Abstract:
This is an observational case series of four cases of choroidal hemangioma. All cases underwent OCT angiography with swept source OCTA (Topcon DRI OCT Triton plus) 6 mm * 6 mm protocol. OCTA at the level of large choroidal vessels demonstrated peculiar vascular pattern in all four eyes. Patterns observed were bag of worms, spaghetti like and vessels with terminal bulbs. In eye with diffuse choroidal hemangioma comparison of choroidal vascular pattern with the contralateral eyes showed significant difference in the vascular architecture. OCTA is an excellent non invasive tool in assessing the choroidal vascular pattern in eyes with choroidal hemangioma.
