<br /> To assess visual and anatomic outcomes after epiretinal membrane (ERM) peeling surgery in patients with previous complex rhegmatogenous retinal detachment (RD) repair.
<br /> Charts of patients who had undergone epiretinal membrane (ERM) peeling after prior multiple rhegmatogenous retinal detachment (RD) repair surgeries were reviewed. Snellen best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) characteristics at pre- and post-op visits (1, 3, 6, and 12 months) were analyzed. Visual acuities (VA) were converted to ETDRS letter scores in order to calculate the mean and median visual improvement at each time point. OCTs were analyzed for the presence and location of fluid and retinal layer appearance.
<br /> Twenty one patients who had been treated at the Bascom Palmer Eye Institute from January 2005 to December 2011 were identified. The mean number of retinal detachment repairs was 2.33 (range 2-5). Mean BCVA was 18.63 (SD=25.68) letters at pre-op and 19.00 (SD=19.63, P=0.96), 22.72 (SD=24.60, P=0.73), 15.55 (SD=19.43, P=0.56), and 19.29 (SD=25.69, P=0.74) letters at 1, 3, 6, and 12 months, respectively. Mean central foveal thickness (CFT) changed from 338.50 (SD=27.58) microns at pre-op to 728.50 (SD=277.89, P=0.27), 538.00 (SD=179.21, P=0.23), and 395.00 (SD=349.01, P=0.90) at 3, 6, and 12 months, respectively. Mean macular volume changed from 9.34 mm3 (SD=4.62) at pre-op to 13.82 (SD=3.60, P=0.10), 12.04 (SD=1.85, P=0.13), and 8.88 (SD=6.39, P=0.98) at 3, 6, and 12 months, respectively. No OCT data at 1 month was available.
<br /> In this pilot study, visual acuity and OCT appearance did not improve significantly after ERM peeling in patients with multiple prior rhegmatogenous retinal detachment repairs. Given the complexity of pathology and limited number of patients, further studies are warranted to better understand anatomic and visual outcomes after ERM peeling in this patient population.
