The Evaluation of Prognostic Factors after Vitrectomy for Lamellar Macular Hole Using Optical Coherence Tomography

Purpose: To evaluate the prognostic factors that predict visual outcome after vitrectomy for lamellar macular hole using optical coherence tomography (OCT). Methods: This study included 26 eyes that underwent pars plana vitrectomy, epiretinal membrane removal, and internal limiting membrane peeling for lamellar macular hole. The maximum parafoveal thickness, maximum height and diameter of lamellar macular hole, maximum height and diameter of intraretinal splitting, thinnest foveal floor thickness, and inner segment/outer segment disruption length on preoperative OCT image were investigated for prognostic factors that predict visual outcome. Results: The mean follow-up period was 32.2 months and the mean best corrected visual acuity improved significantly after vitrectomy from log MAR 0.47 ± 0.32 to log MAR 0.23 ± 0.23. The postoperative visual acuity correlated significantly with preoperative visual acuity, thinnest foveal floor thickness and inner segment/outer segment disruption length, but not with maximum parafoveal thickness, maximum height and diameter of lamellar macular hole and maximum height and diameter of intraretinal splitting. Conclusions: The thinnest foveal floor thickness and inner segment/outer segment disruption length on preoperative OCT image were significant prognostic factors.J Korean Ophthalmol Soc 2014;55(12):1853-1859
