Un deficit endogène en monoxide d'azote est un facteur aggravant lors d'une occlusion veineuse rétinienne

PURPOSE: Following retinal branch vein occlusion (b.v.o.), the arteriole crossing the occluded territories is often constricted. This constriction persists up to several weeks and is correlated with the development of extended territories of non-perfused capillaries. We present here results of an investigation supporting the hypothesis that decrease in the production of nitric oxide (NO) accounts…
