INDIVIDUAL NORMAL RANGE OF INTRAOCULAR PRESSURE IN EARLY GLAUCOMA DIAGNOSTICS
Aim: to demonstrate the benefit of individual normal range of intraocular pressure (inIOP) in early glaucoma diagnostics. Material and methods. The study included 40 patients (40 eyes) without established glaucoma diagnosis, no hypotensive regimen and average IOP level corresponding with the typical norm of ≤ 21 mm Hg, but at the same time exceeding inIOP level of ≤ 13.4 ± 4.1 mm Hg. All patients underwent visometry, biomicroscopy, tonometry, inIOP calculation, standard automated perimetry, retinal tomography. Follow-up period was 12 months. Results and discussion. At the baseline examination we revealed glaucomatous changes of morphofunctional parameters. After IOP level reduction to correspond with the individual normal range, all parameters were stabilized and showed no progression during the follow-up period. Conclusion. The method of individual normal range of intraocular pressure calculation may prove to be beneficial for early glaucoma diagnostics, as well as treatment tactics assessment.
