ker·a·to·ma·la·cia (ker″ə-to-mə-laґshə) [kerato- + malacia] a corneal condition, usually bilateral, associated with vitamin A deficiency. It begins with xerotic spots (Bitot spots) on the conjunctiva, while the cornea becomes xerotic and insensitive (xerotic keratitis); as the condition progresses, the haze increases until finally the entire cornea becomes soft, and colliquative necrosis occurs.
