Eye Allergy in One Eye That Isn't Improving
by Kelly
(Greenville, NC)
Allergies usually affect both eyes, so a red eye with constant yellow-green discharge in just one eye makes us wonder about other causes, such as dry eye, a foreign body behind the third eyelid, an eyelid or eyelash problem, or a blocked tear duct.
Ask your vet for a tear test, a stain test and, if needed, a referral to a veterinary ophthalmologist. Many of these causes are curable or controllable once identified.
