Rehabilitation methods for individuals with functional vision disorders

Abstract

Purpose - to develop a rehabilitation system for people with functional vision disorders. Material and methods. The study included 56 schoolchildren with functional visual impairments aged 8-17 years, among which 7 had spasm of accommodation, and 49 - paralysis or paresis of accommodation. The examination included visometry, refractometry, ophthalmometry, measurement of the axial eye length, absolute and relative accommodation parameters, fusional reserves, as well as character of binocular vision and asthenopic complaints. Results. The patients with spasms, pareses and paralyses of accommodation were revealed to have decreased visual acuity, absence or sharp decrease in absolute and relative accommodation, fusional reserves, and simultaneous vision. A method for treating such patients has been developed, which aims for improvement of the blood supply to the ciliary muscle, accommodation reflex, visual acuity and differential sensitivity of the retina, vergence and version accommodation tonicity, convergence and fusion ability. The treatment led to normalization of absolute and relative accommodation, and increase of fusional reserves. The character of vision became binocular, asthenopic complaints stopped. The «anlauf» glasses allow longterm preservation of the effect of received treatment, as well as prevention of visual disturbances in eye-straining work. Conclusion. The complex approach to the treatment of patients with spasms, pareses and paralyses of accommodation leads to restoration of the functions of visual analyzer in fairly short time (15-20 sessions).
