Aim To  eveluate  the  therapeutic  effect of 532  laser  improved grid　pattern  photocoagulation  treatment　for　central serous choriretinopathy　without   fluorescein leakage

Methods  For the past  three  years , 56 cases with central serous choriretinopathy　without   fluorescein leakage  in  our  department  were  divided  into  two  groups , the  treatmennt  group (32 patients 32 eys ) and  the  control  group ( 24 cases , 24 eyes ). Patients in the  treatmennt  group were treated by 532 laser  photocoagulation   the  control  group were observed only.

RESULTS  After 532 laser treatment, the mean visual acuity and the edema of macular was improved significantly in treatmennt  group.

CONCLUSION  532  laser  improved grid　pattern  photocoagulation treatment　for　central serous choriretinopathy　without   fluorescein leakage seems to be safe and effective.
