Abstract

AimTo describe the vascular features of choroidal tumors using enhanced depth imaging (EDI), optical coherence tomography (OCT), and OCT-angiography.MethodsIn this prospective study, we evaluated 116 Caucasian patients with choroidal tumors (60 eyes with choroidal nevi, 40 with choroidal melanoma, 6 with choroidal hemangioma, 2 with optic disc melanocytoma, 6 with choroidal osteoma, and 2 with retinal metastases). Patients underwent a complete ophthalmic examination including bulbar echography, EDI-OCT, OCT-angiography, and multicolor imaging. Sixteen patients also underwent fluorescein and indocyanine angiography.ResultsThe left eye was more involved than the right eye. The mean tumor thickness was 1.23±0.17 mm in the 60 eyes with choroidal nevi; 2.75±0.83 mm in the 40 eyes with choroidal melanoma; 3.28±0.78 mm in the 6 eyes with retinal angioma; 2.02±0.001 mm in the 2 eyes with optic disc melanocytoma; 2.40±0.31 mm in the 6 eyes with choroidal osteoma; and last, 3.49±0.001 mm in the 2 eyes with retinal metastases. OCT-angiography showed: (i) a lack of blood flow in the outer retinal layer (ORL) and a normal choroid capillary layer in choroidal nevi and optic disc melanocytomas; (ii) a lack of blood flow in the ORL of choroidal metastases; and (iii) a dense irregular vascular network in the ORL and choroid capillary layers of choroidal melanomas, choroidal hemangiomas, and choroidal osteomas.ConclusionsOCT-angiography is a noninvasive reliable method with which to evaluate the vascularization of small choroidal tumors and may improve the diagnosis of these tumors
