[Depth visual function and the relative accommodation reserves of patients before and after keratotomy]. / Sostoianie glubinnogo zreniia i rezervov otnositel'noi akkomodatsii u bol'nykh do i posle keratotomii.

Reserves of relative accommodation and thresholds of remote vision have been investigated in 60 patients with myopia of different degree before radial keratotomy and 1.5-2.0 years after the surgery. It was firstly established that the state of accommodation and remote vision for near before surgery influences the stability of the obtained postoperative effect. This fact should be considered when planning keratotomy. A conclusion is made that for patients with reserves of accommodation of the positive part not lower that 2.0D and the threshold of remote vision for near not higher than 7 mm keratotomy is not advisable.

[Detection of latent disorders of visual function during ambulatory care of children]. / Vyiavlenie latentnykh rasstroistv zritel'nykh funktsii v protsesse dispanserizatsii detei.

For the purpose to select tests for diagnosis of latent disturbances of visual functions, dynamic observation was conducted over 88 healthy school children within 5 years (from the 3d to the 8th form). Once a year, the children underwent examination of visual acuity for far and near, the state of binocular vision on a synoptophore and a color test, the volume of relative and absolute accommodation, muscular balance of eyes for far and near, contrast sensibility, the time of perception of the negative successive contrast, refraction. For the period of 5 years, 7 children developed myopia of low degree, 32 showed transitory or lasting reduction of visual acuity due to spasm of accommodation. The authors believe that the most rapid and informative tests for diagnosis of latent disturbances in accommodation-convergence system are visual acuity for near, the volume of absolute accommodation, the threshold of remote vision, muscular balance of eyes for near. It is recommended to use these tests widely when conducting ophthalmologic thorough prophylactic examinations of children.
