title: Analysis of alternative methods for determining ocular irritation.
abstract: According to classification and labelling requirements, chemicals, dyes, agrochemicals and pharmaceutical formulations have to be evaluated for their potential to induce eye irritancy or corrosion. An attempt was made to analyse the predictive power of the bovine eye-chicken egg chorioallantoic membrane (BE-CAM) assay in comparison with results obtained using the conventional Draize method. In summary, results showed limited correlation between reactions in vitro and responses of eyes in vivo. In a pilot study, ultrasonic pachymetry showed high sensitivity and fairly good correlation between corneal thickness and clinical observations in eyes.
