Trabecular and retrocorneal proliferation of melanocytes and secondary glaucoma.

A 59-year-old woman with no evidence of glaucoma developed secondary open-angle glaucoma after an intracapsular cataract extraction complicated by vitreous and iris incarceration. Histopathologic and scanning and electron microscopic studies of the enucleated eye 22 years later revealed extensive proliferation of iris melanocytes across the trabecular meshwork and posterior surface of the cornea. Proliferation of iris stromal melanocytes over the trabecular meshwork may have caused secondary open-angle glaucoma.
