Also Known As – Pop-eye - Exophthalmia

Caused By – Many diseases and infections

Introduction

Exopthalmos or “pop-eye” in fish is the most common ophthalmic pathology and can be the result of many diseases, injuries and infections.

Potential causes include trematode infection when flukes reside subretinally, Infectious Pancreatic Necrosis, Infectious Haematopoietic Necrosis, Viral Haemorrhagic Septicaemia, Icthyosporidium infection, Tuberculosis, Aeromomas spp. and Pseudomonas spp. infections, Vibriosis, renal disease

Distribution

Signalment

Clinical Signs

The eye/s of affected fish appear to be larger and protruding from the skull.

Diagnosis

The condition can be diagnosed clinically upon visual examination of the fish. Underlying diseases may require serology, bacteriology, parasitology or other investigative techniques.

-Non-infectious causes include [[Gas Bubble Disease]], renal disease and ammonia toxicity.

 ==Signalment==
-Any type of fish, commercial or ornamental, can be affected.
 ==Clinical Signs==
-The eye/s of affected fish appear to be larger and bulging/protruding from the head. Traumatic injury often occurs as a result.

 ==Treatment==
-Treatment is highly dependent upon the cause and may or may not exist.
-Removal of excess gas may resolve minor [[Gas Bubble Disease|gas bubble disease]] or movement to a different tank may allow recovery from ammonia toxicity. Bacterial causes may respond to antibiotic therapy. Treatment is usually ineffective once significant damage is done to the globe.
 ==Control==
-Biosecurity and disease prevention protocols are imperative for control of infectious causes of exopthalmos. Traumatic injury can be prevented by environmental design.
