Calcification and ossification within the orbit

JL Sudheim and MS Lapayowker

The radiological diagnosis of orbital lesions can be aided by an understanding of the significance of the various kinds of calcium deposits. Orbital calcification may be metastatic or dystrophic, with ossification occurring in degenerated eye tissue in the presence of an abundant blood supply. It is the dystrophic type which is usually visualized radiographically. Intraorbital calcification had been categorized according to its configuration and location (a) ocular; (b) extraocular; and (c) extraorbital extending into the orbit on frontal radiographs. Lesions discussed include cataract, phthisis bulbi, vascular abnormalities, infection, and tumor.
