Signs Of Eye Disease


PAIN may cause squinting, sensitivity to touch and increased irritability. Other signs include sensitivity to light, loss of appetite, lethargy and whining. The most painful eye conditions are glaucoma, corneal injuries and ulcers, uveitis and keratitis.


A clear colourless discharge is tears

A yellow-green discharge usually means infection


Damage to the surface of the eyeball (cornea) leads to the accumulation of fluid (corneal edema), causing cloudiness. Changes to the lens inside the eye cause a cloudiness within.

Redness Or Inflammation

The conjunctiva and the white of the eye becomes inflamed for a variety of reasons. If the cornea itself is red, there is bleeding or the growth of blood vessels in response to previous damage.

Visible Third Eyelid

The third eyelid protrudes naturally in some breeds but also when protection is needed. It may also protrude because of pain or as a sign of some neurological disorders. In some flat-faced breeds it may fold over on itself.

Tear Overflow

Tears may be produced in excess as a response to allergic irritation, physical irritants or simply wind in the face. Overflow also occurs when there is poor tear drainage from the eyes into the nasal cavity.

Bulging Or Sunken Eye

The eye may bulge because it has increased in size or there is pressure behind the eye. It may appear sunken when there is pain or when it has collapsed.

Crust Or Inflammation Around Eyer

A crust may develop because of a problem within the eye socket itself but also because of skin conditions that manifest themselves around the eyes.

Deterioration Of Loss Of Vision

There are both inherited and acquired causes of reduced or lost vision. The primary cause may be in the eye or in the brain.
