Purpose To evaluate the visual outcomes of vitrectomy for lamellar macular hole (LMH) and epiretinal membrane (ERM) foveoschisis and to investigate the prognostic factor for postoperative visual acuity. Methods We retrospectively reviewed 15 LMH and 17 ERM foveoschisis eyes that had undergone a standard three-port pars plana vitrectomy with (12 eyes) or without (20 eyes) cataract surgery. Best-corrected visual acuity (BCVA) at postoperative three months and the final visit were compared to the preoperative measurements. We investigated the relationship between BCVA at the final visit and baseline parameters (age, preoperative BCVA, the presence of epiretinal proliferation [EP] and ellipsoid zone [EZ] disruption). The best explanatory variables for the final BCVA were investigated using the corrected Akaike information criterion (AICc) model selection. Results The mean age was 67.2 years. The mean follow-up duration was 30.7 months. Fifteen of 32 examined eyes were diagnosed as LMH and 17 eyes as ERM foveoschisis. Twelve eyes in LMH had EP and 13 eyes showed the disruption of EZ integrity. In total, BCVA significantly improved at 3 months postoperatively (p = 0.0013). A significant improvement was observed in ERM foveoschisis (p = 0.0085) but not in LMH group (p = 0.071). Comparing the BCVA between the baseline and the final visit, significant improvements were observed in total, ERM foveoschisis and LMH group (p<0.001, p<0.001 and p = 0.026, respectively). The optimal model for BCVA at the final visit included preoperative BCVA and the presence of EZ disruption (p<0.001 and p<0.001, respectively). Conclusion Our results suggested that the final BCVA was dependent on preoperative BCVA and the presence of EZ disruption. Surgical indications might be warranted for LMHs with EZ disruption.

Purpose. We aimed at reminding that X-linked retinoschisis may also be seen in female patients and share our vitreoretinal surgical experience. Methods. The patient underwent pars plana vitrectomy including the closure of the macular holes with inverted ILM flap technique bilaterally. Lens extractions were performed by phacoemulsification during the removal of silicone oil endotamponade. Patient. An 18-year-old girl with X-linked retinoschisis and large macular holes in both eyes presented to the clinic of ophthalmology. It was confirmed that the patient had RS1 mutation Results. Nine-month-follow-up was uneventful for retinal findings. Significant improvement in visual acuity was achieved, and macular holes were remained closed. Conclusion. In cases with large macular holes due to XLR, an inverted ILM flap technique might be safe and effective. Four-month-silicone-endotamponade might be sufficient.

Purpose: To evaluate long-term visual prognosis and changes in the retinal microstructure in patients with macular telangiectasia type 2.Methods: Retrospective analysis of medical records were performed for 61 eyes (32 patients) diagnosed with macular telangiectasia type 2. The visual acuity at diagnosis was compared with that at the final visit. In addition, cases were classified into three grades based on optical coherence tomography (OCT) findings: grade 1, inner retinal cavities only; grade 2, outer retinal cavities with ellipsoid zone disruption; and grade 3, ellipsoid zone disruption with proliferation of retinal pigment epithelium. Change in the grade during the follow-up was verified. In addition, visual acuities were compared between eyes with and without a change in grade.Results: The mean follow-up period was 41.5 ± 33.2 months. Visual acuity had deteriorated significantly from the mean logarithm of the minimal angle of resolution 0.23 ± 0.26 at diagnosis to a mean of 0.31 ± 0.31 at the final visit (p < 0.001). When classified using OCT, 65.6%, 22.9%, and 11.5% were grades 1, 2, and 3, respectively, at diagnosis and 47.5%, 36.1%, and 16.4% at the final visit. Progression of grade was noted in 22.9%. A higher degree of visual deterioration was noted in eyes showing progression than in eyes without (p = 0.002).Conclusions: During the long-term follow-up period, visual deterioration was noted in patients with macular telangiectasia type 2. However, the degree of deterioration was not high. Progression in the disruption of the retinal microstructure was the likely cause of visual deterioration.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and needs further surgery. The purpose of this study is to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD.Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included the causative factors, visual outcomes of RD recurrence, and the perioperative factors most affecting the recurrence of RD.Results After retinal reattachment, we observed recurrence of RD after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most recurrence (69%) occurred within 6 months after surgery. Univariate analysis showed that the primary risk factor significantly associated with recurrent RD was the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C ( P = 0.003). Logistic regression analysis showed that a PVR ≥ Grade C (odds ration [OR]: 9.421, 95% confidence interval [CI]: 2.432 - 56.39; P =0.020) was a significant predictor for the development of recurrent RD. The recurrence of RD resulted in a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit compared with the reattachment group ( P =0.000). Eyes with PVR prior to primary surgery or at the diagnosis of re-detachment showed a worse final BCVA.Conclusions The presence of PVR ≥ Grade C was the predominant risk factor for the recurrence of RD. PVR prior to primary surgery, or at the diagnosis of re-detachment, limited the recovery of final visual acuity.

Purpose. To compare the results of vitrectomy with those of internal limiting membrane (ILM) peeling or inverted ILM flap for treating myopic or idiopathic macular hole. Methods. Thirty-nine eyes of 39 patients undergoing vitrectomy with ILM peeling for macular hole (25 idiopathic and 14 myopic) and 27 eyes of 27 patients undergoing vitrectomy with inverted ILM flap (15 idiopathic and 12 myopic) were included. Outcome measures were macular hole closure by optical coherence tomography and visual acuity at 6 months. Results. Closure was achieved in 25 (100%) idiopathic and 12 (86%) myopic macular holes in the ILM peeling group and in 14 (93%) idiopathic and 11 (91.77%) macular holes in the inverted ILM flap group. There were no statistically significant differences in restoration of the external limiting membrane and ellipsoid zone between the groups. Median best-corrected visual acuity (logarithm of minimal angle of resolution) at the end of follow-up was 0.22 (20/32 Snellen) in idiopathic and 0.4 (20/50) in myopic (P=0.042) patients in the ILM peeling group and 0.4 (20/50) in idiopathic and 0.4 (20/50) in myopic (P=0.652) patients in the inverted ILM flap group. Conclusion. Both techniques were associated with high closure rates in myopic and idiopathic macular holes, with somewhat better visual outcomes in idiopathic cases. The small sample size may have provided insufficient power to support the superiority of one technique over the other in the two groups.

AIM: To evaluate the clinical effectiveness of intrastromal corneal ring segments (ICRS) among the patients suffering from keratoconus. METHODS: A retrospective and non-comparative interventional design had been utilized on the basis of postoperative follow-up among 56 keratoconus patients. Visual acuity was significantly assessed during complete ophthalmic examination of the patients. The femtosecond laser had been used to create the corneal tunnels in 15 eyes; whereas, the corneal tunnels were created in 72 eyes mechanically. RESULTS: The ranges and standard deviations had been used to obtain results. It had been revealed through ophthalmic assessment that the mean preoperative uncorrected visual acuity observed was 1.38±0.37 logarithm of Minimal Angle of Resolution. Moreover, a significant improvement was observed postoperatively in visual acuity by 0.58±0.32 during the 4th month. The improvement was also witnessed in the 16th month by 0.48±0.30. CONCLUSION: The implantation of ICRS is an efficient and effective surgical intervention for the treatment of keratoconus. Thus, identified intervention seems to be associated with appropriate visual outcomes and safety after the development of femtosecond as well as mechanical tunnels.

Purpose: This work compares best-corrected visual acuity (BCVA) and central retinal thickness (CRT) outcome measures following pars plana vitrectomy (PPV) with and without internal limiting membrane (ILM) peel for epiretinal membrane (ERM). Methods: A retrospective cohort study was conducted of 114 eyes of 114 patients with visually significant ERM undergoing PPV with membrane peel (PPV/MP) at a single institution. CRT measurements were collected from Heidelberg and Zeiss spectral-domain optical coherence tomography imaging units. Results compared preoperative and postoperative CRT and BCVA among patients with at least 60 days of follow-up. Results: A total of 114 eyes with ERM met the inclusion criteria. Eighty-one eyes (71%) underwent PPV/MP with ILM peel and 33 eyes (29%) underwent PPV/MP without ILM peel. There was no statistically significant difference between preoperative CRT between the 2 study groups ( P = .95). The mean follow-up time of eyes undergoing PPV/MP without ILM peel and with ILM peel was 391 days and 319 days, respectively. There was no statistical difference in the mean reduction of CRT between the 2 groups ( P = .470). Both groups had improvement of BCVA following surgery and there was no statistical difference in final logMAR visual acuity when comparing the 2 groups ( P = .738). Conclusions: There was an overall improvement of CRT and BCVA among patients undergoing PPV/MP for ERM with or without ILM peel. There was no statistically significant difference in the final BCVA or CRT between the 2 groups.

Purpose: The authors aim to describe the visual outcomes and postoperative complications of concurrent pars plana vitrectomy and scleral-fixated intraocular lens (IOL) placement using Gore-Tex suture. Methods: A retrospective review of medical records was performed on 27 eyes of 27 patients undergoing concurrent pars plana vitrectomy and scleral-fixated IOL with Gore-Tex suture. Outcome measures were change in preoperative and postoperative visual acuity, final manifest refraction, and incidence of intraoperative and postoperative complications. Results: The mean age was 69.2 ± 11.3 years; there were 16 male patients (59%). The duration of follow-up ranged from 33 to 576 days with a mean of 200 ± 143 days. All patients received Bausch + Lomb Akreos AO60 IOL. The overall mean best-corrected visual acuity in Snellen equivalent improved from 20/276 preoperatively to 20/44 postoperatively ( P < .001). The mean postoperative manifest spherical equivalent refraction was –0.35 ± 1.34 diopters (D). Seventy-five percent of eyes were ± 1.0 D of target refraction. Postoperative complications included corneal edema (26.0%), ocular hypertension (25.9%), hypotony (7.4%), cystoid macular edema (7.4%), vitreous hemorrhage (7.4%), and hyphema (3.7%). No cases of suture breakage, IOL dislocation, retinal detachment, or uveitis–glaucoma–hyphema syndrome were identified. Conclusions: The use of Gore-Tex suture for posterior chamber IOL fixation resulted in favorable outcomes. No suture-related complications occurred during the follow-up period. Final refraction in this setting is typically within ± 1.0 D of target.

Introduction: Large macular holes are not uncommon among Nepalese women population causing severe visual problem. Objective: To evaluate the technique of inverted internal limiting membrane (ILM) flaps for the repairment of large macular holes. Methods: All 10 macular holes (diameter > 400 μm) were treated with pars planavitrectomy with inverted ILM flap technique. The procedure for macular hole surgerywas pars plana vitrectomy, posterior vitreous removal, internal limiting membrane(ILM) peeling with brilliant blue assisted, inverting ILM flap into macular hole, filling of the vitreous cavity with a gas bubble(C3 F8) and post-operative face-down positioning for 1 week. SD OCT images were taken preoperative and postoperative 1 month and 3 months follow up to assess the anatomical outcome of surgery and best corrected visual acuity (BCVA) was used to evaluate the functional outcome during each visit. The BCVA was recorded using the Snellen chart and was converted to the logarithm of the minimum angle of resolution (LogMAR) equivalents. Results: All 10 eyes had complete anatomical closure. The mean age of patients was 64.3 ± 7.53 years. The mean macular hole base diameter was 1039.4 μm (663-1526μm). Mean BVCA pre-operatively was 1.29 log MAR ±SD 0.25. Post-operatively, mean BCVA was 0.925 log MAR ±SD 0.143 (p= 0.002). There were no intra operative or post-operative complications. All the patients were followed up for a period of 3months. Conclusions: Inverted ILM flaps is effective for closure of the large macular hole and restoration of functional vision.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and requires further surgery. The purpose of this study was to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD. Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included causative factors, visual outcomes related to the recurrence of RD, and the perioperative factors most affecting the recurrence of RD. Results After retinal reattachment, we observed RD recurrence after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most causes of recurrence (69%) occurred within 6 months of surgery. Univariate analysis showed that the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C was significantly associated with recurrent RD (P = 0.003). Logistic regression analysis further showed that a PVR ≥ Grade C (odds ratio [OR]: 9.421; 95% confidence interval [CI]: 2.432 - 56.39; P = 0.020) was a significant predictor for the development of recurrent RD. Compared with the reattachment group, the recurrence group exhibited a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit (P = 0.000). Eyes with PVR prior to primary surgery, or at the diagnosis of re-detachment, showed a worse final BCVA. Conclusions Our analysis shows that the predominant risk factor for the recurrence of RD is a PVR ≥ Grade C. PVR prior to primary surgery, or at the diagnosis of re-detachment, was also shown to limit the recovery of final visual acuity.

AIM: To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis. METHODS: Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy (PPV) combined with scleral shortening were reviewed. Axial length (AL), the height of macular retinoschisis, the height of retinal detachment if existed, the diameter of macular hole if existed and best corrected visual acuity (BCVA) were obtained. The preoperative and postoperative parameters were compared. RESULTS: At postoperative 24mo, the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51 μm (t=8.064, P<0.0001; Z=-5.086, P<0.0001) respectively. In addition, the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38 μm and 183.68 μm (Z=-4.457, P=0.000008; Z=-2.983, P=0.003) respectively. Meanwhile, the postoperative BCVA was improved markedly (Z=-2.126, P=0.033). CONCLUSION: Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis, whether or not macular hole and retinal detachment are present.
