Electroretinographic findings versus fluorescein angiographic appearance of the retina in patients with ischaemic and non-ischaemic central retinal vein occlusion.

We compared the fluorescein angiographic and electroretinographic findings in 39 eyes of 37 patients with a central retinal vein occlusion. We proved that the flash-electroretinogram is a clinically useful test to differentiate the ischaemic type of central retinal vein occlusion from the non-ischaemic type.
