Normal Human Electro-Oculogram
Data Collection
Summary
Study start date: February 1, 1997
Actual date on which the first participant was enrolled.Electro-oculograms (EOGs) will be recorded in volunteers of different age groups with normal visual function. The fast and slow oscillations of the EOG will be studied. For the analysis of fast EOG oscillations, peak-to-peak amplitude (micro V), peak-to-trough ratio, and phase (degrees) will be measured. The analysis of slow EOG oscillations will include measurements of the ratio of light peak to dark trough (Arden ratio), implicit time (latency) of the light peak (ms), and amplitude of the dark trough (micro V).
