PURPOSE: To assess treatment with a 577-nm subthreshold micropulse laser (SML) in patients with chronic central serous chorioretinopathy (cCSC). METHODS: This retrospective study included 38 patients treated with a 577-nm SML (Supra Scan; Quantel Medical) for cCSC. We included a subgroup of 18 patients with persistent subretinal fluid (SRF) after photodynamic therapy (PDT). Assessment included visual acuity (VA), central retinal thickness (CRT) and resolution of SRF. RESULTS: At the last follow-up (mean 5 months), 74% of patients responded to therapy. The CRT decreased after treatment (mean CRT -115 microm, p < 0.001) and VA improved (mean logMAR -0.06, p = 0.039). No laser burns were detected with any imaging modality. In the subgroup of patients resistant to PDT, 61% of patients responded to therapy with a decrease in CRT (mean CRT -75 microm, p = 0.019). CONCLUSIONS: The 577-nm SML is an effective treatment for cCSC even in patients without sufficient improvement after PDT.
