Within the eye, the production and drainage of fluid is precisely balanced to maintain a constant pressure. Glaucoma occurs when this balance is disrupted and pressure within the eye increases. Symptoms include pain, eye redness, increased tear production, a visible third eyelid, corneal cloudiness, dilated pupils and in advanced cases, an obviously enlarged eye.
Call your veterinarian immediately if you are worried that your dog might have glaucoma because delaying treatment can result in blindness. Treatment may involve a combination of topical and oral medications that decrease inflammation, absorb fluid from the eye, lower fluid production within the eye and promote drainage of fluid from the eye. Surgery may also an option in some cases.
