    Area of Science:

    • Ophthalmology
    • Oncology

    Background:

    • Choroidal osteomas are rare, benign bone tumors originating in the choroid layer of the eye.
    • They can present with visual disturbances, particularly in young individuals.

    Observation:

    • Four healthy young women presented with visual symptoms attributed to choroidal osteomas.
    • Ophthalmoscopic examination revealed elevated, yellow-white tumors with distinct borders, overlying pigmentary changes, and neovascularization.
    • Ancillary tests included a positive 32P test, angiography showing characteristic hyperfluorescence, dense ultrasound findings, and visualization on X-ray and CT scans.

    Findings:

    • Histopathologic confirmation was obtained via enucleation in one case, verifying the presence of bone tissue.
    • Imaging studies consistently demonstrated the tumors' dense, bony consistency, impacting orbital tissue visualization.

    Implications:

    • Early and accurate diagnosis of choroidal osteomas is crucial for managing visual symptoms.
    • Multimodal imaging and specialized tests aid in differentiating these tumors from other choroidal lesions.
    • Understanding the imaging characteristics is key for appropriate patient management and prognosis.
