Purpose. To observe the efficacy and safety of pars plana vitrectomy (PPV) combined with filtered air tamponade in the treatment of rhegmatogenous retinal detachment (RRD) with inferior retinal breaks. Methods. This retrospective study included 20 patients (20 eyes) with inferior retinal breaks in RRD; all underwent PPV combined with filtered air tamponade. Preoperative examinations included BCVA, IOP, anterior segment, fundus and locations, numbers, and sizes of retinal breaks and ocular B-mode ultrasonography. Postoperative examinations included BCVA, IOP, residual gas volume, retinal reattachment, and complications. Results. After follow-up for 1 year, the primary retinal reattachment rate was 95% and the final reattachment rate was 100%. Pre- and postoperative BCVA averaged 1.51 ± 0.63 and 0.97 ± 0.58 logMAR, respectively; the difference was statistically significant ( P < 0.001 ). Average pre- and postoperative IOP were not statistically different. The average volume of residual gas on the first day after the surgery was 77.5%; the gas was absorbed in all patients within 2 weeks; no significant postoperative complications were observed. Conclusion. PPV combined with filtered air tamponade is a safe and effective treatment for RRD with inferior retinal breaks. Notably, the retinal reattachment rate is high, gas absorption is rapid, and incidence of complications is low.

Abstract Background To compare parsplana vitrectomy (PPV) with and without phacoemulsification to treat rhegmatogenous retinal detachment (RRD). Methods Subjects aged 48–65 years with RRD in a phakic eye due to superior retinal tears with an overall extension of retinal breaks < 90° underwent to PPV alone (group A); or PPV plus phacoemulsification (phacovitrectomy, PCV, group B). Post-operative follow-up visits occurred at 1 week, 1 month (m1), 3 months (m3), and 6 months (m6) after surgery. The main outcome was the rate of retinal reattachment. Secondary outcomes included best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT), and cataract progression (in the lens-sparing [PPV-alone] group). Results In this initial phase of the study a total of 59 patients (mean age: 55 years, 59 eyes) were enrolled: 29 eyes in group A and 30 eyes in group B. Both groups had similar gas tamponade. During the follow-up there were three cases of RRD recurrence in group A and one in group B. The relative risk of recurrence in group A was 3.22 times higher but the difference was not significant (p = 0.3). The two groups were also similar in terms of BCVA and IOP variation. At m3, CMT was significantly higher in group B (p = 0.014). In group A, cataract progression was significant at m6 (p = 0.003). Conclusions In a cohort of RRD patients selected according to their preoperative clinical characteristics, PPV was comparable to PCV in terms of the rate of retinal reattachment after 6 months.

Background. Various techniques have been described for repairing cyclodialysis clefts, but there is no consensus regarding the optimal treatment. This study investigated the clinical efficacy of a novel surgical approach that is used to manage traumatic cyclodialysis. Methods. We prospectively enrolled 7 patients (7 eyes) with traumatic cyclodialysis of the concomitant lens and other vitreous diseases. Ultrasound biomicroscopy was used to diagnose cyclodialysis, and all eyes underwent pars plana vitrectomy with air endotamponade. The main outcome measures were postoperative anatomical success rates, best-corrected visual acuity (BCVA), and intraocular pressure (IOP). Results. All patients were male, and their age ranged from 46 to 64 years (mean: 54.3 years). After the surgical intervention, the extent of the cyclodialysis cleft ranged from 1 to 4 clock hours (mean: 2.3 clock hours) and the detached ciliary body of all cases was completely restored; the anatomical success rate was 100%. The BCVA significantly increased from 1.40 ± 0.49 to 0.42 ± 0.31 (P = 0.002). The IOP increased from 8.91 ± 1.77 to 14.67 ± 6.38, but the difference was not significant (P = 0.056). The postoperative IOP of most patients was temporarily elevated or lowered after surgery. At the last follow-up, there were still two abnormal cases, including one with ocular hypertension and one with hypotony. Conclusions. This study revealed that vitrectomy with air endotamponade is an effective and minimally invasive alternative surgical approach for small traumatic cyclodialysis clefts.

Purpose. The object of this study was to investigate the role of the suture stent regarding its impact on reduction of intraocular pressure (IOP) in canaloplasty based on the distension of the inner wall of Schlemm’s canal.Methods. Nineteen glaucoma patients who underwent canaloplasty with successful positioning of the tensioning suture were included. The measurements were analyzed using linear mixed models, with the means adjusted to IOP, age, cup-to-disc ratio, and time of follow-up.Results. Mean follow-up time was 27.6 months (SD 10.5). Mean intraocular pressure (IOP) was 24.6 mmHg (SD 5.29), 13.8 (SD 2.65), and 14.5 (SD 0.71) before surgery, at 12 months, and at 36 months after surgery, respectively. 57.9% of patients had no medication at last evaluation. Differences and variations of measurements between the devices over a time of 12 months were not significant (p= 0.15 to 0.98). Some angles of distension associated with the suture stent inside SC were predictive for IOP reduction (p< 0.03 to < 0.001), but not for final IOP (p= 0.64 to 0.96).Conclusion. The angles of the inner wall of Schlemm’s canal generated by the suture stent were comparable between OCT and UBM and did not change significantly over time. There was a tendency towards a greater distension of Schlemm’s canal, when the difference was larger between pre- and postoperative IOP, suggesting the tensioning suture may contribute to IOP reduction.

AbstractA 57-year-old otherwise healthy male presented to our department seven days following uneventful pars-plana vitrectomy with gas tamponade for a superior bullous retinal detachment in the left eye. Ophthalmic examination revealed anterior segment inflammation with hypopyon and fibrinous exudate. Intra-ocular pressure was 28 mmHg. Posterior segment evaluation was difficult to assess due to the presence of anterior capsule opacification and gas bubble. A Toxic Anterior Segment Syndrome was suspected, and the patient was treated with topical and oral corticosteroid medication in combination with anti-glaucomatous therapy. On follow-up, anterior segment inflammation and ocular hypertension improved. On day ten post-operatively, ocular ultrasonography demonstrated lens material inferiorly with attached retina. The final diagnosis of posterior lens nucleus dislocation with lens-induced uveitis was retained. The patient underwent an uneventful second vitrectomy with aspiration of the dislocated lens nucleus and sulcus three piece-lens implantation. On last follow-up, visual acuity was 20/50 with no relapsing of ocular inflammation and the retina remained reattached.

Abstract Background The effect of air tamponade among patients undergoing vitrectomy with membrane peeling for removal of epiretinal membranes (ERM) is controversially discussed. The aim of the present study was to analyze differences in outcomes between air tamponade and balanced salt solution (BSS) in a study population with preoperative intraretinal cystoid changes. Patients and Methods This randomized study included patients scheduled for pars plana vitrectomy with membrane peeling owing to ERM and intraretinal cystoid changes. Air tamponade or BSS at the end of surgery was applied according to preoperative randomization. Optical coherence tomography and best-corrected distance visual acuity (DCVA) measurements were performed before surgery, 5 days after surgery, and 3 months after surgery. Results From 96 patients included, 85 eyes had full follow-up and could be included for analysis. Median improvement of DCVA was + 16 EDTRS letters (IQR: 8 to 22) among patients with BSS, while it was + 13 EDTRS letters (IQR: 8 to 17) among patients with air tamponade. There was a trend for better improvement of DCVA when BSS was left at the end of surgery, compared to air tamponade, but not reaching statistical significance. Conclusions There were no statistically significant differences concerning resorption of preoperative intraretinal cystoid changes, improvement of visual acuity, and final DVCA between air tamponade and BSS.

PurposeTo review a series of highly myopic eyes with retinal detachment undergoing pars plana vitrectomy with autologous internal limiting membrane (ILM) flap placed over posterior retinal breaks located in areas of choroidal atrophy.MethodsRetrospective review of 13 consecutive patients receiving pars plana vitrectomy with ILM flap over causative breaks, compared with 19 controls receiving the same surgery with ILM peeling but no ILM flap. Main outcome measures included anatomical success rate, visual acuity, number of surgeries and the rate of silicone oil removal.ResultsPatients in the ILM group required 2.08±0.37 interventions versus 2.58±0.75 in the control group (p=0.037). One (1/13; 7.6%) patient in the ILM group required additional unplanned surgery versus 8/19 (42.10%) in the control group (p=0.038). Final anatomical success rate defined as attached retina after silicone oil (SiO) removal was 13/13 in the I-ILM group and 14/19 (73.6%) in the control group (p=0.052). No patients (0/13) in the I-ILM group retained SiO at the end of follow-up versus 4/19 (21.1%) patients in the control group (p=0.061). Best-corrected visual acuity at the end of follow-up was logMAR 0.65±0.36 (20/91 Snellen) in the ILM group and logMAR 0.89±0.44 (20/158 Snellen) in the control group (p=0.20).ConclusionAutologous ILM may help seal posterior retinal breaks and improve the surgical prognosis of retinal detachment due to breaks located over areas of choroidal atrophy within the myopic staphyloma.

Abstract Background To evaluate the effect of internal limiting membrane (ILM) peeling surrounding macular holes (MH) for the function of retina by microperimetry-3(MP-3). Methods This is a prospective, cohort study which included patients with MHs who were treated by 23-gauge 3-port pars plana vitrectomy and ILM peeling with air tamponade. Color fundus photography, retinal optical coherence tomography and MP-3 were performed 1 week before, 1 and 4 months after the operation. In MP-3 examination, a customized follow-up pattern with 45 spots in the central 8° visual field was used. The spots corresponding to the retina surrounding macular holes were selected for comparison of pre- and post-operative function. Results We incuded 44 eyes of 44 patients with best corrected visual acuity (BCVA) of 1.06±0.40 (logMAR). All eyes achieved an anatomical success at 4 months. BCVA significantly improved at 1 month (0.53±0.30, P<0.01) and 4 months (0.31±0.24, P<0.01), respectively. Mean retinal sensitivity (MRS, dB) of the retina surrounding macular hole was 23.46±3.01 dB at baseline, and significantly increased at 1 month (26.25±2.31 dB, u=-4.88, P<0.01) and 4 months(27.14±2.45 dB, t=-6.29, P<0.01). Patients with increased MRS are significantly younger than those with deceased MRS (59.72±3.22 years vs. 65.60±8.19 years, P<0.01). After ILM peeling, the increasing extent of MRS was significantly higher in inferior and nasal retina than in superior and temporal retina at 1 and 4 months (P<0.05). Conclusion ILM peeling in normal retina will not decrease the retinal function in a short-term after surgery.
