[Possibilities of the use of low-energy laser effects on the ciliary body in optic nystagmus].

The accommodation potential of the eye is markedly reduced in patients with optic nystagmus. Trans-scleral exposure of the ciliary body to infrared low-energy laser at wavelength 1.3 microns may be used to repair the accommodation potential of the eyes and improve the visual function in nystagmus. Laser stimulation of the ciliary zone was carried out in 62 patients with optic nystagmus. As a result, the accommodation potential was 1.417 times increased and the closest point of clear vision approached the eye by 1.309 diopters. Far vision acuity increased by 1.334 times, close one by 1.258 times. A stable positive result persisted for 3 to 6 months, after which laser stimulation may be repeated, or other means of repairing the accommodation system of the eye be resorted to, such as training after Avetisov-Mats or exercises with a home ergographer.
