There is one clinical trial.
Purpose: To examine the genotypes associated with the peripheral retinal phenotypic features in patients with age-related macular degeneration documented with wide-field imaging. Design: Clinic-based case series study in Croatia. Participants: 160 patients >50 years of age known to have early or advanced AMD and 150 subjects >50 years of age without known AMD (controls) Methods: Both groups of patients were examined with ophthalmoscopy and OCT to confirm their classification. Posterior and peripheral fundus features were documented with Optos wide-field imaging (Optos P200MA, Optos Plc, Dunfermline, Scotland) and graded. DNA was extracted from blood samples and gene polymorphisms were evaluated for complement factor H (CFH) rs1061170 and rs1410996, age-related maculopathy susceptibility (ARMS2) rs10490924, high temperature requirement factor A1 (HtrA1) rs11200638, complement factor B (CFB) rs4151667 and rs641153, complement factor 2 (C2) rs9332739 and rs547154 and complement factor 3 (C3) rs2230199.
