    Aim: The functional state of central hemodynamics in visually impaired girls of 7 and 8 years old, depending on the age and degree of impairment of their visual analyzer, was studied and compared with the indices of healthy children of the control group. Materials and method: The functional state of the cardiovascular system (CVS) was assessed by the parameters of the stroke volume (SV) of the blood, determined by tetrapolar thoracic rheoplethysmography, heart rate, minute blood volume, systolic blood pressure (SBP), diastolic BP, and mean hemodynamic BP. The adaptation potential of the CVS was studied at the beginning and at the end of the school year as a manifestation of the functional and adaptive capabilities of the circulatory system and the organism as a whole. Results: It was found that changes in the parameters of the CVS from 7 to 8 years in visually impaired girls do not correspond to the generally accepted ideas about its age dynamics: There are an increase in the frequency of cardiac contractions and a decrease in the SV and minute volume of blood and SBP. In this case, girls aged 7 years with a severe visual impairment (total detachment of the retina, glaucoma, and microphthalmos) experience the greatest stress in the state of hemodynamics in comparison with other visually impaired children and control girls. Conclusion: Thus, the period of adaptation to school in children with an abnormal visual analyzer proceeds more strenuously, and the adaptation reactions of the CVS predominate over the age-related dynamics of its parameters.
