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 description

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
