Оценить применимость паттерн-электроретинографии (ПЭРГ) для дифференциальной диагностики офтальмогипертензии и впервые выявленной первичной открытоугольной глаукомы (ПОУГ) начальной стадии.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. Проспективное нерандомизированное когортное исследование. Включали пациентов старше 35 лет с впервые выявленной офтальмогипертензией и ПОУГ начальной стадии хотя бы на одном глазу. Всем пациентам проводили стандартное офтальмологическое обследование и выполняли комплекс дополнительных методов, применяемых для диагностики ПОУГ: пахиметрию, исследование биомеханических свойств роговицы (Ocular Response Analyser, Reichert), пороговую статическую периметрию (Octopus 900, Haag-Streit Diagnostics), оптическую когерентную томографию (ОКТ) диска зрительного нерва (ДЗН) и макулярной области (OCT Triton Plus 3000, Topcon) и ПЭРГ (Diopsys Nova, Diopsys Inc.). Анализировали данные обоих глаз всех включенных пациентов (12 глаз в группе офтальмогипертензии и 26 глаз в группе ПОУГ). Статистическую обработку материала проводили с помощью пакета программ StatPlus:mac (StatPlus Inc., Тайвань).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Мы получили статистически значимые отличия показателей ПЭРГ устойчивого состояния по протоколу PERG-24 (магнитуды, магнитуды D — учитывающей значение магнитуды и изменчивости фазы ответа на протяжении всего теста — и их обратного отношения, определенных при контрастностях паттерна 100% и 85%) между исследуемыми группами при сопоставимом уровне внутриглазного давления, толщины роговицы, показателей ее биомеханических свойств и сопоставимых величинах периметрических индексов, средней толщины слоя нервных волокон сетчатки и комплекса ганглиозных клеток сетчатки (ГКС) по данным ОКТ. При этом все показатели ПЭРГ в группе пациентов с офтальмогипертензией находились в пределах нормы, а отдельные показатели ПЭРГ в группе пациентов с ПОУГ имели отклонения от нормы.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. ПЭРГ устойчивого состояния может являться дополнительной объективной методикой раннего выявления нарушений в функционировании ГКС, позволяющей провести дифференциальную диагностику офтальмогипертензии без повреждения ГКС и ПОУГ в начальной стадии. Кроме того, динамическое проведение ПЭРГ устойчивого состояния у лиц с офтальмогипертензией может позволить в более ранние сроки выявить начавшуюся гибель ГКС, т.е. развитие ПОУГ, чем компьютерная периметрия и ОКТ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>PURPOSE</title><p>PURPOSE. To evaluate the clinical utility of pattern electroretinography (PERG) in the differential diagnosis of ocular hypertension and newly diagnosed primary open-angle glaucoma (POAG) of the initial stage.</p></sec><sec><title>METHODS</title><p>METHODS. This prospective non-randomized cohort study included patients over the age of 35 years with newly diagnosed ocular hypertension and initial stage POAG in at least one eye. All patients underwent a standard ophthalmological examination, as well as a complex of additional methods used to diagnose POAG: pachymetry, examination of the biomechanical properties of the cornea (Ocular Response Analyzer, Reichert), standard automated perimetry (SAP) (Octopus 900, Haag-Streit Diagnostics), optical coherence tomography (OCT) of the optic nerve head (ONH) and macular area (OCT Triton Plus 3000, Topcon) and PERG (Diopsys Nova, Diopsys, Inc.). Data from both eyes of all included patients were analyzed (12 eyes in the ocular hypertension group and 26 eyes in the POAG group). Statistics was calculated using the StatPlus:mac Software package (StatPlus Inc., Taiwan).</p></sec><sec><title>RESULTS</title><p>RESULTS. During this study we recorded statistically significant differences in steady-state PERG parameters according to the PERG-24 protocol (magnitude, magnitude D — taking into account the magnitude and variability of the response phase throughout the test — and their reverse ratio, determined at pattern contrasts of 100% and 85%) between the groups of patients with newly diagnosed ocular hypertension and newly diagnosed initial stage POAG with a comparable level of intraocular pressure, corneal thickness, biomechanical properties and comparable perimetric indices, as well as the average thickness of the retinal nerve fiber layer and the ganglion cell complex according to OCT data. At the same time, all PERG parameters in the ocular hypertension group were within the normal range, while individual PERG parameters in the POAG group had deviations from the normal.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. Steady-state PERG may be an additional objective method for early detection of disorders in the functioning of retinal ganglion cells (RGCs), which allows differential diagnosis of ocular hypertension without damage of RGCs and initial stage POAG. In addition, dynamic examination with steady-state PERG of individuals with ocular hypertension may allow early detection of the onset of retinal ganglion cells death, i.e. the development of POAG, than with SAP and OCT.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>паттерн-электроретинограмма</kwd><kwd>ПЭРГ</kwd><kwd>первичная открытоугольная глаукома</kwd><kwd>офтальмогипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pattern-electroretinogram</kwd><kwd>PERG</kwd><kwd>primary open-angle glaucoma</kwd><kwd>ocular hypertension</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vrabec J.P., Levin L.A.
