摘要
FIELD: medicine. SUBSTANCE: method involves showing test objects and recording visual invoked potentials. A white-and black vertical strips test object reversible in time is shown first of all. Then averaged maximum amplitude of the main positive peak P100. is measured. Then, a test object, arranged as horizontal white and black strips reversible in time, is shown. Then averaged maximum amplitude of the main positive peak P100. is measured. Next to it, ratio of the maximum amplitude of the main positive peak P100 when showing vertical strip test, to maximum amplitude of the main positive peak P100 when showing horizontal strip test, is determined. The ratio value being found in interval from 0.1 to 0.6, meridional amblyopia aggravated by direct hypermetropic astigmatism is to be diagnosed in children. EFFECT: high accuracy of diagnosis. 4 dwg
