| description | Objective: to analyze the tonometric data, obtained with standard contactless tonometry and corneal-compensated tonometry, examined by the Oculus CorVis ST device in different groups of patients of the Tri-Z Krasnodar Clinic.Patients and Methods. The study included 42 eyes of patients, with glaucoma — 55 %, with suspected glaucoma — 45 %, mean age — 63.19 ± 1.7 years, men were 20 (47.5 %), women — 22 (52.5 %), the central corneal thickness was 554.43 ± 5.28 microns. Corneal tomography and biomechanical parameters were measured using Pentacam (Oculus) and Corvus ST, respectively.Results. IOP in people aged over 60 years was lower according to CorVis ST (Po 22.07 = 2.25, Pcс 18.63 ± 1.30, p = 0.007). IOP differed only in patients with a CCT of more than 580 µm (Po 22.4 ± 2.9, Pcc 18.21 ± 2.16, p = 0.012). IOP in patients with glaucoma was Ро 26.19 ± 3.5 and Рсс 21.3 ± 2.0, p = 0.008, without glaucoma — Ро 17.83 ± 9.60; Pсс 16.1 ± 5.5; p = 0.063. IOP in patients with compensated glaucoma Ро 17.34 ± 1.10, Pсс 16.6 ± 1.1, p = 0.354, with decompensated Ро 42.78 ± 6.8, Pсс 30.08 ± 4.10, p = 0.005. In the initial stage of glaucoma, Рo 22.5 ± 2.3, Рсс 20.0 ± 1.0, p = 0.297, in the advanced stage — Рo 20.7 ± 2.7, Рсс 17.6 ± 1.9, p = 0.027.Conclusion. Standard non-contact tonometry can be used in persons aged under 60 years, persons without glaucoma and with initial compensated glaucoma. In all other cases, the Oculus CorVis ST values are more accurate. |
