Effect of Infrared Radiation on Eyes with Progressive Myopia

Overview

In the submitted paper the authors pay attention to infrared radiation close tovisible light is intensly absorbed by haemoglobin, melanin and xantophyll where-by part of the radiation energy is transformed into heat. The authors present threeseries of experiments where they investigated by different methods changes inthe vitreous body after exposure to light, infrared radiation or raised temperature.Theys assume that on the defocused eye with a myopic conus which developed asa result of an inborn inadequate closure of the optic cup the light can cause a riseof temperature in the vitreous body. This leads to metabolic changes characterizedby increased activity of lyzosomal enzymes causing loss of the spatial structureof hyaluronic acid and collagen biomolecules. Penetration of the altered vitreousfluid trought the conus can lead to degradation of the interstitial substances ofthe sclera. Suitable absorption glasses filtering infrared light close to visible lightcould reduce the hyperthermia of the vitreous body.
