Abstract

PURPOSE:

To investigate the predictive value of the cone b-wave implicit time in the 30-Hz flicker electroretinogram for rubeosis in the acute phase of central retinal vein occlusion.

METHODS:

In a prospective study, 25 patients (25 eyes) with a central retinal vein occlusion of less than 14 days' duration were examined with electroretinography and followed up for a minimum of 18 months.

RESULTS:

The cone b-wave implicit time in the eyes that developed rubeosis (n = 11) was more than 37.1 milliseconds and in the eyes that did not develop rubeosis (n = 14), less than 37 milliseconds (P < .00001).

CONCLUSION:

The cone b-wave implicit time in the 30-Hz flicker electroretinogram is a good predictor of rubeosis at an early stage in eyes with central retinal vein occlusion.
