[The relation between retinal venous occlusions and glaucoma]

The association of the open-angle glaucoma and the retina venous occlusion constitutes an aggravating factor, the two affections influencing to each other. The study of a number of 168 venous obstructions of the retina, 56% of which being obstruction of the central vein and 44% of ramus, have evaluated appearing as edematous capillaropathy for 36% cases, ischemic capillaropathy for 44% and mixed forms for 20% ones. The retina venous occlusions have evaluated for 70% for masculine gender and 30% for feminine. From all the predisposed affections the hypertension and arteriosclerosis were for 58% all over the cases; dyslipidemias for 15%; hypercholesterolemia for 11%, diabetes for 8%. In the occlusion of the venous ramus the opened angle glaucoma, that has preceded thrombosis, was at the same frequency as for the general population, while in the obstruction of the central vein, the opened angle glaucoma has preceded thrombosis for 18% of all the cases, so it may be considered as a favourable factor by slowing down the sangvin flux. The opened-angle glaucoma hasn't influenced the appearing of the retina thrombosis. The second neurovascular glaucoma, an irreducible complication of the ischemic capillaropathy was for 22% of the studied cases. During the presence of a retina venous thrombosis is necessary a systematic examinations of the ocular tension, for finding an opened-angle glaucoma pre-existed to thrombosis.
