Unexplained heterochromia. Intraocular foreign body demonstrated by computed tomography

Area of Science:

• Ophthalmology
• Radiology
• Medical Imaging

Background:

• Standard radiographic techniques have limitations in detecting intraocular foreign bodies.
• Accurate localization of intraocular foreign bodies is crucial for effective treatment and preventing vision loss.

Observation:

• A patient presented with heterochromia iridis and clinical suspicion of ocular siderosis.
• Conventional examination methods, including standard radiography, failed to identify any foreign material within the eye.

Findings:

• Computerized axial tomography (CAT) successfully confirmed the presence of a metallic foreign body.
• The imaging provided precise localization of the intraocular foreign body, which was not apparent on standard X-rays.

Implications:

• Computerized axial tomography offers superior sensitivity for diagnosing intraocular foreign bodies compared to conventional radiography.
• This case highlights the importance of advanced imaging in managing suspected intraocular foreign bodies, especially when initial assessments are inconclusive.
• Early and accurate diagnosis using CAT can lead to timely intervention and potentially better visual outcomes in cases of ocular siderosis.
