Choroidal Osteoma Deossification Visualized by Enhanced Depth Imaging Spectral-Domain Optical Coherence Tomography
Choroidal osteoma (CO) is a rare, benign ossifying lesion of the choroid found in otherwise healthy patients. Although associated with good visual prognosis, tumor deossification in choroidal osteoma has been linked with vision loss, presumably due to overlying photoreceptor degeneration. Here the authors present a case of CO in an elderly male demonstrating tumor deossification and photoreceptor atrophy during a 3-year follow-up using enhanced depth imaging optical coherence tomography (EDI-OCT). Visual acuity was maintained due to the tumor's noncentral location. Patients with CO should undergo regular imaging with EDI-OCT to screen for tumor deossification and impending vision loss.
