Abstract

Purpose : To evaluate the subfoveal choroidal thickness of before and after focal laser photocoagulation in the patients with acute central serous chorioretinopathy.

Methods : In this retrospective and comparative study, patients who were treated with focal laser photocoagulation under the diagnosis of acute central serous chorioretinopathy, and whose subretinal fluid was resolved after treatment were enrolled. The patients who were regularly followed up for more than 6 months were included. Best corrected visual acuity(BCVA), subfoveal central choroidal thickness(SCCT) and existence of pigment epithelium detachment(PED) were examined before and after laser photocoagulation. And the height and width of subretinal fluid(SRF) before treatment were also evaluated. The correlations among various parameters were analyzed using spearman correlation analysis, linear regression analysis and paired t-test. We also speculated the age related factors.

Results : Thirty three eyes of thirty three patients were treated with focal laser photocoagulation. The average BCVA was improved from 0.25 ± 0.27 to 0.13 ± 0.21 with statistical significance in logarithm of the minimal angle resolution(LogMAR) scale after treatment(p<0.05). The average thickness of SCCT decreased from 428.8 ± 67.4µm to 405.1 ± 64.1µm with statistical significance after treatment(p<0.01). On the analysis of choroidal thickness, decrease in haller’s layer was significantly related to the decrease in SCCT(p<0.05). PED were observed in 12 eyes before treatment and disappeared after then in 10 eyes. Among the other parameters, there is no significant correlation with SCCT before and after treatment.

Conclusions : We found that focal laser photocoagulationcan reduce the subfoveal choroidal thickness, especially haller’s layer, in the eyes with acute central chorioretinopathy. This study may help understanding the mechanism of focal laser photocoagulation in management of central chorioretinopathy.
