ABSTRACT
Table 74 Scale of Weighted Scores for Grading the Severity of Ocular Lesions (developed by Draize et al)
In 1994, Draize et al.1 described an eye irritancy grading system for evaluating drugs and other materials intended for use in or around the eye. Numerical scores were assigned for reactions of cornea, iris, and conjunctiva. The total ocular irritation score was calculated by a formula that gave the greatest weight to corneal changes (total maximum = 80). A total maximum score = 10 for the iris, and 20 for the conjunctiva.
