Choroidal Osteoma: Case Series
Abstract
Purpose To describe the clinical presentation, multimodal imaging findings, and management of patients with choroidal osteoma observed at a tertiary ophthalmic center. Methods A retrospective case series of three patients (four affected eyes) diagnosed with choroidal osteoma at the Kazakh Eye Research Institute, Almaty, Kazakhstan. All patients underwent a comprehensive ophthalmic examination, including best‐corrected visual acuity assessment, fundus photography, B‐scan ultrasonography, optical coherence tomography (OCT), fluorescein angiography (FA), OCT angiography, and computed tomography (CT). Results The patients presented with decreased vision, progressive visual impairment, or vitreous floaters. Choroidal osteoma was identified as a yellowish‐white or orange peripapillary subretinal lesion with well‐defined borders. Multimodal imaging demonstrated characteristic calcified choroidal lesions with high acoustic reflectivity on ultrasonography, hyperdense plaques on CT, and hyperreflective heterogeneous structures on OCT corresponding to cancellous bone architecture. None of the patients demonstrated active choroidal neovascularization at presentation. Associated systemic or inflammatory conditions included systemic lupus erythematosus, retinal vasculitis, and chronic infectious exposure. All patients were managed conservatively with regular follow‐up because of the absence of severe complications requiring intervention. Conclusions Choroidal osteoma is a rare benign…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
