if it is only one eye it is caused by mechanical damage. not to worry.
if both eyes are damaged the fish has to be brought in and treated as for dropsy.

Hi - I have looked everywhere to find treatment for a goldfish in my pond
that has popeye (http://www.slaterweb.co.uk/popeye.jpg for picture) but
cannot find anything. I can find treatment for tropical fish in an aquarium
but not pond fish - any help would be much appreciated.

Thanks - Terry
