Abstract

The purpose of this case series was to evaluate the features of circumscribed choroidal hemangioma on pseudocolor ultrawide-field (UWF) retinal images simulating choroidal melanoma and compare it to fundoscopic appearance. All four patients underwent full ophthalmological examination, including dilated fundus examination, ultrasonography, and UWF imaging (UWFI). All circumscribed choroidal hemangioma appeared clinically as orange-red choroidal lesions which were echodense with regular internal structure on ultrasonography. All lesions appeared green-grey in color on pseudocolor UWFI. Pseudocolor UWFI of circumscribed choroidal hemangioma represents distortion of true color appearance and may simulate choroidal melanoma. [Ophthalmic Surg Lasers Imaging Retina 2023;54:292-296.].
