A case of hyperplasia of the ciliary epithelium is reported because of several unusual circumstances present. The tumor was unusually large. Its presence was noted before removal of the eye. Except for the presence of cataract, the eye was not diseased. At the time of enucleation of the eye the patient was under 30 years of age. Histologically and clinically this tumor has proved to be benign. REPORT OF CASE F. K., a married white woman aged 29 years, was first seen on April 2, 1935. The patient complained of gradual diminution of vision in the left eye over a period of at least one year. She associated the impairment of vision in the left eye with a blow on the skull over the right parietal region. The previous ocular history was negative. The patient's medical history and physical examination did not reveal anything pertaining to her ocular condition.
