Cataract Surgery Outcomes in Eyes With Primary Epiretinal Membrane.

ABSTRACT: Importance:Primary epiretinal membrane (ERM) is a common retinal disorder with a prevalence of 4% to 18.5%. Although ERM and cataracts commonly occur together, to our knowledge, no studies have investigated the outcome of cataract surgery alone in this setting. Objective:To analyze the visual outcome and cystoid macular edema risk with cataract surgery in eyes with primary ERM. Design, Setting, and Participants:In this retrospective clinical database study, data were collected from July 2003 to March 2015 from 8 locations in the United Kingdom. Cataract surgery data of 217?557 eyes were extracted from the electronic medical record of the UK National Health Service. After exclusion of 57?561 eyes with combined surgery, prior vitrectomy, copathology, and complications, 812 eyes with primary ERM and 159?184 reference eyes were analyzed. Main Outcomes and Measures:We report on visual acuity (VA), the incidence of cystoid macular edema, and the need for ERM surgery. Results:The mean (SD) age of patients in the ERM group was 73.7 (9.23) years, and 395 of 812 were men (46.8%). The mean (SD) age of patients in the reference group was 74.4 (12.19) years, and 65?265 of 159?184 were men (41%). Epiretinal membrane eyes assessed at 4 to 12 weeks postoperatively gained 0.27 (0.32) logMAR (approximately?3 Snellen lines), with 200 of 448 (44.6%) improving by 0.30 logMAR or more (?3 Snellen lines) and 32 of 448 (7.1%) worsening by 0.30 logMAR or more. Reference eyes gained a mean (SD) of 0.44 (0.26) logMAR (approximately?4 Snellen lines), with 48?583 of 77?408 (62.8%) improving by 0.30 logMAR or more and 2125 of 77?408 (2.7%) worsening by 0.30 logMAR or more. Although all eyes with preoperative VA of 20/40 or less improved, only reference eyes with preoperative VA of more than 20/40 showed improvement. Cystoid macular edema developed in 57 of 663 ERM eyes (8.6%) (95% CI, 6.69-10.98) and 1731 of 125?435 reference eyes (1.38%) (95% CI, 1.32-1.45) (P?

Project description:Purpose:To assess the retinal architecture changes which occur during epiretinal membrane (ERM) surgery, utilizing intraoperative optical coherence tomography (iOCT). Design:Prospective multi-surgeon single center study. Subjects/Participants:Subjects from the PIONEER iOCT study who underwent surgical intervention for management of ERM. Methods:All subjects underwent vitrectomy with ERM peeling with optional internal limiting membrane (ILM) peeling. Preoperative, intraoperative, and postoperative quantitative and qualitative OCT assessments were performed. Clinical characteristics including visual acuity outcomes, central subfield thickness and complications including ERM recurrence and need for reoperation were assessed at 3, 6 and 12 months following surgery for membrane peeling, as available. Main Outcome measures:Visual acuity outcomes, anatomic outcomes and complications including ERM recurrence. Microarchitectural alterations (i.e. retinal layer changes) following membrane peeling visualized with iOCT. Results:Seventy-six were identified and included in this analysis of clinical outcomes and quantitative OCT assessment. Twenty-four eyes were excluded due to insufficient intraoperative OCT quality for quantitative assessment. The mean preoperative VA measured 20/63. The mean postoperative VA at 3 months was 20/41 (p<0.0001), at 6 months measured 20/36 (p < 0.0001), and at 12 months measured 20/33 (p < 0.0001). Preoperative mean central subfield thickness (CST) was 426 microns. At 3 months, the mean CST improved to 377 microns (p < 0.0001). The 6-month postoperative CST was 367 microns (p < 0.0001) and the 12-month postoperative CST measured 359 microns (p < 0.0001). Immediately following membrane peeling, the distance between the retinal pigment epithelium and the ellipsoid zone as well as the distance between the retinal pigment epithelium and the cone outer segment tips/interdigitation zone significantly increased (p < 0.001). iOCT identified occult residual membranes in 12% of cases and confirmed complete membrane peeling contrary to surgeon impression in 9% of cases. Reoperation was required for recurrent ERM in 1% of eyes. Conclusions:iOCT-assisted ERM peeling resulted in significant improvement in visual acuity, reduction in macular thickness, and low recurrence rate. Additional research is needed with randomized clinical trials to better define the comparative success rates of image-guided ERM surgery to standard surgical visualization techniques.
