Среди них основное внимание привлекают атрофические изменения слоя нервных волокон сетчатки (СНВС). При этом диагностическая значимость метода ОКТ при БП до сих пор остается спорной. </p><sec><title>Цель исследования</title><p>Цель исследования: исследовать толщину СНВС при БП с последующим определением значимости метода ОКТ для диагностики заболевания. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. У пациентов с БП (n = 24) и в контрольной группе (n = 20) с помощью ОКТ была исследована толщина СНВС — средняя, в квадрантах и в 10 секторах. </p></sec><sec><title>Результаты</title><p>Результаты. У пациентов с БП выявлено истончение СНВС в нижнем квадранте по сравнению с контрольной группой (р = 0,009). Чувствительность и специфичность метода составили соответственно 56% и 82%. Толщина СНВС не была связана со сторонностью паркинсонической симптоматики, длительностью или тяжестью заболевания. В контрольной группе и у пациентов с БП отмечена связь толщины СНВС с возрастом. </p></sec><sec><title>Заключение</title><p>Заключение. БП характеризуется атрофическими изменениями сетчатки в виде истончения СНВС в нижнем квадранте, что подтверждает системность нейродегенеративной патологии при данном заболевании, выходящей за пределы черной субстанции и вещества головного мозга. При этом толщина СНВС показала ограниченную диагностическую значимость для выявления случаев данного заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><p>In Parkinson’s disease (PD), some structural changes in the retina have been shown using optical coherence tomography (OCT).

In patients with PD thinning of RNFL in the inferior quadrant was revealed (p = 0.009). The sensitivity and specifi city of the method were 56% and 82%, respectively. The thickness of RNFL was not associated with parkinsonian symptoms asymmetry, duration and severity of the disease. In the control group and in PD patients, there was a relationship between the RNFL thickness and age. </p></sec><sec><title>Conclusion</title><p>Conclusion. PD is characterized by atrophic changes in the retina in the form of thinning of RNFL in the inferior quadrant, which confi rms the systemic nature of neurodegenerative pathology in this disease going beyond the substantia nigra and brain tissue. At the same time, the thickness of RNFL showed limited diagnostic value for detecting PD cases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>оптическая когерентная томография</kwd><kwd>слой нервных волокон сетчатки</kwd><kwd>нейродегенерация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson disease</kwd><kwd>optical coherent tomography</kwd><kwd>retinal nerve fi ber layer</kwd><kwd>neurodegeneration</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РНФ № 19-15-00320</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nguyen-Legros J.
