Krypton and argon laser photocoagulation for central serous chorioretinopathy

Abstract

Based on medical records, the authors divided 86 eyes of 84 patients with central serous chorioretinopathy with serous detachment of the macula and retinal pigment epithelial leakage on fluorescein angiography into three groups: no laser treatment (45 eyes), argon laser treatment (26 eyes), and krypton laser treatment (15 eyes). One or more episodes of recurrence developed during the follow-up period in 10 untreated eyes (22%), 9 argon-treated eyes (35%), and 0 krypton-treated eyes. The difference in recurrence rate between argon- and krypton-treated eyes was statistically significant. The findings suggest that whenever laser treatment is indicated, krypton red laser photocoagulation may reduce the incidence of recurrence in eyes with central serous chorioretinopathy.
