AIM: To evaluate the safety and efficacy of a minimally restricted face-down postoperative positioning following pars plana vitrectomy (PPV) with gas tamponade for primary rhegmatogenous retinal detachment (RRD). METHODS: Patients with primary RRD treated with PPV and gas tamponade and followed up for at least 6mo were selected for the study. All phakic eyes underwent simultaneous cataract surgery. The patients were required to be in a postoperative position that prevented downward flow of retinal tears. Patients with macular detachment were positioned face-down for only a couple of hours. The patients were assessed for preoperative and postoperative best-corrected visual acuity (BCVA), anatomical retinal reattachment rate, and postoperative complications. RESULTS: In total, 40 eyes of 39 patients with primary RRD were included in the study. A single tear was present in 30 eyes (75.0%), multiple retinal tears were present in nine eyes (22.5%), and oral dialysis was present in one eye (2.5%). The anatomical success rate was 90.0% (36 cases) after the primary surgery, and the final anatomical success rate was 100%. The BCVA improved significantly (P<0.001) from 0.75 logarithm angle of resolution (logMAR) preoperatively to 0.12 logMAR at the final visit. Postoperative complications included intraocular pressure elevation (≥25 mm Hg) in 11 patients (27.5%), fibrin formation in two patients (5.0%), pupillary capture of the intraocular lens in two patients (5.0%), and posterior synechia in one patient (2.5%). CONCLUSION: A minimally restricted face-down and flexible postoperative positioning after PPV and gas tamponade for primary RRD is effective and safe.

Purpose: To compare long-term clinical outcomes of pars plana vitrectomy (PPV) combined with intraoperative 360° laserpexy and pars plana vitrectomy combined with scleral encircling for the treatment of primary rhegmatogenous retinal detachment (RRD).Methods: This retrospective, comparative case study included 70 patients who had at least 1 year of follow-up after vitrectomy for primary uncomplicated RRD from 2015 to 2019. The patients were divided into two groups. Group I included 34 patients who underwent PPV + 360° laserpexy (LP), while group II included 36 patients who underwent PPV + scleral encircling (SE). Main outcome measures were the anatomical success rate, the functional success rate, final best-corrected visual acuity (BCVA), and the incidence of post-operative complications. We also examined the long-term changes in axial length, corneal curvature, and refractive error before and after surgery.Results: LP and SE groups showed no significant differences with respect to the primary anatomical success rate (97.05% and 94.44%, respectively; p = 0.592) or the functional success rate (BCVA ≥ 20/40 at final follow-up; 82.35% and 77.78%, respectively; p = 0.635). Detachment reoccurred in three cases (one in the LP group and two in the SE group) because of proliferative vitreoretinopathy; both cases in the SE group had successful anatomical re-attachment after repeating the PPV procedure. Complications included post-operative epiretinal membrane and cystic macular edema, as well as increased intraocular pressure.Conclusions: Primary vitrectomy combined with 360° laserpexy has effectiveness similar to vitrectomy combined with scleral encircling in patients with RRD in long-term clinical outcomes.

Aim. To investigate the anatomical success rates of pars plana vitrectomy (PPV) after primary rhegmatogenous retinal detachment (RRD).Methods. This retrospective study was conducted between December 2008 and October 2014 at Nagasaki University Hospital. The preoperative data recorded included the lens status, location of the retinal tear, whether a tear was visualized, presence of multiple tears, macula status, presence of peripheral lattice retinal degeneration, and best-corrected visual acuity (BCVA). The primary outcome measures were anatomical (primary and final) and functional success (visual acuity better than 6/60).Results. This study evaluated 422 eyes of 411 patients with a mean age of57.7±11.2years. The single-operation reattachment rate (primary anatomical success) was 89.8%. The final anatomical success rate was 100% after 2–6 operations (mean =3.14±1.03). Functional success rate after the primary reattachment operation was 96.7%, while it was 97.2% at the end of the follow-up. Multiple logistic regression analysis of the possible risk factors for the primary anatomical failure showed a significant relation with the 25 G instruments (P=0.002) and the presence of multiple tears (P=0.01).Conclusion. The primary anatomical success of PPV for primary uncomplicated RRD was 89.8% and the final anatomical success rate was 100%.

Purpose:  To study demographic characteristics and treatment outcomes of Rhegmatogenous retinal detachment in a private Vitreo-retinal setup of Lahore. Study Design:  Cross sectional Observational study. Place and Duration of Study:  Private Vitreo-retinal setup, from March 2017 to April 2019. Methods:  Total 102 patients with Rhegmatogenous retinal detachment (RRD) were included. Patients with retinal detachment other than RRD were excluded. Detailed history and ocular examination was performed. Type of break, procedure adopted for RRD repair and type of endo-tamponade were also recorded. These patients had either 23 G pars plana vitrectomy (PPV) or scleral buckling (SB) procedures or combined sclera buckling with PPV. Patients were followed-up for six months. Results:  Out of 102 total RRD cases, 63.70% were males and 36.30%were females. Mean age was 47.44 ± 18.44. Macula was on in 48% and off in 52%. Phakic patients were 46.50%, pseudophakic 48.50% and 5.10% were aphakic. Position of break in RRD was superotemporal in 39.2%, inferotemporal in 30.4% and inferonasal in 2.9%. Total RD was observed in 27.5% patients. One or more breaks were identified in 82.4% patients and giant tear in 4.9%. Three ports 23 G PPV was done in 64.7%, PPV with IOL in 18.6%, scleral buckling in 10.8% and combined PPV + SB in 5.9% patients. The anatomical success rate was observed in 96.07%, 3.9% needed second surgery to get anatomical success in six months follow-up.

Purpose To assess the occurrence of peripheral vitreoschisis-induced vitreous cortex remnants (p-VCRs) in primary rhegmatogenous retinal detachment (RD) and investigate whether the presence of p-VCRs results in a greater risk of RD recurrence, secondary to Proliferative Vitreoretinopathy (PVR) development after pars plana vitrectomy (PPV). Methods Patients who underwent PPV for primary rhegmatogenous RD between January 2016 and December 2018 were included. The presence of residual p-VCRs was confirmed intraoperatively using triamcinolone acetonide (TA). Patients with p-VCRs were divided into two groups: Group A comprised of patients who underwent PPV without p-VCR removal, while Group B included patients who underwent PPV with p-VCR removal. Results Four hundred-thirteen eyes with evidence of p-VCR were analyzed. Two-hundred-twenty-three eyes underwent PPV without VCR removal (Group A), while 190 eyes underwent PPV with p-VCR removal (Group B). Primary anatomical success was 91.5% in the Group A and 95.4% in the group B. Retinal re-detachment due to PVR occurred in 17 (7.6%) eyes in Group A and in four (2.1%) eyes in Group B within the first 3 months (p  =  0.01). Among group A, in 11 eyes, there was a diffuse posterior PVR grade C, while six eyes were focal PVR grade C. In Group B, we observed four retinal re-detachment due to focal PVR grade C. Conclusion The presence of p-VCRs seems to be associated with a higher incidence of PVR development and might also result in more complex RD recurrence, this suggests the need for more aggressive VCRs removal during the first surgery.

Introduction: Rhegmatogenous retinal detachment (RRD) is a potentially blinding condition. Objective: To evaluate the anatomical and functional outcome of surgery of RRD. Materials and methods: A prospective study of interventional case series was designed including 50 consecutive patients with RRD in a tertiary level eye center in Kathmandu. The patients underwent scleral buckling (SB) or pars plana vitrectomy (PPV) according to the proliferative vitreo-retinopathy (PVR) changes. All the patients had at least 3 months of follow-up. The anatomical and physiological outcome measures were primary retinal reattachment and improvement in visual acuity respectively. The surgery was considered successful when there was attachment of retina after the first surgery. Results: The mean age of these patients at the time of presentation was 46.24 ± 19.82 years. Of 50, sixty-six percent of the patients underwent SB and 34 % underwent PPV. Primary surgical success rate was 88 %. While comparing the initial best corrected visual acuity (BCVA) with the final, 72% had an improvement, 12 % unchanged and 16 % had a deteriorated visual acuity. Conclusion: The visual acuity improves and the anatomical success rate is high in the majority of the patients after surgery for rhegmatogenous retinal detachment.

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.

AbstractThe purpose of this study was to evaluate the retinal function by electroretinograms (ERGs) recorded with the RETeval system using skin electrodes after pars plana vitrectomy (PPV) with gas tamponade in eyes with a rhegmatogeneous retinal detachment (RRD). Flicker ERGs were recorded from 17 eyes with an RRD before (baseline), within 2 weeks after the PPV when the size of the tamponade gas was approximately one-half of the vitreous cavity (P1), and when the gas had been completely absorbed (P2). The amplitudes of the flicker ERGs at each phase were compared to that at the baseline. The median (25th, 75th percentile) of the amplitude was 10.0 µV (5.5, 13.0 µV) at the baseline, 11.7 µV at P1 (7.8, 14.8 µV; P = 0.003), and 17.1 µV at P2 (11.7 23.3 μV; P < 0.001). The ratio of the amplitudes in the affected eye to that in the fellow eye at the baseline and at each phase was calculated, and the ratio of the amplitudes at P1 and P2 were significantly and positively correlated (P = 0.723, P = 0.001; Spearman’s rank correlation coefficient). We conclude that recordings the flicker ERGs with skin electrodes can be used to assess the physiology of eyes even with the vitreous cavity half-filled with the gas used to tamponade the retina.

Abstract Purpose: To investigate different fundus vasculature and structure changes after single pars plana vitrectomy (PPV) following silicone oil (SO) or sterilized air in macular-off rhegmatogenous retinal detachment (RRD) patients. Method: 39 eyes (39 patients) with macular-off RRD underwent standard three-port 23-gauge PPV and intraocular SO or gas tamponade. Optical Coherence Tomography (OCT) and angiography were used to evaluate fundus structure and vasculature including retinal layers thicknesses and vessel density (VD) changes throughout observation for 12 weeks. Retinal layers were segmented into: NFL, GCL+IPL, INL, OPL, ONL+IS, OS+RPE and BRM. Fundus vasculature was segmented into superficial and deep capillary plexus (SCP, DCP), and choriocapillaris plexus (CCP). Result: For fundus vasculature, SO tamponade led to significant decrease in both SCPVD and DCPVD, while only SCPVD was found significantly decreased in gas tamponade eyes. For specific retinal layer, SO led to significant decrease in NFL and INL thicknesses. OPL, ONL+IS and OS+RPE thicknesses had significant increase in both SO tamponade and gas tamponade eyes. Conclusion: Different intraocular tamponades could have various impacts on retinal vasculature and structure. Compared to sterilized air, silicone oil tamponade could have relatively more negative effects on retinal vasculature and specific retinal layer thickness change.
