Özet

Objectives: Evaluate the efficacy of chorioretinal venous anastomosis in patients with nonischemic retinal vein occlusions with progressive visual loss and to concentrate on complications. Design: Case series of 6 patients, retrospective study. Six patients with nonischemic central retinal vein occlusions and progressive visual loss. Laser photocoagulation was performed to create a chorioretinal venous anastomosis to be able to supply venous blood to the choroid, bypassing the occlusion, Visual acuity, funduscopic appearance and fluorescein angiographic appearance were determined. Results: Two patients showed a chorioretinal anastomosis (33%), whereas in the other 4 patients the anastomosis could not be created. Yet 1 patient consequently had a neovascular tuft under the laser site. These new vessels caused minor vitreous hemorrhage and a tractional membrane which regressed after 10 months. Conclusion: The utilization of a chorioretinal venous anastomosis by laser as a therapeutic modality should be further questioned and thoroughly evaluated and caution must be exercised to avoid vision-threatening complications.
