[Dynamics of visual functions in the conditions of glow and sodium lighting. I. Visual acuity, accommodation, flicker fusion, visual field and heterophoria].

Investigations of the functions cited in the title were performed in 23 persons with a normal visual system in conditions of equal illumination, first the glow and the next day or later--the sodium one. All the tests were carried out three times in the morning hours evaluating in this way their dynamics as the time goes. The authors are analyzing the degree of the variability of the discussed functions in the time, as well as their behaviour in conditions of applied illumination.

[Prevention of retinal detachment. I. Cryopexy before cataract extraction. Preliminary report].

The authors discuss the results of cryopexy applied prophylactically in 32 eyes. The freezing was executed at least 6 weeks before the cataract extraction in eyes endangered by retinal detachment. This were the high myopia eyes, so called fellow eyes and eyes in persons aged between 30 and 40 years.

[Organic changes of the visual system rendering difficult the attainment of binocular vision in children].

The authoress analyses 36 cases of children with organic changes of the visual system who revealed secondary squint. She tries to give evidence that the presence of structural changes makes difficult the treatment of squint and very often the organic changes are superimposed by functional changes.
