Initiating prophylactic anti-glaucoma and anti-inflammatory treatment in the normotensive eye has been shown to delay the onset of glaucoma in a dog at risk by a median of 324 days.10 Client education and early intervention can delay vision loss and improve the quality of life for your patients. Glaucoma in dogs is always due to a decreased drainage of aqueous humor (AH)—increased production does not occur.
