[Application of the functional-topical diagnostic method to identify the pathological process in patients with age-related macular degeneration.]

Abstract

Along with increasing life expectancy and aging of the population, there is an increase in the incidence of age-related macular degeneration (AMD), which often leads to blindness or irreversible vision loss and has a pronounced impact on the quality of life. Application of an extended complex of diagnostic techniques in ophthalmologic practice in order to expand the possibilities of early diagnosis and prognosis of the disease is urgent. Screening examination of patients with AMD was carried out. The technology of registration of global rhythmic activity of the brain with narrow-band filtering and long summation time was applied with the allocation of mainly long-lasting rhythmic oscillations in the frequency spectrum of 0,1-30 Hz. The peculiarities of the state of autonomic receptors of the eye in AMD have been determined. The prognostically significant signs of changes in the spectrum of the brain activating system at early and late stages of AMD were identified. The information characteristic of the weight of the sign of AMD development was obtained; that allowed to distinguish the ophthalmologic status of patients with AMD. The use of functional-topical diagnostics based on spectral analysis of rhythmic brain activity can be used as an additional non-invasive diagnostic screening test for early development of AMD, which will ensure timely and competently prescribed treatment and allow to achieve better long-term clinical outcomes.
