From: Keratocyte loss in corneal infection through apoptosis: a histologic study of 59 cases
The corneal stroma in a case of fungal keratitis shows diffuse TUNEL positivity in the zone of inflammation (*) as well as discrete positive staining in the peripheral keratocytes away from zone of inflammation (arrow head) (TUNEL, ×250) [Left]. The higher magnification of the same shows TUNEL positive nuclei of the keratocyte (Arrow) in a clean background, free of inflammatory cells. (TUNEL staining, ×500) (TUNEL ×400) [Right]
