Automated measurement of the electro-oculogram for clinical use.
A method of automated measurement of the EOG amplitude is described. Its main advantages are as follows: 1. The mean of amplitudes, at a series of time dots within a single EOG deflection recorded with DC-amplification, are automatically measured and printed out. 2. Artifacts due to blinks, overshoots or other irregular eye movements are automatically eliminated. 3. A base line drift is automatically compensated. The L/D ratios obtained in 80 eyes with this method were essentially equal to those obtained by a manual measurement (correlation coefficient 0.9905).
