Abstract Details

Purpose:

To describe functional and anatomical outcomes of epiretinal membrane (ERM) in patients previously treated for retinal detachment (RD).

Setting:

Institut Català de Retina, Barcelona, Spain

Methods:

Retrospective review of a consecutive case-series of patients who developed ERM after previous RD in 2012 -2016. Demographic, preoperative and postoperative data were analyzed. Best-corrected visual acuity (BCVA) and OCT characteristics were registered at baseline when the ERM was diagnosed and during follow-up at 3, 6, 12 months and at the final visit.

Results:

67 patients (70 eyes) were included. BCVA before and after RD repair was 0.5±0.4 and 0.6±0.3, respectively. The majority of patients had uncomplicated RD (75.5%), macula-involving RD (51%) and were pseudophakic (44.9%). Surgical approaches to RD repair were vitrectomy (VPP) (n=13), scleral buckle (n=10) or combination of both (n=26). Mean interval between RD and ERM diagnosis was 169±282 days. Mean BCVA at baseline and during follow-up at 3, 6, 12 months, and final visit was 0.5±0.3, 0.6±0.3, 0.6±0.3, 0.7±0.3 and 0.8±0.3, respectively. Mean central foveal thickness (CFT) at baseline and during follow-up at 3, 6, 12 months, and at the final visit was 381±119, 429±166, 380±90, 360±79 and 345±49 µm, respectively. Applied treatments included vitrectomy with ERM peeling (44.9%), subtenon´s triamcinolone injection (8%) and cataract surgery alone (28.6%). Although there were no differences in mean central foveal thickness (CFT) between the ERM peeling and the observation group (354±46 vs 338±51), BCVA differed between groups (0.6±0.3 vs 0.9±0.2). This was also observed when comparing complicated and no complicated RD, macula-involving and macula-sparing RD, ellipsoid line disruption or integrity and in different surgical approaches.

Conclusions:

Epiretinal membrane after RD repair did not result in BCVA deterioration at the final follow-up visit when compared to BCVA in patients without ERM. In subgroup analysis differences in BCVA were observed, even though there were no differences in anatomical results. Complicated RD, macula-involving RD, ellipsoid line disruption in OCT and scleral buckling combined with VPP were prognostic factors for a worse visual outcome.
