AIMS: The aim of this study is to describe the incidence and characteristics of neovascularization in the fellow eye of patients with retinal angiomatous proliferation (RAP). METHODS: This is a retrospective study conducted on all patients with a diagnosis of unilateral RAP commencing treatment in a single centre between November 2002 and January 2010. Clinical biomicroscopic examination, fluorescein angiography, and if required, indocyanine green angiography, and optical coherence tomography were used to evaluate all patients. RESULTS: In all, 37 patients had a follow-up of ≥1 year, 28 ≥2 years, and 11 ≥3. Patients who developed RAP in the fellow eye were: 2 of 37 (5.4%) within 1 year of follow-up, 4 of 28 (14.2%) within 2 years, and 4 of 11 (36.3%) within 3 years. CONCLUSION: In our case series, the risk of neovascularization in the fellow eye of patients with unilateral RAP increased with time. Approximately one-third of patients with a 3-year follow-up developed a bilateral disease. Our findings warrant further large-scale investigation.
