Transpupillary thermotherapy in the treatment of central serous chorioretinopathy

Abstract

A 40-year-old man had persistent central serous chorioretinopathy at the foveal region for 20 months. The pretreatment best-corrected visual acuity was 0.3. The leaking point was close to the fovea, making the use of argon laser photocoagulation treatment unsafe. Transpupillary thermal therapy with diode laser (power setting = 120 mW, spot size = 1.2 mm, and duration = 60 seconds) was performed to cover the whole detached area. The subretinal fluid decreased 1 week later. Fluorescein angiography 2 months later revealed neither further leakage nor any subretinal fluid. After 3 months of follow-up, best-corrected visual acuity improved to 0.4. Transpupillary thermal therapy may be a useful alternative for the treatment of chronic, persistent central serous chorioretinopathy at the fovea.
