Pre And Post Operative Multifocal Electroretinogram In Retinal Detachment With Macula Off And Scleral Buckling.

Abstract

Abstract: : Purpose: To demonstrate the changes between pre and post operative multifocal electroretinogram in patients with retinal detachment and macula off. Methods: Multifocal electroretinogram (RETIscan 3.1) was performed with a 61 hexagons pattern in 5 concentric rings separated in two areas: foveolar area was defined as the first and second ring; and outer macula represented by the rest of the rings. The exam was performed preoperative and 1 month postoperative, with ophthalmologic evaluation and best corrected visual acuity (BCVA). We compare the results with the fellow eye. Results: Fourteen patients were included. Mean age was 44.90 years. Time of retinal detachment was 37.5 days. Affected eye initial BCVA was +2.08 logMAR. The fellow eye had a 0.61 logMAR BCVA. The improve on b–wave amplitude was statistically significative posterior to scleral buckling in all rings but central one. Differences in implicit time weren’t statiscally significative between the healthy eye and the eye in study in the preoperative and postoperative examination. Conclusions:There is significant improvement in the electrophysiological response of the macula after effective surgical reattachment but in central rings, which could mean tissular sensitivity of foveal area. mfERG could assess retinal physiology after retinal detachment and state visual prognosis.
