One hundred thirteen cases of tributary retinal vein occlusions were evaluated with none progressing to central vein occlusions. Sixteen patients had open angle glaucoma, or elevated intraocular pressures. Only one patient with macular edema regained a visual acuity of 20/20. More pronounced visual depressions were found with more proximal occlusion sites.
Fourteen patients with macular edema and 30 with vitreous hemorrhages received photocoagulation with improved or stabilized visual acuities being the rule. Photocoagulation also appeared to prevent the development and recurrences of vitreous hemorrhages.
