Fish disease - Eye lesions

Eye problems in fish can have a long row of different causes from bacteria to poor nutrition. The symptoms of eye problems vary as much as the causes of the eye problems and include everything from cloudy eyes (which often are a result of bacterial infection) to exophthalmia pop eye and opaque lenses. Physical injury is also quite common.

Cloudy eyes are result of a bacterial infection even can be caused by fungus. Pop eye, formally known as exophthalmia, can be caused by vitamin A deficiency, tumours, bacterial infection, gas embolism and rough handling.

Pop eye caused by vitamin A deficiency can often be cured by an improved diet with more vitamin A. Pop eye caused by tumours or rough handling can be hard to do treat and it is unfortunately often up to the fish itself to try to recuperate from. Opaque eyes are caused by nutritional deficiencies. Improving  the diet and including a lot of vitamins in it can often help cure opaque eyes.
