• A progressive nonedematous keratopathy developed in a 36-year-old patient after she was struck in the eye by glass fragments. Biopsy material that was examined by electron microscopy and electron beam microanalysis demonstrated the presence of intracorneal glass fragments, which could not be detected clinically. Retained intracorneal glass, generally thought to be completely inert, can be associated with a chronic keratopathy.
