Методы тонометрии и роль различных проб в ранней диагностике глаукомы (часть 2)

This literature review depicts various tonometry methods (Maklakov, elastotonometry, Goldmann tonometry, tonometry by means of Ocular Response Analyzer (ORA) and ICare). The efficacy and accuracy characteristics of different intraocular pressure measuring methods are presented. The article sums up current research on the interdependence of the intraocular pressure and central cornea thickness, the influence of visco-elastic characteristics of the fibrous membrane of the eye on results of some tonometry methods, the correlation of biomechanical indices and interrelation of corneal hysteresis, corneal resistance factor and intraocular pressure. The review describes various tests used in early diagnostics of glaucoma: stress tests (mydriatic test, Wurgaft compression tonometry test, Heims position test, Krasnov orthoclinostatic test, corticosteroid provocative testing by B. Becker, W. Mills etc.)

Характер клинических проявлений ожогов глаз у пациентов с различным фенотипом ацетилирования при нормализованном внутриглазном давлении

PURPOSE: To study the character of clinical manifestations of ocular burns in patients with normal IOP and different acetylation phenotypes (APh).METHODS: We examined 103 patients with ocular burns (141 eyes) during their primary visit to the Republican Clinical Eye Hospital of the Ministry of Health of Uzbekistan, on different time-points during therapy (on days 2, 5, 7, 12 after the beginning of treatment) and then during an active clinical examination 30 days and 4 months after discharge. 44 patients were examined 1-2 years after suffering a burn injury in order to identify the later post-burn complications and their interpretation according to the patient’s APh. 52 (69 eyes) patients out of 103 examined patients (141 affected eyes) had a slow acetylation phenotype (SA) and 51 patients (72 eyes) — a fast acetylation phenotype (FA).RESULTS: The results of these studies allow us to assert that patients with SA phenotype develop deeper ocular burns, with eye tissue damages less prone to treatment than in FA patients, where less pronounced changes lead to faster process normalization. APh determines the course of the manifestations, their severity and risk of complications in ocular burns patients. Fast acetylation phenotype may serve as a prognostic marker of faster pathological changes regression in ocular tissues, whereas the slow acetylation phenotype suggests the development of more severe disease forms, often requiring a prolonged and complex therapy.
