EYE FLUKE DISEASE
a disease caused by the metacercaria of strigeid trematodes (Diplostomum). The life cycle involves a snail, fish and the final host, a bird. Larval flukes invade the fish through the gills and reach the eye capillaries through the blood stream. Blindness can result. Symptoms include cloudy eyes and popeyes but these also have other causes. Small white cataracts may develop. Wild snails should be avoided in the aquarium. Also called diplostomiasis
