В исследование были включены 194 глаза с кератоконусом (113 пациентов в возрасте от 23 до 36 лет). Рефракция роговицы в центральной зоне у пациентов колебалась от 48,25 до 56,75 дптр, толщина роговицы составляла от 279 до 558 мкм. Распределение пациентов по степени развития кератоконуса проводили согласно классификации Amsler: I стадия - 40 глаз; II стадия - 78 глаз; III стадия -54 глаза; IV стадия - 22 глаза. Всем пациентам проводили стандартное офтальмологическое обследование, включая пневмотонометрию. Внутриглазное давление (ВГД) и биомеханические свойства роговицы измеряли с помощью динамической двунаправленной аппланации и пневмоимпрессии роговицы.</p></sec><sec><title>Результаты</title><p>Результаты. Прижизненное исследование биомеханических свойств роговицы у пациентов с кератокону-сом выявило снижение показателей корнеального гистерезиса (КГ) в среднем до 8,42±1,12 мм рт. ст., фактора резистентности роговицы (ФРР) - до 7,45±0,96 мм рт. ст. и коэффициента упругости (Ку) - до 5,35±0,87 мм рт. ст. При этом их величина значительно варьировала в зависимости от стадии кератоконуса. Среднее значение показателя роговично-компенсированного ВГД (ВГДрк) во всей выборке составило 15,08±2,43 мм рт. ст., ВГД, приравненного к Гольдману (ВГДг) - 11,61±2,37 мм рт. ст., пневмотонометрического ВГД (ВГДп) - 10,13±2,94 мм рт. ст. Независимо от стадии заболевания показатели ВГДрк между собой не имели статистически значимых отличий, тогда как по мере прогрессирования заболевания показатели ВГДг и ВГДп демонстрировали неуклонное статистически значимое снижение средних значений.</p></sec><sec><title>Выводы</title><p>Выводы. По мере прогрессирования кератоконуса биомеханические свойства роговицы изменяются в сторону ослабления, что обусловливает снижение значений таких показателей, как ВГД, приравненное к Гольдману, и ВГД пневмотонометрическое, в отличие от роговично-компенсированного ВГД.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: Evaluation of corneal biomechanical properties and their influence on IOP indices in patients with keratoconus.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 194 eyes with keratoconus (113 patients aged from 23 to 36 years). Corneal refraction in central zone varied from 48.25 to 56.75 D, values of corneal thickness ranged from 279 to 558 pm. Patients were divided into 4 groups according to Amsler classification: I stage - 40 eyes; II stage - 78 eyes; III stage - 54 eyes and IV stage - 22 eyes. Standard ophthal-mological examination was carried out including pneumotonometry. IOP indices and values of biomechanical properties were evaluated by dynamic bidirectional pneumatic applanation and pneumatic impression.</p></sec><sec><title>Results</title><p>Results. Study of corneal biomechanical properties in patients with keratoconus showed a decrease of such biomechanical indices as corneal hysteresis (CH) on average to 8.42±1.12 mm Hg, corneal resistance factor (CRF) -to 7.45±0.96 mm Hg, coefficient of elasticity (CE) - 5.35± 0.87 mm Hg. Values of these indices strongly depended on the stage of keratoconus. In the whole sample, the average corneal compensated IOP (IOPcc) amounted to 15.08± 2.43 mm Hg, Goldman IOP (IOPg) was 11.61±2.37 mm Hg and pneumatic tonometry IOP (IOPp) was 10.13±2.94 mm Hg. IOPcc indices didn't have any statistically significant difference in dependence on the stage of keratoconus (р&gt;0.473), while in process of disease progression IOPg and IOPp indices showed statistically significant decrease of mean values.</p></sec><sec><title>Conclusion</title><p>Conclusion. Progression of keratoconus led to a decrease in corneal biomechanical properties which determine reduction of such indices as IOPg and IOPp in contrast to IOPcc.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кератоконус</kwd><kwd>ВГД</kwd><kwd>биомеханические свойства роговицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratoconus</kwd><kwd>IOP indices</kwd><kwd>corneal biomechanical properties</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">Rabinowitz Y.S.
