The therapeutic efficacy of laser-induced chorioretinal venous anastomosis on macular edema of non-ischemic retinal vein occlusion / 中华眼底病杂志

ABSTRACT

Objective To evaluate the therapeutic effect of laser induced chorioretinal venous anastomosis on macular edema of non ischemic retinal vein occlusion. Methods Thirty seven eyes of 37 cases of non ischemic retinal vein occlusion received the treatment of laser induced chorioretinal venous anastomosis and were followed up for 6～12 months. All affected eyes underwent the clinical examinations of visual acuity, ocular fundus photography, fundus fluoreceine angoigraphy (FFA) and light sensitivity of central 5 degree of the retina, and the pre and post operative clinical materials were analyzed. Results Successful chorioretinal venous anastomosis was formed in 18 eyes (48.6%) within 2 months after laser photocoaglation, with the mean best improved corrected visual acuity of (4 25?0 46) lines, while the mean best corrected visual acuity of the other 19 eyes with unsuccessful anastomosis decreased (0 20?0 54) lines ( P
