pseudotrop Posted August 24, 2010 Share Posted August 24, 2010 cloudy eyes can be caused by a bacterial infection Go here, you might be able to find what you're seeing and how to treat it. JBL online hospital It's been posted before, could be quite useful. Check the 'possible confusions' links too. Link to comment Share on other sites More sharing options...

Oh...probably...maybe It may NOT be cataracts though. Fish are different to mammals in that they have a spherical lens (remember cataracts is a LENS problem) and the lens protrudes through the iris a bit...so...if the cloudiness is in the centre of the eye and appears to be on the other side of or through the iris then its probably cataracts (true cataratcs are pretty rare in fish) However, its probably all academic. If the fish has had it for so long its probably never going to resolve Mike Link to comment Share on other sites More sharing options...
killiguy Posted August 25, 2010 Share Posted August 25, 2010 As Mike said the anatomy of the fishes eye is similar to ours Its important to distinguish between disorders of the cornea(outer covering of the eye) and disorders of the lens. The most common cause of an opaque eye in fish are trauma or infection of the cornea. Cateracts can happen in fish and are caused by similar problems to humans (nutritional deficiency,senescence etc)with UV light not being a problem as for us. Id say your fish has cateracts if the surface of the eye is clear. As Mike also said its a bit academic as I dont think you can put lens implants into a fish or do a corneal transplant if its a scarred cornea Link to comment Share on other sites More sharing options...
