Official Title: Evaluation of the Cone Outer Segment Tips Line After Epiretinal Membrane Surgery

Brief Summary: The recovery of the cone outer segment tips (COST) line after epiretinal membrane (ERM) surgery using spectral-domain optical coherence tomography (SD-OCT) was assessed.

Detailed Summary: Epiretinal membrane (ERM) may cause decreased central vision or metamorphopsia. Pars plana vitrectomy with membrane peeling has become the standard treatment for epiretinal membrane. However, visual recovery or symptomatic relief is not always satisfactory in all eyes despite successful membrane removal. Spectral domain optical coherence tomography (SD-OCT) is a non-invasive imaging device for various vitreoretinal diseases. Cone outer segment tips (COST) line is a line observed between IS/OS line and RPE in SD-OCT. The investigators examined the correlation of visual acuity and the recovery of photoreceptor layer after ERM surgery, taking COST line into account as a new parameter

Current Primary Outcome: best-corrected visual acuity [ Time Frame: one year ]

Original Primary Outcome: Same as current

Current Secondary Outcome: Integrity and defect length of the photoreceptor layer detected by spectral-domain optical coherence tomography [ Time Frame: one year ]

Original Secondary Outcome: Integrity of the photoreceptor layer detected by spectral-domain optical coherence tomography [ Time Frame: one year ]
