Purpose. to evaluate contrast sensitivity (cs) changes in acute central serous chorioretinopathy (csc). methods. visual acuity (va),cs,and subretinal fluid (srf) were evaluated monthly for 6 months. treatment was considered at 3 months in case of persistent srf. results. twelve of 20 eyes (60%) had spontaneous srf resolution within 4 months. five of 8 patients with delayed srf resolution received either focal laser or photodynamic therapy. the cs was impaired in all spatial frequencies at baseline. there was a negative correlation between the baseline srf thickness and cs at 3 and 6 cycles per degree (cpd). the cs improved significantly at the time of fluid resolution (p=0.001) and continued to improve in 3 and 6 cpd. the cs at 6 cpd did not recover if compared to a normal fellow eye at 6 months (p=0.018). the cs of 12 cpd at 6 months was superior in the spontaneous resolution group. conclusion. the impaired cs gradually improved as the srf reduced at all spatial frequencies. cs at 3 and 12 cpd continued to improve after complete fluid resolution. despite an excellent final va,the cs at 6 months did not regain its normal value. © 2017 preeyachan lourthai and patama bhurayanontachai.
