Abstract:
Objective To assess the safety and efficacy of subthreshold micropulse yellow laser (577 nm) in the treatment of chronic central serous chorioretinopathy with foveal leakage.Methods This was a prospective study of 12 patients (12 eyes) with chronic central serous chorioretinopathy (CSC).All patients had been treated using multiple spots of subthreshold micropulse yellow laser at 577 nm with a duty cycle of 5％ over areas of focal and diffuse leakage.And lweeks,1 months,3 months,and 6 months after treatment,the best corrected visual acuity (BCVA),central macular thickness (CMT) and reduction in subretinal fluid (SRF) were recorded.Results The mean BCVA measured at 6 months after laser treatment was 0.19 ±0.11,which was in comparison to 0.27 ± 0.08 before laser treatment,and the difference was statistically significant (P =0.016).The mean CMT was significantly reduced from (432.42 ±134.17) μm before laser treatment to (248.75 ±36.06) μm after 6 months (P =0.002).The mean SRF height was significantly decreased from (213.58 ± 132.60) μm at baseline to (17.25 ±21.90) μm (P =0.002).At the last follow-up,the SRF had disappeared completely in 6 out of 12 eyes,but there were still 6 eyes suffering from SRF.There was no evidence of retinal or choroidal damage during 6-month follow up.Conclusion Subthreshold micropulse yellow laser (577 nm) is an effective treatment option for chronic CSC with foveal leakage.
