Texture analysis of retinal images oriented towards detection of neronal fibre layer
Gazárek, Jiří ; Jiřík, Radovan (referee) ; Jan, Jiří (advisor)
The thesis is focused on detection of local disappearance of the neural layer on retina in fundus-camera images. The first chapter describes the human eye physiology, the glaucoma disease and the analyzed data. The second chapter compares four different approaches that should enable automatic detection of a possible damage to the retinal neural layer. These four approaches have been tested and evaluated; three of them showed an acceptable correlation with the medical expert conclusions – the directional spectral approach, the edge based approach and the difference local brightness. The last approch via local co-occurrence matrices has not turned out to be informative with the respect to the issue concerned. Then a program for the automatic detection of the nerve fibre layer loss areas has been designed, realized and evaluated. This task is solved in the last chapter. A relatively good agreement between the medical expert conclusions and the conclusions detected automatically by this program has been reached.

Methods for texture analysis in ophthalmologic images
Hanyášová, Lucie ; Szabó, Zoltán (referee) ; Kolář, Radim (advisor)
This thesis is focused on texture analysis methods. The project contains an overview of widely used methods. The main aim of the thesis is to develop a method for texture analysis of retinal images, which will be used for distinction of two patient groups, one with glaucoma eyes and one healthy. It is observed that glaucoma patients don´t have a texture on the eye ground. Preprocessing of the images is found by transfer of the image to different color spaces to achieve the best emphasis of the eye ground texture. Co-occurrence matrix is chosen for texture analysis of this data. The thesis contains detail description of the chosen solutions and feature discussion and the result is a list of features, which can be used for distinction between glaucoma and healthy eyes. The method is implemented in Matlab environment.

Image database system for glaucoma diagnosis support
Peter, Roman ; Roleček, Jiří (referee) ; Kolář, Radim (advisor)
Tato práce popisuje přehled standardních a pokročilých metod používaných k diagnose glaukomu v ranném stádiu. Na základě teoretických poznatků je implementován internetově orientovaný informační systém pro oční lékaře, který má tři hlavní cíle. Prvním cílem je možnost sdílení osobních dat konkrétního pacienta bez nutnosti posílat tato data internetem. Druhým cílem je vytvořit účet pacienta založený na kompletním očním vyšetření. Posledním cílem je aplikovat algoritmus pro registraci intenzitního a barevného fundus obrazu a na jeho základě vytvořit internetově orientovanou tři-dimenzionální vizualizaci optického disku. Tato práce je součásti DAAD spolupráce mezi Ústavem Biomedicínského Inženýrství, Vysokého Učení Technického v Brně, Oční klinikou v Erlangenu a Ústavem Informačních Technologií, Friedrich-Alexander University, Erlangen-Nurnberg.

The Non-Compliance Phenomenon and its Influence on the Consumption of Drugs for the Diagnosis H.40 -Glaucoma
Kulovaná, Jana ; Lešetický, Ondřej (advisor) ; Loulová, Magdalena (referee)
Glaucom, one of the most significant opthamology problems, is the second most often reason of blindness.Conservative treatment is frequently used for the treatment.Currently in Czech Republic, the local applied preparates share more than 50 % of the total cost of all opthamopharmaceutics. Generally, the efficiency much depends on a patient compliance. A patient collaboration is very problematical mainly at chronic illness. The patient does not observe necessarily symptoms of illness. The aim of the diploma work is an assesment of an impact of non-compliance phenomenon (mainly at patient side) on antiglaukopharmaceutics and analysis of development of prescription of antiglaukopharmaceutics in last 10 years.

The educational Role of a Nurse in Caring for a Patients with Glaucoma.
HLÁVKOVÁ, Blanka
In my Bachelor thesis with the topic ``The Educational Role of a Nurse in Caring for Patients with Glaucoma{\crqq} I dealt with the issue of glaucoma disease, education, and what the role of a nurse in this issue is. The theoretical part is focused on the term glaucoma, how it is shown, diagnosed and treated. I have described very valuable advice for patients with this disease. Another point of this theoretical part is education focused on the topic of what the patient should imagine under this term and what education brings from the point of view of the nurse. The Practical part is focused on the quantitative and qualitative survey. The objective was to make a survey of the intervention into the nurse´s educational activity during the care for a patient suffering from glaucoma disease.
