Differential-diagnostic approach in assessing the nature of the course of partial atrophy of the optic nerve

Abstract

Purpose. To determine the diagnostic criteria for the progressive nature of the course of non-glaucomatous etiology of ONA according to the data of electrophysiological and Doppler studies. Material and methods. In accordance with the purpose of the study, 3 groups were formed of 95 patients aged 37 to 72 years, (average age 56±9 years), 53 of them were men and 42 were women. Clinical data of three clinical groups were compared, of which the first group with stationary ONA, the second with progressive ONA, and the third control group, without pathology of the retina and optic nerve. Results. It was revealed that the progressive nature of the course of non-glaucomatous ONA is influenced by changes in indicators such as electrical lability of the optic nerve, maximum systolic and end diastolic blood flow velocity in the ophthalmic artery and in the lateral posterior short ciliary arteries. Conclusion. The results formed the basis for our development of a method for assessing the course of ONA. Key words: partial atrophy of the optic nerve, electrophysiological studies, Doppler studies.
