OBJECTIVE: To compare the clinical features of primary vs secondary retinal vasoproliferative tumors (VPTs). METHODS: Retrospective case series of 334 tumors in 295 eyes of 275 patients. RESULTS: Of 275 patients with VPT, 41% (n = 113) were male and 59% (n = 162) were female, with a mean age of 44 years at presentation. Primary VPT occurred in 80% (n = 219) and secondary VPT, in 20% (n = 56) of patients. Secondary VPT (n = 67) occurred in eyes with retinitis pigmentosa (n = 15, 22%), pars planitis (n = 14, 21%), Coats disease (n = 11, 16%), previous retinal detachment surgery (n = 8, 12%), idiopathic peripheral retinal vasculitis (n = 4, 6%), familial exudative vitreoretinopathy (n = 3, 4%), and others (n = 12, 18%). The mean interval between diagnosis of underlying ocular condition and secondary VPT was 160 months. Statistically significant differences (P < .05) in clinical features (primary vs secondary VPTs) included mean age at presentation (46 vs 38 years), visual symptoms (74% vs 87%), poor visual acuity worse than 20/200 (15% vs 28%), bilaterality (4% vs 20%), multifocality (5% vs 15%), postequatorial tumor location (20% vs 33%), tumor basal dimension (6 vs 7 mm), anterior chamber cells (16% vs 30%), and vitreous cells (19% vs 48%). CONCLUSIONS: Retinal vasoproliferative tumor can be primary (80%) or secondary (20%). Compared with primary VPT, secondary VPT is more often bilateral, multiple, and larger and occurs at an earlier age associated with poorer visual acuity.
