What Is Glaucoma in Dogs?
Glaucoma is painful disease that occurs when the pressure inside a dog’s eye is too high. Normal intraocular pressure (IOP) is betwen 10 and 25 mm Hg but dogs with glaucoma have eye pressure exceeeding 25 mm Hg. If the pressure within an eye stays over 25 for an extended period of time it can cause permanent damage to the optic nerve at the back of the eye. If the optic nerve is damaged then permanent blindness can occur.

Symptoms of Glaucoma in Dogs
Dogs that have glaucoma are living in constant discomfort and even pain due to the high pressure in their eyes. Because of this pain, a dog may paw at its eye or rub it on the ground in an attempt to make it feel better. It may also hold an eye with glaucoma shut or excessively blink because of the discomfort.

If the glaucoma has been present for some time, a dog’s eye may appear to be bulging or larger than normal like an over inflated balloon. The enlargement may also cause issues with blood flow and cause excessive redness or inflammation on the part of the eye that normally appears white. In addition to the eye itself being enlarged, the black pupil in the center of the eye is sometimes dilated or enlarged due to glaucoma.
