[A case of choroidovitreal neovascularization after unsuccessful laser chorioretinal venous anastomosis for central retinal vein occlusion].
BACKGROUND
A case of nonischemic central retinal vein occlusion, which developed severe neovascular complication after unsuccessful laser chorioretinal venous anastomosis is reported.


METHODS
The patient was a 50-year-old man with nonischemic central retinal vein occlusion of the right eye. Two weeks after laser chorioretinal venous anastomosis attempt, closure of the venous segment distal to the anastomotic sites occurred and a choroidovitreal neovascularization developed, so that vitreous surgery was needed 2 months after the laser attempt.


CONCLUSIONS
Laser chorioretinal venous anastomosis should be used only on carefully selected patients, and close follow-up is needed after this treatment.
