Abstract

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 () 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 (). 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.
