Aim. To study the change of electrical impedance measurements in brain in patients with the «dry» form of age-related macular degeneration before and after combined treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation. Methods. Two groups of patients with the «dry» form of age-related macular degeneration were examined. 40 patients (80 eyes) from the main group were treated using combined treatment and 39 patients (78 eyes) in the group of control who were treated conventionally. Results. Before the treatment, decreased blood flow in the internal carotid artery was found in 77.2%, and in the vertebral arteries in 82.2% of patients. Peak amplitude and the stress ratio index at rheoencephalography in the anterior cerebral circulation were 0.83±0.04 Ω and 27.46±0.40%, in the posterior cerebral circulation - 0.70±0.04 Ω and 23.78±0.35%. Peak amplitude values and the stress ratio index have improved significantly right after treatment and after 6 months in the main group compared to the control group. Mean visual acuity in the main group before treatment was 0.87±0.02, right after the treatment - 0.96±0.01 (p 0.001), 2 months after the treatment - 0.95±0.01 (p 0.001), 6 months after the treatment - 0.96±0.01 (p 0.001), 12 months after the treatment - 0.95±0.01 (p 0.001). In the control group mean visual acuity was 0.91±0.02 before the treatment, 0.95±0.02 (p 0.05) - right after the treatment. 2 months after the treatment - 0.94±0.02 (p 0.05), 6 months after the treatment - 0.92±0.02 (p 0.05). 12 months after the treatment mean visual acuity decreased and equaled 0.89±0.02. Decrease of anterior cerebral circulation was found in 77.2% of patients with the «dry» form of age-related macular degeneration, mean peak amplitude value was 0.83±0.04 Ω and the stress ratio index was 27.46±0.40%, decrease of posterior cerebral circulation was found in 82.2% of patients, mean peak amplitude value and the stress ratio index were 0.70±0.04 Ω and 23.78±0.35%. Conclusion. In patients with the «dry» form of age-related macular degeneration posterior cerebral circulation has improved significantly and visual acuity has improved 6 months after combined treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation.

Aim. To study the electrophysiological parameters in patients with the «dry» form of age-related macular degeneration before and after combined treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation. Methods. Two groups of patients with the «dry» form of age-related macular degeneration were examined. Patients in the main group (40 patients, 80 eyes) were treated with a combination of polarized polychromatic non-coherent light and dynamic electromyostimulation, patients in the control group (39 patients, 78 eyes) were treated conventionally. Mean age of the patients was 71.3±1.1 years. All patients underwent standard ophthalmic examination. To assess the functional status of the macula, electroretinography was performed using the «Neuro-MVP» device (Ivanovo, Russia). A-wave amplitude and latency on the red light stimulus were examined. Results. A-wave amplitude on macular electroretinogram was 11.9% lower and A-wave latency was 20.8% higher in patients with age-related macular degeneration compared to healthy subjects. A statistically significant improvement of the A-wave amplitude and latency was observed on macular electroretinogram after the combined treatment. A-wave amplitude increased from 13.22±1.36 to 17.17±1.59 µV (p 0.01) after 2 months and up to 17.80±1.60 µV (p 0.05) after 6 months of treatment. A-wave latency decreased from 19.32±0.41 to 18.51±0.36 ms (p 0.01) after 2 months and down to 18.31±0.45 ms (p 0.05) after 6 months of treatment. There was a relevant increase in A-wave amplitude from 13.15±1.09 to 16.3±1.09 µV (p 0.01) and decrease in A-wave latency from 19.23±0.30 to 18.64±0.30 ms (p 0.05) in patients of the control group 2 months after the end of treatment. Conclusion. There were relevant increase in A-wave amplitude and decrease in A-wave latency observed on macular electroretinography after treatment. The proposed treatment method does not cause any complications and can be used as a treatment option in patients with allergic reactions to standard drugs.

Aim. To assess the antioxidant capacity in patients with the «dry» form of age-related macular degeneration before and after combined treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation. Methods. Two groups of patients with the «dry» form of age-related macular degeneration were examined. 40 patients (80 eyes) from the main group were treated using combined treatment and 39 patients (78 eyes) in the group of control who were treated conventionally. The integral blood antioxidant capacity was measured by galvanometry. Results. Blood antioxidant capacity in healthy subjects is 26.0 kC/l. In patients of the main group blood antioxidant capacity before the treatment was equal to 22.81±0.27 kC/l, compared to 22.17±0.20 kC/l in control group (total mean value 22.49±0.27 kC/l). There was a relevant elevation of the blood antioxidant capacity at the late stages after the treatment - up to 12 months, compared to only 2 months in the control group. Visual acuity in patients of the main group before the treatment was 0.87±0.02, after the treatment was finished - 0.96±0,01 (p 0.001), 2 months after the treatment - 0.95±0.01 (p 0.001), 6 months after the treatment - 0.96±0.01 (p 0.001), 12 months after the treatment - 0.95±0.01 (p 0.001). Visual acuity in patients of the control group before the treatment was 0.91±0.02, after the treatment was finished - 0.95±0.02 (p 0.05), 2 months after the treatment - 0.94±0.02 (p 0.05), 6 months after the treatment - 0.92±0.02 (p 0.05). 12 months after the treatment the visual acuity deteriorated compared to the treatment start and was measured as 0.89±0.02. Conclusion. There is a decrease of blood antioxidant capacity (22.49±0.27 kC/l) in patients with the «dry» form of age-related macular degeneration; a relevant increase of blood antioxidant capacity and visual acuity can be observed up to 12 months after the treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation.
