[Electroretinography findings in the other eye in patients with central retinal vein occlusion]

ERG assessment in 32 patients with recent OVCR was done over the period of 6 years. The aim was to check the hypothesis whether ERG values in the affected and "healthy" eye of the same patient are same. The control group consisted of patients of the same age but without eye disease. Scotopic "b" wave and photopic b/a ratio, known as indicators of oxygenation of the retina, were studied. In bs wave and b/a ratio the statistically significant difference between the group with OVCR and the other groups was found. Other groups showed no significant differences. The hypothesis that OVCR associated with a systemic disease is necessarily accompanied with changes in the other eye, has been challenged. However, the safety of the other eye is not absolute.
