Abstract :
Data suggest that the multifocal electroretinography (mfERG) may have a role in the
assessment of patients with central retinal vein occlusion (CRVO). To explore the mfERG responses in
patients with CRVO. mfERG responses were recorded at 61 discrete retinal locations from both eyes of
25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. The latencies and
amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to fixation, and
grouped central and peripheral rings of involved eyes were compared with values obtained from 13
normal fellow eyes of these subjects. The mfERG responses obtained from eyes with CRVO were
significantly different from those derived from the fellow eye, especially when the rings are grouped as
central and peripheral. mfERG is a new, safe, non-invasive, and quick investigative tool to assess retinal
function. Our results suggest that mfERG could be a useful electrophysiologic test in clinical evaluation
and determination of the severity of underlying ischemia in patients with retinal vein occlusion. Further
studies are needed to evaluate its role as a prognostic method to determine which eyes are prone to
serious complications. This is the first report of mfERG results in Iran.
