摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to ophthalmology. Chromatic macular (local) ERG to red stimulus is carried out. Absence of biopotential is registered. Chromatic macular (local) ERG is carried out, amplitude and latency to green stimulus are estimated. Registered are reduction of a-wave amplitude on M-ERG to green stimulus to 28-48%, elongation of a-wave latency to 102-121%, reduction of b-wave amplitude to 66-94%, elongation of b-wave latency to 117-128%. Chromatic macular (local) ERG to blue stimulus is carried out. Registered are reduction of a-wave amplitude to 75-92%, elongation of latency of a-wave to 94-115%, reduction of b-wave amplitude to 80-100%, elongation of b-wave latency to 107-123%. Multifocal ERG ia carried out. Registered are reduction of retinal density P1 to 26-85.5%, reduction of amplitude N1 component to 7-79% and reduction of P1 component to 43-85%, elongation of N1 latency to 132-204% and P1 to 156-186%, mostly in central than in paracentral parts. Mixed ERG is carried out. Registered are reduction of a-wave amplitude to 34-80%, elongation of a-wave latency to 98-117%, b-wave amplitude to 84-105%. High-frequency rhythmic ERG is carried out. Absence or sharply subnormal rhythmic ERG is registered. ERG to long-lasting stimulus is carried out. If there is no OFF-response of ERG to long-lasting stimulus, achromatopsia is diagnosed.EFFECT: method makes it possible to diagnose achromatopsia by means of electroretinographic methods of examination on the basis of objective electroretinographic criteria and pathognomonic symptomocomplex.5 dwg, 1 exИзобретение относится к медицине, а именно к офтальмологии. Проводят хроматическую макулярную (локальную) ЭРГ на красный стимул. Регистрируют отсутствие биопотенциала. Проводят хроматическую макулярную (локальную) ЭРГ, оценивают амплитуду и латентность на зеленый стимул. Регистрируют снижение амплитуды а-волны на М-ЭРГ на зеленый стимул до 28-48%, удлинение латентности а-волны
