Choroidal Osteoma Deossification Visualized by Enhanced Depth Imaging Spectral-Domain Optical Coherence Tomography

Area of Science:

• Ophthalmology
• Medical Imaging
• Oncology

Background:

• Choroidal osteoma (CO) is a rare, benign ossifying choroidal lesion.
• While generally having a good visual prognosis, deossification of CO can lead to vision loss.
• This vision loss is often attributed to photoreceptor degeneration overlying the lesion.

Observation:

• A case study of an elderly male with choroidal osteoma is presented.
• The patient was monitored over a 3-year period using enhanced depth imaging optical coherence tomography (EDI-OCT).
• Tumor deossification and overlying photoreceptor atrophy were observed during the follow-up period.

Findings:

• The study observed tumor deossification and photoreceptor atrophy in a case of choroidal osteoma.
• Despite deossification, visual acuity was preserved due to the lesion's noncentral location.
• Enhanced depth imaging optical coherence tomography (EDI-OCT) was instrumental in monitoring these changes.

Implications:

• Regular EDI-OCT screening is recommended for patients diagnosed with choroidal osteoma.
• Early detection of tumor deossification can help identify patients at risk of vision loss.
• Proactive monitoring may allow for timely interventions to preserve visual function in CO patients.
