ABSTRACT
Physical and clinical eye refraction was studied in 608 children aged from 3 to 12 years. The formation of refraction of the eye at the time of its growth is based on correlative connexions between anatomo-optic parameters and between refractive media themselves. Spherical and astigmatic refraction are determined by refractive media having, in their most part, astigmatism. In the period of the growth of the eye, its physical and clinical refraction changes. To prevent a fall of visual functions and disturbances in the musculo-accommodative system of the eye, early optic correction of ametropia is recommended and, if indicated, pleoptic-orthoptic treatment.

The paper analyses immediate and remote results after medicamentous-surgical treatment of open-angle glaucoma of stages II and III with preliminary vasosection of facial vessels of the ophthalmic artery basin in 110 patients, aged under 60 years (21), from 61 to 70 (43), above 70 (46). Atherosclerosis of retinal vessels was recorded in 83.6% of patients, hypertonic disease--in 61.8%. The results of a 5-year period of observation have shown that in glaucoma of stage II visual functions remained at the initial level in 84% of patients, and of stage III--in 78.2%. Positive results of vasosection used as a means for improvement of hemodynamics in the internal coats of the eye and the optic nerve after antiglaucomatous operations confirm that, besides antiglaucomatous operations, it is necessary to use a complex of preparations and vasosection, thus improving the hemodynamics of the eye and providing preservation of visual functions.

A study of the character, causes and incidence of professional diseases of the eye in 3,588 workers of four industrial plants has shown that the most frequent causes of the disease are the action of dust, thermal reaction, chemically active products of production, the usage of obsolete equipment, low technology, insufficient measures of individual and collective protection of the eye. In workers with a length of service to 5 years the incidence of diseases made up 2.4%, and more than 10 years--10.8%, at the average. Economic losses due to one sick person achieved 3,017.3 doubles, at the average. Recommendations for improvement of prophylaxis of professional diseases of the eye are given.
