Introduction: Well established pathognomonic Optical Coherence Tomography (OCT) and Optical Coherence Tomography Angiography (OCTA) findings for choroidal tumors are lacking.

Purpose: To evaluate spectral domain OCT SD-OCT using choroidal enhancement technique (EDI) and more recently OCTA in detecting diagnostic criteria of choroidal tumors

Methods: A multicenter observational study was conducted between 2007 and 2017 for recently diagnosed choroidal tumors using OCT and OCTA technology.

Qualitative analysis included the overlying retina, tumor surface and internal features, light penetration within the mass (intra lesion reflectivity) by OCT, and surrounding blood vessel changes by OCTA, in addition to discrimination from surrounding choroidal tissue.

Results: A total of 50 eyes were identified and included for analysis. These were clinically classified into: choroidal metastasis, choroidal hemangioma, choroidal melanoma, choroidal nevus.

SD-OCT identified precise criteria for each tumor type, and distinguished tumor landmarks from the surrounding normal choroid. OCTA highlighted various changes to the surrounding and overlying blood vessels and was performed on a total of 12 eyes.

Conclusion: SD-OCT and OCTA are efficient in detecting pathognomonic criteria for different types of choroidal tumors and can be used as a non-invasive diagnostic tools.
