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

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.
