Choroidal Macrovessel Diagnosed on Multimodal Imaging, including Swept-Source Optical Coherence Tomography Angiography

Abstract

Choroidal macrovessel (CM) is a rare anomalous vascular lesion in the choroid. In this case report, we describe a 72-year-old Caucasian man diagnosed with an incidental heavily branching CM in the macula of his right eye based on multimodal imaging, including enhanced depth imaging optical coherence tomography (OCT), swept-source OCT angiography, and indocyanine green angiography. Multimodal imaging is valuable in demonstrating the distinctive appearance of this entity and differentiating it from more vision-threatening differential diagnoses, such as ophthalmomyiasis interna, choroidal neoplasms, retinochoroidal anastomosis, and inflammatory conditions.
