Abnormal process which, in the eye, results in hornification of the epithelial layer of the conjunctiva or cornea. It may be hereditary or due to irritation (e.g. radiation) or to prolonged drug administration in the eye. It appears as a dry white plaque (called leucoplakia or leucokeratosis). It may be benign or malignant, in which case it must be surgically excised. See pterygium.
