Retrospective study of retinal detachment following neodymium:YAG laser posterior capsulotomy

Background/aimsPreventing and treating proliferative vitreoretinopathy (PVR) remain a serious challenge for vitreoretinal surgeons. PVR is a devastating complication of retinal detachment that results in recurrent detachment and limits visual recovery. At present, there is no effective treatment for PVR.Materials and methodsA retrospective review was performed on a cohort of five consecutive eyes with severe PVR and recurrent retinal detachment that were treated with relaxing retinectomy, extended perfluorocarbon liquid tamponade (4–5 weeks) and a series of intravitreal methotrexate (MTX) injections (100–200 µg/0.05 mL for 10 weeks).ResultsAll five patients remained reattached (100%) with 11–27 months of follow-up (mean = 17.4). 4 eyes recovered ambulatory vision (>20/200) with normal intraocular pressure and non-fibrotic laser scars along with the relaxing retinectomy. The initial patient remained reattached, but only had hand motions vision. The only adverse effect noted was mild superficial punctate keratopathy in one patient.ConclusionThis small, retrospective study suggests that a series of MTX injections may be beneficial for treating complex retinal detachment caused by PVR. Further study is indicated.

Purpose: This retrospective study recorded intraoperative findings during silicone oil removal and postoperative anatomical outcomes comparing endoscopy-assisted pars plana vitrectomy (E-PPV) vs pars plana vitrectomy (PPV) alone after proliferative vitreoretinopathy (PVR)-related retinal detachment (RD) repair. Methods: This single-center retrospective study included patients who underwent PPV for silicone oil removal after RD with PVR from July 2009 to January 2017. Patients with diabetic tractional RD, history of trauma, uveitis, or endophthalmitis were excluded. After 2013, an endoscopic visualization system (E2 MicroProbe; Endo Optiks) was used in a nonrandomized fashion. Data collection included reattachment rate, intraoperative endoscopic findings and phthisis rate. Results: Fifty-four eyes of 54 patients were included. The mean participant age was 58.4 ± 12.9 years and 36 (65.5%) participants were male. The mean (± SD) follow-up duration after oil removal was 24.3 ± 20.1 months. E-PPV combined with wide-angle visualization system was performed in 26 (48.1%) of the patients; the surgical management was modified after endoscopic examination in 17 (65.4%) of the cases. Reattachment rate in the E-PPV group was 96.2% compared with 76.0% in the PPV-alone group ( P = .04). Conclusions: E-PPV for silicone oil removal appears to be advantageous for prevention of RD recurrence, thus achieving better reattachment rates. A thorough examination is facilitated by endoscopic visualization and contributory factors for anterior PVR can be identified and treated.
