Abstract
The authors experienced corneal blood staining after traumatic hyphema with primary open angle glaucoma and studied corneal blood staining by electron microscope. The electron microscpic finding were as follows: 1. The destructive RBC particles were found in entire cornea except deep stroma by light microscope. 2. The destruction of endothelium and intact Descemet's membrane were found and few RBC particles in the keratocyte and interlamellar space were observed by electron microscope. 3. Amorphous granules in the superficial stroma were darker than the ones in the deep stroma by electron microscope. 4. The granules were observed between basal cell layer and wing cell layer in epithelium. We suggest that clearing mechanism of corneal blood staining are scavening action of phagocytic cells and migration from deep layer to superficial layer of granules.
