[Possibilities of the use of low-energy laser effects on the ciliary body in optic nystagmus]. / Vozmozhnosti primeneniia nizkoénergeticheskogo lazernogo vozdeistviia na tsiliarnoe telo pri opticheskom nistagme.

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.

[Use of low-energy laser irradiation in patients with progressive myopia]. / Primenenie nizkoénergeticheskogo lazernogo izlucheniia u patsientov s progressiruiushchei blizorukost'iu.

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. By the end of the first follow-up year the mean values of the positive part of accommodation increased by 2.0 to 2.5 diopters in patients of all age groups. A reduction of the parameters of ocular function was recorded 6-12 months after laser stimulation, though they remained higher than initially. A repeated curse of therapy helped normalize accommodation reserve parameters again. Prestimulation rheographic coefficient in all the examinees was 2.7 +/- 0.03% on an average, after treatment it was 3.44 +/- 0.02%. Hence, ciliary muscle stimulation by infrared laser helps in the majority of cases stabilize clinical refraction.

[Late results of pathogenetically-oriented surgical treatment in congenital glaucoma and problems of medical rehabilitation]. / Otdalennye rezul'taty patogeneticheski orientirovannogo khirurgicheskogo lecheniia vrozhdennoi glaukomy, voprosy meditsinskoi reabilitatsii.

Results of pathogenetical surgical treatment of congenital glaucoma were analyzed in late periods after surgery, from 1 to 17 years, in 105 patients (171 eyes). Ophthalmic tone normalization was attained in 87.5% of cases. High vision acuity was retained in 57.7% of cases. The principal causes of reduced central vision in process stabilization were astigmatism in 61.7%, amblyopia in 71.5%, strabismus in 59%, anisometropia in 22.8%. To improve vision acuity computer-aided pleoptic treatment was carried out in the postoperative period in 42 children (76 eyes). The efficacy of the method was 84.2%.
