Eight-year follow-up of central serous chorioretinopathy with and without laser treatment.

A long-term retrospective study was conducted on two groups of patients affected with typical central serous chorioretinopathy (CSCR). One group was not treated and the other was treated by direct argon laser photocoagulation. CSCR shows a long-term good prognosis of visual acuity. The visual acuity of laser-treated eyes improves significantly (P less than or equal to 0.05), particularly in single focus cases (P less than or equal to 0.01). Unfortunately, these results cannot be statistically compared to the natural course of the non-treated patients because of the initial inhomogeneity of the two groups. Laser treatment did not produce any long-term complications. The recurrence rate in treated and untreated eyes was similar.
