Multifocal ERG in retinal detachment surgery
Purpose:
The main purpose of this study is to evaluate the visual function of eyes operated on for rhegmatogenous retinal detachment.
Methods:
Fifteen patients were studied suffering from peripheral retinal detachment treated with the Lincoff-Custodis method. Visual field was tested with the Humphrey Field Analyzer and the analyzer program 30-2, which scanned a 0-30 degrees field. The multifocal ERG was recorded with the VERIS III (Visual Evoked Imaging System, Tomey, Nagoya, Japan).
Results:
There was great loss of retinal response densities in the area of retinal detachment (1.3 +/- 0.7 nV/deg2). However, a decrease in retinal response densities was also recorded in the reattached retina (6.90 +/- 0.7 nV/deg2).
Conclusions:
MFERG is an objective tool for monitoring the functional abnormalities affecting the vision of eyes operated for retinal detachment.
