OBJECTIVE: To study clinic significance of ocular and orbital diseases with computed tomographic (CT) scans.
METHODS: 2181 ocular and orbital photos of computed tomographic scans were reviewed. The relevance with pathogenesis, diagnosis criteria and differential diagnosis of calcification was analyzed.
RESULTS: Of 2181 CT scans, 129 showed calcified densities. 40 cases (31%) with retinoblastoma, and 3 cases (1%) with chorodal osteoma were revealed intraocular lesions containing calcium. The massive calcification was demonstrated in orbital diseases including 58 cases (45%) with vascular lesions, 19 (15%) cases with other orbital benign tumors and 9 cases (8%) with orbital malignant tumors.
CONCLUSION: The calcification number, location and shape within lesions are of great value in the diagnosis of ocular and orbital diseases.
