Using of visually evoked potentials for assessment of visual acuity
Hnízdilová, Bohdana ; Svozilová, Veronika (referee) ; Mézl, Martin (advisor)
In this thesis is described the usage of visual evoked potentials. The theoretical part describes how evoked potentials are measured and recorded. In this thesis is described the usage of evoked potencials in ophtalmology to determine visual acuity. Furthermore, it explains flash stimuli, onset / offset stimuli, pattern-reversal stimuli, and their responses. Practical part deals with evoked response to pattern-reversal stimuli. Signals from encephalogram electrodes and lux meter were measured using Bitalino device. The signals are processed and evaluated by semi-automatic software, where individual sections of the signal are selected by the user. The output is the epoch of the selected section.
