Transient angle-closure glaucoma after retinal vein occlusion. Report of two cases.

Glaucoma may be a contributory factor in the aetiology of retinal vein occlusion or may result from this condition. When glaucoma occurs secondary to retinal vein occlusion, it is usually considered to be due to vascularization of the anterior chamber angle and closure of the angle by goniosynechiae (Duke-Elder and Dobree, I967; Ballantyne and Michaelson, 1970). The two cases of retinal vein occlusion reported below exhibited marked shallowing of the anterior chamber, pupillary block, and transient angle-closure glaucoma, without vascularization of the angle.
