Canine glaucoma

Canine glaucoma refers to a group of diseases in dogs that affect the optic nerve and involve a loss of retinal ganglion cells in a characteristic pattern.

Untreated glaucoma in dogs leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

The group of multifactorial diseases which cause glaucoma in dogs can be divided roughly into three main categories: congenital, primary or secondary.

There are rarely any symptoms in the early stages of the disease so regular eye checks by qualified veterinary professionals are important.

[4] Laser surgery is often performed to selectively destroy the tissue, ciliary body, in an effort to reduce aqueous fluid production.

These are used if dogs do not respond to maximal medical therapy, with previous failed guarded filtering surgery (trabeculectomy).

The ongoing scarring over the conjunctival dissipation segment of the shunt may become too thick for the aqueous humor to filter through.

And for Glaucomatous painful Blind Eye and some cases of Glaucoma, cyclocryotherapy for ciliary body ablation could be considered to be performed.
