Purpose: To evaluate the effectiveness of low-dose aspirin for the treatment of central serous chorioretinopathy (CSCR).
Patients and methods: Patients with classical or multifocal CSCR were treated with aspirin 100 mg per day orally for 1 month followed by 100 mg on alternate days for 5 months. Treated patients were compared with historic controls consisting of patients with classical or multifocal CSCR previously followed up at our institution.
Results: Mean visual acuity in the group treated with aspirin started to improve after the first week of therapy and continued to improve throughout the following 3 months. Visual recovery was slower in the untreated control group than in the treated group and achieved better visual acuity between the first and third month from the onset of the disease. There were no adverse events related to the administration of aspirin.
Conclusion: The results indicate that treatment with low-dose aspirin may result in more rapid visual rehabilitation with fewer recurrences in patient with CSCR compared with untreated historic controls. The effectiveness of treatment with aspirin supports our hypothesis regarding the role of impaired fibrinolysis and increased platelet aggregation in the choriocapillaris in the pathogenesis of CSCR.
