Contribution of swept-source OCT-angiography in analysis of choroidal osteoma and its quiescent neovascular complications: A case study

American Journal of Ophthalmology Case Reports, 2020
Purpose: Choroidal osteoma (CO) is a rare benign tumor of the choroid. Improvements in Optical Coherence Tomography (OCT) technologies, notably swept-source (SS), enables a better visualization of the choroid with deeper signal penetration in the tissues.
