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.
Observation:
We describe SS-OCT and OCT-angiography findings in a 30-year-old patient with CO. The best visualization of the choroid allows even more precise analysis beyond the identification of classical structures of trabecular bone and denser cortical bone. OCT-Angiography show in this case a quiescent choroidal neovascularization without exudation on B-scan OCT.
Conclusions And Importance:
SS-OCT and OCT-angiography allow a nearly histological description of choroidal osteoma.
