It has long been known that the virus of trachoma can affect the cornea and limbus as well as the conjunctiva. During the active phase the superior limbus exhibits follicles composed of aggregations of lymphocytes surrounding a germinal center of reticuloendothelial cells. Regression of the follicles leads to depressed, round thinned areas known clinically as Herbert's pits. The present case exhibits the histopathology of Herbert's pits. The clinical diagnosis was confirmed by Dr. Phillips Thygeson. The eyes were subsequently obtained at autopsy.
