Injections in Diabetic Patients with Diabetic Macular Edema

    • Abstract: purpose : to assess the macular and choroidal alterations using optical coherence tomography imaging at baseline and one month after receiving intravitreal antivascular growth factor (anti-VEGF) (ranibizumab) therapy in patients who had diabetic macular edema .Methods: This was a prospective clinical study which was conducted on twenty eyes with type 2 diabetes with clinically significant macular edema . The intravitreal injection (IVI) of ranibizumab 0.3 mg was administered to the patients (0.05 mL). Prior to the injection and one month later, the central macular thickness, subfoveal choroidal thickness , choroidal thickness 500 m temporal and nasal to fovea were all assessed by SD-OCT. Results: Postoperatively, the mean nasal, subfoveal and temporal choroidal thickness were 175.7±34.55, 185.6±29.13 and 183.9±34.62µm respectively. There was a statistically significant change in the best corrected visual acuity BCVA (p =0.04), the mean preoperative BCVA was 0.875±0.202 while the mean postoperative BCVA was 0.76 ± 0.22. The postoperative BCVA had a statistically significant (p= 0.03) negative correlation with the retinal thickness (r= -0.242), while it didn’t have a significant correlation with the nasal, subfoveal and temporal choroidal thickness (p= 0.275, 0.248 and 0.343) respectively. Conclusion: Injection of LUCENTIS® resulted in a decrease in choroidal thickness, which is a reflection of the impact LUCENTIS® had on the choroidal vasculature. There was a substantial difference between the BCVA before injection and the BCVA one month after it, and this difference had a clear link to the thickness of the retina but not the thickness of the choroids.
  • Chandelier-assisted segmental scleral buckling for rhegmatogenous retinal
           detachment repair

    • Abstract: Aim: To evaluate a modified technique for SB surgery using chandelier endoillumination and minimal segmental buckling through a small conjunctival incision in rhegmatogenous retinal detachment repair.Methods: A prospective interventional case study included 30 phakic eyes with primary RRD that was repaired by chandelier assisted SB using wide angle viewing (WAV) contact lens. Transconjunctival traction sutures were placed in four rectus muscles to avoid 360° conjunctival peritomy. A radial conjunctival opening was made between recti muscles over the break. Using pediatric speculum to retract the conjunctiva and Tenon’s capsule pre-placed 5-0 Dacron mattress suture was secured in the area planned for buckle placing after break marking and cryotherapy. A radial sponge of appropriate length and width was tightened with sutures in place. Anatomical and visual outcome at 6 months were the major outcome measures. Minor outcome measures included other postoperative complications.Results: The mean ± standard deviation BCVA was improved from 0.33±0.61 preoperatively to 0.13±0.36 logMAR units 6 months postoperatively. External subretinal fluid drainage was performed in 18 cases (60%). Air injection was required in 26 patients (87%). Paracentesis was performed in 11 cases (37%).The primary anatomical success of retinal reattachment was achieved in all cases. Three patients (10%) experienced epi-retinal membrane (ERM) formation after 3 months. No other surgical complications were detected during follow up period. Conclusion: In conclusion, SB using a cannula-based chandelier endo-illuminator is a modified new technique and is promising for the management of RRDs.
