Abstract
Purpose: :
To describe the autofluorescence features of choroidal hemangioma
Methods: :
Standard fundus photography and autofluorescence (AF) photography (580 nm excitation, 695 nm barrier filter) were performed on all patients. Clinical features were correlated with autofluorescence features.
Results: :
There were 27 eyes with circumscribed choroidal hemangioma (CCH) and 7 eyes with diffuse choroidal hemangioma (DCH). The mean patient age was 53 years for CCH and 15 years for DCH. Intrinsic AF of untreated CCH was generally isoAF (n=7, 58%) and for treated CCH was hypoAF (n=15, 100%). Extrinsic AF of CCH disclosed hyperAF (orange pigment and fresh subretinal fluid) and hypoAF (RPE hyperplasia, fibrous metaplasia, and atrophy). Intrinsic AF of untreated DCH was generally hypoAF (n=2, 67%) and for treated DCH was hypoAF (n=3, 75%). Extrinsic AF of DCH was similar to CCH.
Conclusions: :
Choroidal hemangioma shows little intrinsic autofluorescence. Overlying orange pigment and fresh subretinal fluid show hyperAF and RPE hyperplasia and atrophy show hypoAF.
