Observational Prospective Monocentric Study Evaluating "Sweeper" Use During Epiretinal Membrane Surgery

Detailed Summary

Epiretinal membrane (ERM) is a pathological phenomenon requiring surgery when vision is altered. ERM surgery requires ERM peeling, then active internal limiting membrane (ILM) peeling if it is not spontaneously peeled with ERM. Initiation of peeling is very delicate and can lead to micro scotoma when realized with microscopic forceps. The Sweeper is a microscopic tool with a soft silicon tip covered with diamond dust which allows peeling initiation without retina prehension. It may reduce retinal trauma and visual sequelae. Purpose of our study is to evaluate use of sweeper during 20 ERM surgeries. The investigator will compare microperimetry before surgery versus those after 1 month (M1) and 3 months (M3), and measure difference of number and depths of micro scotoma. The investigator will note: number of forceps uses if sweeper is inefficient and all areas of sweeper use to correlate them with micro scotoma. The investigator will evaluate visual and optical coherence tomography improvement after surgery.
