Abstract
An ophthalmoscopical survey on Collie Eye Anomaly (CEA) was conducted in 27 collies (220 between 1969-1972 and 50 between 1987-1991) kept in the Kanto district of Japan. No difference was observed in total incidence of the anomaly (88.0%) between the two survey periods, which agreed with reports in other countries. The number of severe cases significantly decreased in the second survey as compared to the first, suggesting that there may have been effective genetic selections against CEA, although the genes responsible for CEA remain incorporated in the collie breed genome.
