Early diagnosis of primary open-angle glaucoma plays a key role in preventing irreversible vision loss and slowing the progression of the disease. Despite the widespread use of modern diagnostic methods in developed countries, a significant number of glaucoma cases remain undetected by physicians. The aim of this study was to improve the processes of early diagnosis of primary open-angle glaucoma by analyzing data from 24-hour intraocular pressure monitoring using the portable Icare tonometer. The study included 80 patients (140 eyes) with early stages of the disease. The participants were divided into two groups: the first group included patients with stage I primary open-angle glaucoma, and the second group included patients with stage II of the disease. All eyes underwent 24-hour tonometry using the Maklakov tonometer and the portable Icare device. In addition, pachymetry was performed to determine the influence of central corneal thickness on intraocular pressure values. Analysis of the obtained data showed that the results of intraocular pressure measurements obtained using the Icare tonometer corresponded to the data obtained with Maklakov tonometry. Minor differences were observed only in some cases, reaching up to 2 mmHg higher and up to 1 mmHg lower according to the Icare measurements. The results of the study indicate that ophthalmotonus measurements using the Icare tonometer in patients with early-stage glaucoma show statistically comparable results to those obtained using the Maklakov method, making this device an effective tool for daily monitoring and diagnosis of glaucoma.
