Computer‐assisted analysis of the electro‐oculogram

Abstract

A method of acquiring and analysing electrooculogram signals was developed using computeraided techniques. The repetitive nature, characteristic shape and spectral properties of the electro-oculogram are used in the automated analysis, enabling the retinal resting potential to be investigated. Online computer-aided automatic analysis of the electrwculogram is efficient, reliable and accurate. Automated analysis produced results that have a highly significant degree of correlation (P<O.OOl) with the results obtained manually from strip chart recording of the electro-oculogram signals. The increased accuracy of the automatic analysis system demonstrates a significantly reduced (McNemar's Test) false positive rate in classifying abnormal results on the basis of Arden ratio. The computer-aided analysis system offers a useful clinical means of measuring the electrooculogram for diagnostic and research purposes.
