Ultraviolet radiation‐B‐induced cataract in albino rats: maximum tolerable dose and ascorbate consumption

Abstract

The MTD for avoidance of UVB-induced cataract in the 7-week-old albino Sprague Dawley rat was estimated to be 3.01 kJ/m(2). In vivo UVB exposure of the rat eye decreases lens ascorbate content following an exponential decline, and suprathreshold doses cause greater effect than subthreshold doses.
