Žmogaus akipločio tyrimas / Evaluation of human visual field

Nakutytė, Aušra 03 August 2011 (has links)
Bakalauro darbas skirtas žmogaus akipločio analizei ir jo tyrimui. Darbą sudaro trys skyriai. Pirmame skyriuje analizuojami pagrindiniai akiplotį nulemiantys veiksniai bei akipločio defektai. Antrame skyriuje – aptarti dažniausiai naudojami akipločio tyrimo metodai. Praktinėje dalyje analizuojami eksperimento metu gauti akipločio duomenys. Tyrimo metu pastebėta, kad skirtingų spalvų chromatinės akipločio ribos skiriasi. Eksperimento metu paaiškėjo, kad akiplotis siaurėja tokia seka: baltos, mėlynos, raudonos ir žalios spalvos. Akipločio ribos spalvotiems stimulams skiriasi priklausomai nuo to, ar stimulas stumiamas iš centro į išorę, ar atvirkščiai (pirmuoju atveju akiplotis didesnis. / The subject of the Bachelor’s work is to analyze and investigate the visual field. The work consists of three sections. The first section gives the analysis of the main determinants and defects of the visual field. In the second section, commonly used methods of the visual field investigation are studied. In the practical part of the work, the data of the visual field investigation are analyzed. It was noticed that chromatic visual thresholds of different colours differ. The experiment showed that the field of vision narrows in the following sequence: white, blue, red and green colors. Visual thresholds for color stimuli vary depending on whether the stimulus is moved from the center to outside or vice versa (the visual field is bigger in the first case.
