'Cherry Eye'

Cherry eye is a condition some people may be familiar with. It is actually a prolapse of the nictitating membrane. What?! Those are a lot of technical terms so let’s break it down. The nictitating membrane, also called the third eyelid, is a part of the eye that helps keep the cornea moist and protects it from damage.  If the tissue that holds the third eye lid in place weak the lacrimal gland will prolapse (or pop out of place). This creates what we know as cherry eye. The name likely came because it looks like a little red cherry sitting in the corner of the eye.

Why do we care about cherry eye? If left untreated it can lead to the eye not getting adequate moisture which will then lead to dry eye. (A condition we discussed a couple of weeks ago.) A long time ago, corrective surgery involved removing the gland all together. This turned out to not be the ideal procedure as it led to a severe decrease in tear production and then dry eye developed. Treatment now includes tacking the gland back in place.

Although this is not an emergency, it is recommended to have the gland replaced to normal position before long term damage to the tear duct and secondarily, the eye, occurs. Consulting with your veterinarian will determine the best course of action for your pet. For more information on this condition please visit the following website here.
