Glaucoma in Labrador Retrievers: An Emergency Regardless of the Cause

Not as a primary, inherited condition the way it is in breeds like Cocker Spaniels. When it occurs in Labradors, it's usually secondary to another eye problem like advanced cataracts, chronic inflammation, or injury.

Advanced, untreated cataracts, chronic eye inflammation (uveitis), lens luxation, or significant eye trauma are the realistic underlying causes, each of which can block the eye's normal fluid drainage and cause pressure to build.

A red, painful-looking eye, cloudiness or a bluish haze, an enlarged or bulging appearance, squinting, and sometimes a dilated pupil that doesn't respond normally to light. Sudden onset is typical.

Yes, regardless of whether it's primary or secondary, glaucoma causes rapidly rising eye pressure that can permanently damage the optic nerve and cause blindness within twenty-four to forty-eight hours without treatment.

Emergency treatment focuses on rapidly lowering eye pressure with medication, followed by addressing the underlying cause if secondary, and in some cases, surgery. Vision may or may not be recoverable depending on how much damage occurred before treatment.

If the underlying cause, like advanced cataracts or chronic inflammation, is present in both eyes, the unaffected eye is at real risk and often needs preventive monitoring or treatment.

The best prevention is managing underlying eye conditions, like cataracts or uveitis, promptly before they progress far enough to interfere with normal fluid drainage and trigger secondary glaucoma.
