Primary Open-Angle Glaucoma
Primary open-angle glaucoma (POAG) is a hereditary eye disease that leads to increased intraocular pressure and can cause blindness if untreated.
Detailed Description
POAG is caused by impaired drainage of aqueous humor in the eye, resulting in increased intraocular pressure that damages the optic nerve and retina. In affected breeds, including the Basset Fauve de Bretagne, a specific genetic mutation can lead to progressive vision loss and eventual blindness if not managed.
Common Symptoms
- Redness of the eye
- Cloudy cornea
- Vision loss
- Enlarged globe (buphthalmos)
- Eye pain
Management Options
- Topical intraocular pressure-lowering medications
- Surgical intervention (laser therapy, drainage implants)
- Pain management
- Blindness adaptation training
Frequently Asked Questions
Is POAG preventable?
Yes, through genetic testing and responsible breeding, the risk of POAG can be minimized in predisposed breeds.
What are the first signs of glaucoma?
Early signs include redness, cloudiness, and subtle vision loss, especially in middle-aged dogs.
