Spindleform scleropathy: collagen changes of the sclera. A pathologic report.

To our knowledge, this is the first pathologic report of interscleral collagen bundle changes occurring as well-defined spindleform lesions randomly interspersed within the sclera. The lesions were observed in an otherwise healthy 75-year-old man whose eye was enucleated because of a uveal malignant melanoma. There are few reports in the literature of focal scleral changes of a predominantly acid mucopolysaccharide nature. The entity we observed in this case differs from these reports by its spindleform appearance, random distribution (not overlying the melanoma) and predominantly vicinal glycol nature. Histopathologic, histochemical, and ultrastructural studies revealed that the lesions were not the result of mucoid degeneration of the scleral collagen and not an abnormal collagen structure.
