A prospective follow-up study of panretinal photocoagulation in preventing neovascular glaucoma following ischaemic central retinal vein occlusion

Fifteen consecutive eyes with central retinal vein occlusion (CRVO) and extensive capillary non-perfusion were treated by panretinal photocoagulation using argon laser. Of these eyes six had chronic glaucoma and one had acute angle-closure glaucoma when first seen. One developed neovascular glaucoma before treatment. After photocoagulation iris new vessels appeared in two eyes with preexisting glaucoma. In one case the new vessels later regressed without further treatment. The prevalence of neovascular glaucoma was considerably less than has been reported in untreated eyes with ischaemic-type CRVO. Poor dilatation of the pupil due to pre-existing glaucoma, cataract and/or massive retinal oedema put a limit on the extent of treatment.
