360-degree intra-operative laser Retinopexy for the prevention of retinal re-detachment in patients treated with primary pars plana vitrectomy
Graefe's Archive for Clinical and Experimental Ophthalmology, 2020Co-Authors: Ali Dirani, Fares Antaki, Marc-andré Rhéaume, Danny Gauthier, Louis Corriveau, Jean-daniel Arbour, Karim HammamjiAbstract:Purpose To investigate the effect of 360° intra-operative laser Retinopexy (ILR) for the prevention of retinal re-detachment in patients treated with pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). Methods A retrospective single-institution cohort study was performed. Consecutive patients with primary uncomplicated RRD who underwent 23-gauge PPV with gas endotamponade between July 2013 and July 2016 were included in the study ( n = 151). Two cohorts were compared: one which received laser Retinopexy only around identified tears/holes/lattice zones (Control group, n = 86), and one which received additional 360° intra-operative laser Retinopexy (360° ILR group, n = 65). Results Retinal re-detachment was seen in 4/65 eyes (6%) in the 360° ILR group compared to 18/86 eyes (21%) in the control group. In multiple logistic regression, the 360° ILR was associated with a 75% reduction in the odds of retinal re-detachment compared to control (OR = 0.248, 95% CI [0.079–0.772], p = 0.016). There was no statistically significant difference in the incidence of epiretinal membrane formation between the two groups. Conclusions Intra-operative 360° laser Retinopexy during PPV with gas endotamponade resulted in a significant reduction in the odds of postoperative retinal re-detachment in eyes with uncomplicated primary RRD.

real time in vivo assessment of retinal reattachment in humans using swept source optical coherence tomography
Investigative Ophthalmology & Visual Science, 2021Co-Authors: Aditya Bansal, Tina Felfeli, Wei Wei Lee, Rajeev H MuniAbstract:Purpose To assess the in vivo physiology of retinal reattachment in humans using swept-source optical coherence tomography (SS-OCT) in real time. Design Prospective case series. Methods Fifteen consecutive patients with fovea-involving rhegmatogenous retinal detachment were undergoing pneumatic Retinopexy. SS-OCT was performed at presentation and frequent intervals immediately after pneumatic Retinopexy. The primary outcome was longitudinal assessment of early postoperative SS-OCT to establish stages of reattachment. Results Most patients (93.3%, 14/15) achieved successful reattachment at the median follow-up duration of 13 weeks (interquartile range 7.5-18.0). Reattachment occurred in 5 specific stages: 1) redistribution of fluid and approach of the neurosensory retina toward the retinal pigment epithelium occurred in 100% (15/15); 2) reduction in cystoid macular edema and improvement of outer retinal corrugations was achieved in 100% (15/15); 3) initial contact of the neurosensory retina to the retinal pigment epithelium occurred completely in 66.7% (10/15); 4) deturgescence of the inner and outer segments of the photoreceptors occurred in 66.7% (10/15); and 5) recovery of photoreceptor integrity occurred in 3 specific substages: 5A) external limiting membrane recovery (10/15, 66.6%); 5B) ellipsoid zone recovery (9/15, 60%); and 5C) interdigitation zone/foveal bulge recovery (3/15, 20%). Twenty percent (3/15) had delayed progression through stage 2, characterized by formation of outer retinal folds. Similarly, 33.3% (5/15) developed residual subfoveal fluid blebs (delayed progression to stage 3). Conclusions This study characterizes the in vivo physiology of retinal reattachment in humans using high-resolution SS-OCT that occurs in 5 specific stages. Delayed progression through certain stages was characterized by postoperative anatomic abnormalities. Am J Ophthalmol 2021;221:•••–•••. © 2021 Elsevier Inc. All rights reserved.

the pneumatic Retinopexy versus vitrectomy for the management of primary rhegmatogenous retinal detachment outcomes randomized trial pivot
Ophthalmology, 2019Co-Authors: Roxane J Hillier, Tina Felfeli, Alan R Berger, David T Wong, Filiberto Altomare, David Dai, Louis R Giavedoni, Peter J Kertes, Radha P Kohly, Rajeev H MuniAbstract:Purpose The optimal surgery to repair rhegmatogenous retinal detachment (RRD) is unknown. The purpose of this trial was to compare outcomes of pneumatic Retinopexy (PnR) versus pars plana vitrectomy (PPV) for the management of primary RRD. Design Prospective, randomized controlled trial. Participants Patients with RRD demonstrating a single retinal break or a group of breaks in detached retina within 1 clock hour above the 8- and 4-o’clock meridians, with any number, location and size of retinal breaks or lattice degeneration in attached retina. Methods Patients were randomized to undergo either PnR or PPV. Macula-on and macula-off patients were assigned to intervention group by stratified randomization and were treated within 24 and 72 hours, respectively. Main Outcome Measures The primary outcome was 1-year Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA). Important secondary outcomes were subjective visual function (25-item National Eye Institute Visual Function Questionnaire), metamorphopsia score (M-CHARTS), and primary anatomic success. Results One hundred seventy-six patients were recruited between August 2012 and May 2016. ETDRS VA after PnR exceeded that after PPV by 4.9 letters at 12 months (79.9±10.4 letters vs. 75.0±15.2 letters; P = 0.024). Mean ETDRS VA also was superior for the PnR group compared with the PPV group at 3 months (78.4±12.3 letters vs. 68.5±17.8 letters) and 6 months (79.2±11.1 letters vs. 68.6±17.2 letters). Composite 25-item National Eye Institute Visual Function Questionnaire scores were superior for PnR at 3 and 6 months. Vertical metamorphopsia scores were superior for the PnR group compared with the PPV group at 12 months (0.14±0.29 vs. 0.28±0.42; P = 0.026). Primary anatomic success at 12 months was achieved by 80.8% of patients undergoing PnR versus 93.2% undergoing PPV (P = 0.045), with 98.7% and 98.6%, respectively, achieving secondary anatomic success. Sixty-five percent of phakic patients in the PPV arm underwent cataract surgery in the study eye before 12 months versus 16% in the PnR group (P Conclusions Pneumatic Retinopexy should be considered the first line treatment for RRD in patients fulfilling Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) recruitment criteria. Pneumatic Retinopexy offers superior VA, less vertical metamorphopsia, and reduced morbidity when compared with PPV.
