The results are given of a study of the qualitative and quantitative composition of bioflavonoids and phenolcarbonic acids in samples of medicinal plant raw material Bupleurum L., Aloe Asphodeloideae, grown in the collection nursery of the Central Botanical Garden of the National Academy of Sciences of Belarus. Using HPLC, spectrophotometry and paper chromatography, aglucones of flavonols were identified and a high content of bioflavonoids and phenol carboxylic acids was established. These samples were used to create medical products for contact lens care.

On the large factual material, the effectiveness of videocomputer auto-training with the Amblyocor device is shown. Numerical estimates are given of improvement in visual acuity in children with disbinocular and refractive forms of amblyopia.

The functional visual impairment of the optic nerve was confirmed by the method of visual evoked potentials. In 1-4 groups of patients with optic neuritis, the N75 and P100 latency increased. An increase in latency indicates a lesion of the myelin sheath, which is associated with a decrease in the rate of potentials in the optic nerve. The analysis of the amplitude of the VEP revealed a significant increase in this index in groups 1 and 2 and a decrease in groups 3 and 4 as compared to the control group. The decrease in the amplitude of the VEP is associated with blockade of impulses, due to axial axonal cylinder damage.
