Purpose: To estimate long-term results after vitrectomy with internal limiting membrane peeling in vitreomacular traction syndrome (VMTS), as well as to estimate factors influencing final visual outcome. Methods: Medical records of all patients who underwent pars plana vitrectomy for idiopathic VMTS from 2007 through 2015 were assessed. Spectral domain optical coherence tomography was performed preoperatively and at least 6 months after surgery. The mean horizontal and vertical diameters of the vitreomacular traction (VMT) were measured. The area of vitreomacular attachment was calculated. Results: Twenty-four eyes of 22 patients (mean age, 74 years) were included in this study. Mean visual acuity improved significantly from 0.26 Snellen (0.69 logMAR) to 0.39 Snellen (0.43 logMAR) in the mean of 29 months after surgery (7-90 months; median, 25 months; P = .02, paired t test). Visual acuity improved in 18 eyes, remained unchanged in 2 cases, and decreased postoperatively in 4 eyes. Multiple regression analysis did not reveal any factors significant for determining final visual acuity. However, when regrouping the patients according to the International Vitreomacular Traction Study Group, we observed that final visual acuities were statistically significantly better in eyes with focal vitreous detachment compared to broad vitreous detachment ( P = .04). Conclusions: Despite the fact that VMT is a 3-dimensional disease, the calculated area of attachment was not greater than the vertical diameter of attachment. According to the current study, the classification of VMT proposed by the VMT Study Group might be an important tool in predicting the final visual outcome after vitrectomy.

To study the efficacy of pneumatic induction of posterior vitreous detachment for the treatment of vitreomacular traction syndrome, the analysis of the results of surgical treatment of 10 patients (10 eyes) with vitreomacular traction syndrome was performed, among them 8 patients (8 eyes) had an accompanied immature age-related cataract and 2 patients (2 eyes) - pseudophakia. The average age of the patients was 64.1±4.6 years, among them 8 women and 2 men. The mean best corrected visual acuity on admission was 0.31±0.15, the average length of vitreomacular adhesion and retina thickness in the fovea by optical coherence tomography were 289.3±75.4 and 367.5±50.3 μm, respectively. Patients with pseudophakia underwent pneumatic induction of the posterior vitreous detachment, and patients with cataract underwent the same surgery in combination with phacoemulsification of the cataract and intraocular lens implantation. Within 1 month of follow-up, all patients had a complete posterior vitreous detachment and increased best corrected visual acuity. Intraocular pressure remained normal throughout the follow-up period in 9 out of 10 patients, 1 patient experienced hypertension on day 1 after the surgery, which required decompression during the gas expansion period. Further on, intraocular pressure was normalized and did not require therapy. Pneumatic induction of posterior vitreous detachment is an effective method of treatment of vitreomacular traction syndrome, which allows eliminating vitreomacular traction; the combination of pneumatic induction of the posterior vitreous detachment with phacoemulsification of cataract allows avoiding hypertension during and after operation and avoiding performing vitrectomy.

Background: Functional outcome of macular hole (MH) surgery can be better assessed with multifocal electroretinogram (mfERG) and microperimetry (MP). It might provide better assessment than the Snellen visual acuity alone. Objectives: To evaluate macular function with mfERG and microperimetry, and assess their correlation with visual acuity in MH. Materials and Methods: A prospective study was done in patients with unilateral,idiopathic full thickness MH. Standard surgery with vitrectomy, internal limiting membrane peeling and gas tamponade was done. Snellen and logMAR visual acuity, mfERG, microperimetry and optical coherence tomography were done pre and postoperatively. Results: Twenty six patients with unilateral macular hole and twenty five age matched controls were included. The mean age of patients was 59.92±9.39 years (range: 40 to 74 years). All the holes were closed after surgery (two required second surgery). The mean visual acuity improved from 0.77±0.34 logMAR to 0.43±0.36 (p =0.03). The mfERG amplitudes differed ring wise, but the average amplitude changed from 26.31±8.82 to 20.52±7.11 (p =0.03). The mean retinal sensitivity changed from 12.98±2.59 to 13.42±2.53 (p =0.11). There was significant correlation between visual acuity and mfERG amplitudes and retinal sensitivity. Regression equations to predict visual outcome could be derived. Conclusions: In MH, mfERG and microperimetry show reduced responses, delay in recovery of function. They show a strong correlation with visual acuity. It is possible to predict vision after surgery with the help of mfERG and MP. Improved ability to predict visual outcome can increase the utility of anatomic success predictors.

Purpose: To report our anatomical outcome with the internal limiting membrane (ILM) graft procedure in the management of rhegmatogenous retinal detachment (RRD) secondary to optic disc coloboma (ODC). Methods: Description of a new surgical procedure in one eye of one patient who underwent pars plana vitrectomy (PPV) combined with ILM graft technique. Subsequent follow-up included optical coherence tomography (OCT) and visual acuity. Results: After only 1 week, the OCT revealed the ILM graft plugging the retinal tear with complete resorption of subretinal fluid. The sealing effect of this graft persisted after 6 months. However, visual outcome was poor and corrected distance visual acuity was 20/200 as a result of the previous long-standing retinal detachment with loss of photoreceptors. Conclusion: We suggest that ILM graft could be performed as a first line treatment in the management of RRD secondary to ODC. This direct closure of the retinal tears, allows a quick and effective interruption of the communication between the subretinal space and the vitreous cavity. Detecting these retinal tears and applying this technique as soon as possible could achieve not only an earlier anatomical success but obtain good visual results in retinal tears with RRD secondary to ODC. Further studies will be necessary to provide more evidences

Purpose: To evaluate the long term visual, refractive, and corneal tomographic outcomes of epithelium-off accelerated corneal collagen cross-linking (ACXL) in the management of pediatric keratoconus (KC). Methods: This retrospective study included patients under 18 years old with progressive KC who underwent ACXL between 2012 and 2019 at Dicle University Hospital. Complete ophthalmic examination was performed including uncorrected distance visual acuity (UDVA), best spectacle-corrected distance visual acuity (CDVA), manifest refraction, and corneal tomography. Evaluations were performed preoperatively and at 6 months intervals postoperatively. Results: Forty-nine eyes of 49 patients were included in the study. The mean age of patients at the time of ACXL was 14.2 ± 1.8 (range: 9.5–17.3) years. Mean follow up was 4.61 ± 1.90 (range: 2.0–8.1) years. The mean LogMAR UDVA improved from 0.94 ± 0.41 to 0.81 ± 0.43, 0.69 ± 0.41, and 0.67 ± 0.33 after 1, 3, and 5 years respectively ( p = 0.001). The mean LogMAR CDVA improved from 0.58 ± 0.36 to 0.46 ± 0.31, 0.34 ± 0.23, and 0.39 ± 0.27 after 1, 3, and 5 years respectively ( p = 0.015). The mean refractive cylinder improved significantly from 6.01 ± 2.07 diopters (D) to 5.46 ± 1.87, 5.38 ± 2.18, and 5.02 ± 2.31 D after 1, 3, and 5 years respectively ( p = 0.005). As compared to preoperative values, steep keratometry and maximum keratometry were not significantly different ( p = 0.805 and 0.448, respectively) following ACXL, while flat keratometry significantly improved after ACXL ( p = 0.012). Although central corneal thicknesses decreased significantly ( p = 0.029), the decrease in thinnest corneal thickness was not statistically significant ( p = 0.205). Conclusion: Epithelium-off ACXL seems to be effective for halting KC progression with long term clinical benefits in pediatric patients.

Introduction: Seasonal hyper-acute panuveitis (SHAPU) is a sight-threatening disease and its management is challenging. Objective: To study the profile and evaluate the visual outcome of the patients of clinicallydiagnosed cases of SHAPU after treatment. Subjects and methods: A retrospective interventional hospital-based study was carried out involving 21 subjects with clinically-diagnosed SHAPU. The data were retrieved from the record section of the hospital and analyzed. The variables studied were demographic pattern, clinical condition, duration of presentation and visual acuity before and after the treatment. Statistics: The data were analyzed using Epi Info version 2000. Percentage prevalence, mean values with standard deviation, relative risk, 95% CI and p value were calculated. P value of < 0.05 was considered to be significant. Results: Among the 21 cases, the numbers of male and female were 11 (52.4 %) and 10 (46.7 %) respectively. A comparative analysis of gender in children and adults did not show any significant difference (RR=0.47, 95% CI = 0.22 - 1.01, Fisher exact test: p = 0.14). The mean for all ages was 7 ± 12.68 years, while the mean age in pediatric cases was 4.5 ± 3.91 years. Thirteen (61.9%) cases occurred in children below fifteen years. Fifteen (71.4 %) cases reported during September and October. Presenting visual acuity of all cases was less than 3/60. All of them received medical treatment. By the end of the 4th week, seven (33.3 %) patients regained vision to 6/18. Conclusion: SHAPU is more prevalent in pediatric age group. It is equally prevalent among males and females. The visual acuity can improve with early medical treatment. Keywords: SHAPU; panuveitis; steroid; phthisis bulbi DOI: 10.3126/nepjoph.v2i1.3702 Nep J Oph 2010;2(1) 35-38

AbstractTo evaluate the indications and outcomes of perfluoropropane (C3F8) gas injection for symptomatic vitreomacular traction (VMT). A retrospective analysis of eyes with VMT treated with 0.3 mL of C3F8 gas was performed. Patients were not asked to posture after gas injection. In phakic patients, cataract surgery was performed simultaneously. Patients were examined after one week and one month postoperatively. Twenty-nine consecutive eyes of 26 patients with symptomatic VMT who underwent pneumatic vitreolysis were included. A complete posterior vitreous detachment was achieved in 18 eyes (62.1%) after a single gas injection at the final visit. The rate of posterior vitreous detachment was reduced significantly with the presence of epiretinal membrane (ERM) (p = 0.003). Three eyes formed a macular hole (MH) postoperatively and another eye developed a retinal detachment. Mean visual acuity increased significantly after one month (p < 0.008). Pneumatic vitreolysis is a viable option for treating VMT with few adverse events. Patient with concomitant ERM had a significantly lower success rate.

Abstract Background: To report the prevalence of ocular abnormalities and investigate visual acuity in a large Western China cohort of retinitis pigmentosa (RP) patients.Methods: A retrospective study was performed, reviewing the medical records and ophthalmic examination reports of 2,127 eyes from 1,065 RP patients in one eye hospital. The authors investigated the prevalence of ocular abnormalities and the relationship between best corrected visual acuity (BCVA) and macular abnormalities.Results: Nyctalopia (58.2%) and blurred vision (27.1%) were the leading consultation causes. BCVA measurements in the better eyes at first clinical presentation showed that 304 patients (28.5%) were categorised as blind and 220 patients (20.7%) as low vision. The most common ocular abnormalities were cataracts (43.1%) and macular abnormalities (59.7%), including epiretinal membranes (51.1%), cystoid macular oedema (18.4%), vitreomacular traction syndrome (2.4%), macular holes (2.3%) and choroidal neovascular membranes (0.05%). Glaucoma was found in 35 eyes (1.6%). The proportions of epiretinal membranes (P = 0.001) and macular holes (P = 0.008) increased significantly with age. The proportions of vitreomacular traction syndrome (P = 0.003) and epiretinal membranes (P < 0.001) in pseudophakia and aphakia eyes were significantly higher than in eyes that had not received operations (including cataracts and clear lens). Cystoid macular oedema was significantly associated with poorer visual acuity in RP patients with clear lens (P = 0.002).Conclusion: Cataracts and macular abnormalities are common in RP patients. In the macular abnormalities, cystoid macular oedema may have a negative effect on BCVA in RP patients with clear lens.

To identify the preoperative risk factors, type of cataract surgery, cataract grade, and final visual outcome in patients undergoing descemetopexy for DMD. This was a retrospective study in which records of patients who underwent descemetopexy with either air or 20% sulfur hexafluoride (SF6) between 1st July 2014 and 30th June 2017. Grade of cataract, type of surgery, visual outcomes, and site of DMD were recorded.The mean age of the patients was 63.21 ± 5.8 years. Of the total 23 cases undergoing descemetopexy, 20 cases (87%) were after manual small incision cataract surgery (MSICS) and three cases (13%) were post phacoemulsification. The mean duration of presentation with a detachment was 13.03± 10.9 days (1-40 days). The most common types of DMD were total (34.8%) followed by temporal (30.4%) and superior (26.1%). Two patients (8.6%) obtained LOGMAR visual acuity (VA) of 0.0 and 5 of 23 patients (21.7%) achieved LOGMAR VA 0.3 after descemetopexy. Reattachment rates were 87% and three cases had reintervention. : This study identifies mature cataract and pre-existing corneal pathology as major risk factors for DMD during cataract surgery. DMD can be treated effectively and good visual outcome after successful descemetopexy.
