Abstract: Fish eyes syndrome is often one of the causes which induce difficulties in the life of both wild and cultured fish. The clinical fish eye syndrome is either local or systemic. The most common syndromes affecting wild fish are exophthalmos (pop-eye) and cataracts while those recorded in cultured one are exophthalmos, cataracts and enophthalmos (sunken-eye). The syndrome is associated with various infectious causes such as parasitic, chemical, mechanical, traumatic and hormonal imbalance. The epidmiolgy of these syndromes depends on the cause of infection of the eye in both wild and cultured fishes of all species and ages. Also, the diagnosis of these syndromes depends on: case-history, behavioral abnormalities and clinical examination (clinical signs and laboratory diagnosis). Histopathological examinations of eye syndromes affecting wild and cultured fish are graded from inflammation in acute form (traumatic causes) to cataracts and keratitis in chronic form (parasitic causes), retro-retinal gas bubbles (GBD). Prevention and control of fish eyes' syndromedepends on strict hygienic measures including the use of profilactic treatment of parasitic and biological control. Treatment and removal of the causative agent are considered to be the most important factor in treating these diseases. In conclusion, eye affection syndrome is a group of non specific clinical signs which are associated with various infectious and non infectious diseases and the best approach to occular disease is the prevention or avoidance through either strict hygienic measures or treatment and removal of the causative agent.
