了解狗狗的青光眼

Glaucoma arises when intraocular pressure (IOP) exceeds the tolerance of the optic nerve. In dogs, normal IOP ranges from 10–25 mmHg. Any sustained increase damages the retina and optic nerve.

Types:

• Primary glaucoma: Inherited abnormalities of the drainage angle, common in Cocker Spaniels, Chow Chows, and Beagles.
• Secondary glaucoma: Triggered by other ocular diseases like uveitis, cataract complications, or intraocular tumors.
