[Effects of decreased nystagmus amplitude in children periodically exposed to light].

The effect of steady-state nystagmus suppression has been found upon periodic light exposure of the eye. The paper describes the exposure facility and procedure based on the changes in the amplitude and frequency of light pulse until there is a response of a patient's nystagmus parameters that are continuously monitored by video-assisted computer system. After periodic light exposures, there was a persistent suppression of nystagmus and a steady-state increase in visual acuity by an average of 0.

[Use of low-energy laser irradiation in patients with progressive myopia].

A method of infrared laser exposure at a wavelength 1.3 microns for the treatment of progressive myopia has been developed, permitting a contactless trans-scleral irradiation of the ciliary muscle. Laser stimulation was carried out in 117 patients (234 eyes) aged 7 to 16.
