Abstract
Sodium is readily absorbed by the corneal stroma when there is no surface epithelium and the denuded area fluoresces under u.-v. light. This chemical can penetrate intact epithelium only after prolonged exposure but penetrates devitalized or developing epithelium more readily. The intensity of the fluoresence is a measure of the integrity of the epithelium.Keywords
