[Development of retinal vein thrombosis after argon laser photocoagulation (author's transl)].

In this paper 21 cases of branch vein thrombosis and 15 cases of central retinal vein thrombosis treated by argon laser photocoagulation are compared with an untreated control group. The visual prognosis after photocoagulation was no better in the treated group than in the control group. After central retinal vein occlusion, three cases of hemorrhagic glaucoma (20%) were observed in the control group but there was no rubeosis iridis or hemorrhagic glaucoma in the group treated by argon laser therapy.
