It is not easy to predict which patients with a central retinal vein occlusion will develop rubeosis and which will not. We have compared two methods for doing so, fluorescein angiography and full-field electroretinogram (ERG). Our aim was to improve our possibilities for predicting rubeosis in patients with central vein occlusion.
32 patients with a central retinal vein occlusion with a duration of less than 14 days were included in the study. Fluorescein angiography and ERG were performed in all patients. The fluorescein angiograms were studied by two independent examiners in a masked mode. The patients were then followed for at least one year.
Development of rubeosis in patients with central retinal vein occlusion could be predicted by fluorescein angiography in 82% of the patients and with ERG in 94% of the patients. The non-ischemic central retinal vein occlusions were identified in 62% by fluorescein angiography and in 100% with ERG. Fluorescein angiography misjudged 9 patients 28%, whereas ERG only misjudged 1 patient, 3%.
ERG seems to be a better method for predicting the prognosis in central retinal vein occlusion than fluorescein angiography.
