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

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. PATIENT CONSENT: Written consent to publish this case has not been obtained.
