Massive fibrosis of extraocular muscles related to intraocular tumor
1Department of Ophthalmology, Rambam Medical Center, Haifa, Israel.
Abstract:
A resin histological and ultrastructural study of 9 fibrotic extraocular muscles from 2 patients who underwent enucleation because of advanced intraocular malignant melanoma is reported. Total fibrosis of the extraocular muscles was evident in one case and extensive fibrosis in the other case. The patients did not suffer from congenital fibrosis syndrome. Ultrastructurally, the muscle tissue was replaced by collagen fibrils showing great variability of caliber.
