Comparison of 577 nm Laser Micropulse Mode and 532 nm Laser Photocoagulation in the Treat-ment of Patients with Central Serous Chorioretinopathy
[Objective]To compare the efficacy of 577 nm laser micropulse mode and 532 nm laser photocoagulation in the treatment of central serous chorioretinopathy(CSC).[Methods]Sixty patients(60 eyes)with CSC diagnosed by fluorescein fundus angiography,indocyanine green angiography and optical coherence tomography(OCT)were selected from September 2021 to August 2023 in our hospital.They were voluntarily divided into the observation group(receiving 577 nm laser micropulse mode treatment)and the control group(receiving 532 nm laser photocoagulation treatment),with 30 cases(30 eyes)in each group.The best corrected visual acuity(BCVA),central macular thickness(CMT)and subfovea choroidal thickness(SCT)and subretinal fluid(SRF)were compared between the two groups before treatment and at 1 month,3 months and 6 months after treatment.[Results]Compared with before treatment,the BCVA,CMT and SRF heights of both groups were improved(P＜0.05)after 1 month of treatment,while SCT was not significantly improved(P＞0.05).After 3 months of treatment,SCT decreased in both groups(P＜0.05).There was no significant difference in BCVA,CMT and SRF height between the two groups at 1 month,3 months and 6 months after treatment(P＞0.05).There was no significant difference in SCT at 1 month and 6 months after treatment between the two groups(P＞0.05).The SCT of the observation group was lower than that of the control group at 3 months after treatment,and the difference was statistically significant(P＜0.05).There was no significant difference in SRF absorption rate at 1 month,3 months and 6 months after treatment between the two groups(P＞0.05).[Conclusion]Both 577 nm laser mi-cropulse mode and 532 nm laser photocoagulation can improve visual acuity and reduce the height of CMT and SRF in CSC patients after 1 month.Both laser treatments reduced SCT after 3 months,but the reduction was more pronounced in the 577 nm laser micropulse mode.
