Corneal tumours in goldfish

The cornea is the transparent window at the front of the eye and because fish have no eyelids, it is more prone to physical damage. It has a complex cell structure and is covered with a transparent thin layer of skin. Tumours of the cornea are not uncommon in goldfish, and many are spindle cell tumours which are common although the eye is disproportionately affected. The appearance and colour of these tumours can vary significantly. Treatment options are limited and although cryosurgery has been effective in some cases, many are presented at an advanced stage and enucleation (surgical removal) is usually necessary.
