| Summary: | In this paper, an analysis of the Electroretinography response for both flickering and current stimulations is presented. To perform the analysis, data from 6
subjects was collected. The subjects underwent two types of
stimulation: (1) flickering, and (2) current. Electrodes with two different inner diameters (0.4 cm) and (0.7 cm) were used to record retina responses. The configuration of electrode connection followed ISCEV standard protocol for ERG responses. The electrodes were placed on the forehead and inner and outer canthus of the eye. Data analysis using MATLAB produced a graphical illustration of flicker and current stimulation in both, time and frequency domain. Results show amplitudes at 12.56 Hz and 50.26 Hz. We conclude that these frequencies correlate with retinal functions and may serve as a physiological indicator. Future works may use these results to improve the evaluation of retina function. |
