effect of exposure to heat on the human eye

This study aim to investigate the effect of heat on the exposed worker's eye and to estimate visual disturbances among the workers. 50 exposed worker and 40 control undergo a complete medical examination including measuring of blood pressure and glucose in urine, opthalmological examination for V.A., oblique illumination, occular tension; slit lamp and fundus examination. The indoor wet bulb globe temperature was calculated. Changes in the visual acuity well found, 4% chronic blepharitis, 10% corneal lesions, 16% posteiror cortical cataract and 14% myopicfundus. No iris changes or intraocular tension change well found. Most of these findings well attributed to heat exposure and different recommendations were given
