Abstract
PURPOSE: To evaluate the long-term results of focal laser photocoagulation and photodynamic therapy (PDT) for treatment of central serous chorioretinopathy (CSC). STUDY DESIGN: Retrospective chart review. METHODS: Sixty-two patients with CSC, thirty-three of whom were treated with focal laser photocoagulation, and 29 with PDT and who were followed up for > 6 months, were enrolled. The focal laser was performed at sites of focal leakage (but not subfoveal leaks) shown in fluorescein angiography. PDT was performed at sites of subfoveal or juxtafoveal focal leakage or not definite focal leakages. Best corrected visual acuity (BCVA), central macular thickness (CMT), resolution of subretinal fluid (SRF) and recurrence were analyzed. RESULTS: The follow-up duration of the focal laser group was 35.2 ± 22.6 and of the PDT group, 46.4 ± 21.5 months. Time to resolution of SRF was 1.8 ± 1.5 months for the focal laser group and 1.2 ± 0.5 months for the PDT group. SRF was rapidly absorbed in the PDT group. In both groups, the CMT was decreased 1 month after treatment. The BCVA improved significantly 1 month after treatment in the focal laser group and 3 months after treatment in the PDT group. However, there was no significant difference in CMT reduction and BCVA improvement between the two groups. It subsequently remained similar for up to 3 years. Ten patients (30.3%) in the focal laser group and three patients (10%) in the PDT group recurred during the follow-up period. CONCLUSIONS: PDT showed early resolution of the SRF compared to focal laser. In CSC patients, both the CMT and BCVA remained stable for 3 years after treatment. After 3 or more years of follow-up, PDT showed a lower recurrence rate than focal laser.
