AVIAN EYE DISORDERS
Birds can suffer from many different eye disorders. They can be due to an eye injury, or possibly an infection to the area. Occasionally, eye disorders are symptoms of another underlying medical problem. Therefore, if your bird has an eye problem, it should be considered serious and you should consult a veterinarian to rule out any major internal disease.
SYMPTOM AND TYPES
Conjunctivitis, a common eye disorder, is usually caused by bacteria and can be identified as red and swollen eyelids, and may lead to photosensitivity (avoidance of light) in the bird. Conjunctivitis is also a symptom of many other medical problems, including respiratory infections.
Uveitis causes an inflammation of the inner parts of the eye. However, it is commonly associated with symptoms of other internal diseases in the bird. This particular disorder needs to be treated quickly to avoid cataracts from forming.
Cataracts develop in the bird’s eye when there is a deficiency in vitamin E, an infection with encephalomyelitis, or even from continuous exposure to some artificial lights.
Marek’s disease is a particular type of eye disorder that is caused by a viral infection. This medical condition can lead to irregularly shaped pupils, iris problems blindness, and can progress into cancer. Vaccination can prevent this eye disorder from occurring. However, a bird that is already infected with the virus, cannot be cured.
Avian Pox is another eye disorder which is found in birds, and is due to a viral infection. Though it is a generalized disease, the eye symptoms include swelling of the eyelids with blister-like formations, and partial or total loss of vision. However, the eyeball is not affected by the infection and the vision usually returns after the infection is treated.
