Circumscribed choroidal hemangioma: Clinical features and outcomes by age category in 458 cases.

Purpose: To investigate features and outcomes of circumscribed choroidal hemangioma by patient age.

Methods: Retrospective review of circumscribed choroidal hemangioma from 3/29/1967-6/4/2018 based on age at presentation (≤20 vs. >20-50 vs. >50 years).

Results: There were 458 circumscribed choroidal hemangiomas diagnosed at mean age (13 vs. 41 vs. 64 years, p  < 0.001). The youngest age group had worse presenting visual acuity (20/400 vs. 20/150 vs. 20/100, p  < 0.001), larger tumor basal diameter (13.5 vs. 6.6 vs. 6.2, p  < 0.001), greater tumor thickness (5.8 vs. 3.1 vs. 2.9, p  < 0.001), closer distance to foveola (0.5 vs. 1.4 vs. 1.2, p  = 0.03), and greater extent of subretinal fluid (4 quadrants, 26% vs. 8% vs. 2%, p  < 0.001). The youngest patients were less likely to be treated with primary observation (39% vs. 39% vs. 56%) or photodynamic therapy (10% vs. 27% vs. 22%) and more likely to be treated with plaque radiotherapy (26% vs. 6% vs. 3%) or external beam radiotherapy (13% vs. 1% vs. 0%) ( p  < 0.001). The youngest patients required greater total number of treatments (mean 4 vs. 2 vs. 1, p  < 0.001). At mean follow-up (44 vs. 68 vs. 60 months, p  = 0.37), the youngest patients had worse visual acuity (20/400 vs. 20/200 vs. 20/100, p  = 0.03), but no difference in visual acuity loss of 3 or more Snellen lines (27% vs. 13% vs. 16%, p  = 0.55).

Conclusion: Younger patients (≤20 years) with circumscribed choroidal hemangioma present with worse visual acuity and larger, more posterior tumors. Future studies are needed to improve early detection and treatment for this subgroup of patients.
