Glaucoma Telemedicine Screening

Detailed Description: The aim of this study is to increase the detection of patients suspected of having glaucoma. For this purpose, the use of a combination of a mobile fundus camera and a mobile intraocular tonometer is proposed. These devices are used within the general practitioners' surgeries in the rural parts of Olomouc and Jeseniky region. Their combination will allow a better stratification of patients suspected of glaucoma into the following groups: * patients with ocular hypertension (higher intraocular pressure and normal optic disc) * patients with normotensive glaucoma (normal intraocular pressure and suspected optic disc) * glaucoma patients (higher intraocular pressure and suspected optic disc) The advantage of involving a fundus camera is also in the possibility of the retinal pathologies detection such as diabetic retinopathy or age-related macular degeneration as a secondary outcome of the study. However, the primary goal of the study is to detect glaucoma and ocular hypertension. This area is also supported by the Risk Factors Questionnaire and the Patient Education Questionnaire. All patients will be evaluated by University hospital Olomouc (FNOL) ophthalmology specialists who will evaluate data coming through the specifically designed FNOL telemedicine webportal from intraocular tonometers and fundus cameras. Suspected patients will be invited to the FNOL Eye Clinic for follow-up assessment using other modalities - perimeter, OCT, stationary fundus camera, etc. The secondary goal of the project is to create a database combining retinal images with intraocular pressure values, and data from other modalities in suspected patients who come to the FNOL for follow-up examinations. This goal will support the epidemiological study as well as it opens up the possibility of building a neural network over the database for easier classification of glaucoma patients in the future. As cognitive impairments (for instance Alzheimer's disease) can also be inferred with the above-described equipment, patients are also presented with a questionnaire to examine their cognitive performance. Data collected with use of questionnaires will be also part of the database. Consequently, presenting the tertiary outcome of the described study.
