Ophthalmol J 2024;9:127-132.

Abstract

Conjunctival ultraviolet autofluorescence is a relatively new diagnostic method that is utilized to diagnose and quantify the amount of ocular ultraviolet exposure. It has also been used to monitor the progression of myopia. This article describes the principles of this method and the technical aspects. We give some examples of diagnosis and describe the various factors that influence it.
