Case Reports
Dilation of the minor arterial circle of the iris preceding rubeosis iridis during retinal vein occlusion.
To report in four patients with retinal vein occlusion the presence of biomicroscopically visible circulation in the minor arterial circle of the iris, preceding rubeosis iridis in two cases. ⋯ In patients with ischemic retinal vein occlusion, the clinical finding of a dilation of the minor arterial circle may indicate the necessity of a closer follow-up to make a timely decision on panretinal photocoagulation.
