Change of the crystalline lens in workers in hot shops
Oftalmol Zh 22(2): 128-130
Cataracts resulting from burns were found in workers in hot shops. The structure of these cataracts differ somewhat from typical cataracts, described by Vogt and others. Of the 641 workers examined who were systematically affected by infra-red rays, 40 had senile cataracts; 8 had cataracts on the anterior pole of the crystalline lens; and 16 had cataracts on the posterior pole of the crystalline lens. More frequently the change of the crystalline lens was found in those who had worked for 10 to 20 years. Of the 190 workers examined who were less frequently X-rayed with infra-red rays, 8 men were found to have senile cataracts, 2 had cataracts on the anterior pole of the crystalline lens, and 2 had cataracts on the posterior pole of the crystalline lens. As with the first group of those X-rayed, the change of the crystalline lens was more frequently found in those 40 years of age, and in those who had worked for 10 to 20 years. The protective goggles worn in the hot shops of the plants studied did not provide full protection from the effect of infra-red rays. The use of light filters with blue grass or eye glasses made of reflecting glass are recommended for the prophylaxis of cataracts caused by the rays.
