Threshold dose estimation for ultraviolet radiation induced cataract

Safety Limit Estimation for Cataract induced by Ultraviolet Radiation

Ultraviolet radiation-induced cataract: age and maximum acceptable dose.

PURPOSE To investigate the effect of age on ultraviolet radiation-B (UVR-B)-induced cataract and to detect the maximum acceptable dose in rats of different age groups. METHODS Four age groups of 20 rats each, aged 3, 6, 10, and 18 weeks, were included. Each age group was divided into five UVR-B dose subgroups. The rats were unilaterally exposed to UVR-B (lambda(max) = 302.6 nm, lambda(0.5) = ...

Cataract from Ultraviolet Radiation

Development and repair of cataract induced by ultraviolet radiation.

BACKGROUND Several epidemiological investigations show a correlation between cataract development and the dose of ultraviolet radiation (UVR) received. It is experimentally well established that exposure of animal eyes to UVR induces cataract. Most cataracts develop as a gradual increase in lens opacity. Despite this, current estimations of toxicity for cataract are based on the concept that ca...
