A cat's marble-like eyes are a fascinating sight to behold; however, if they're not perfectly symmetrical, it's enough to drive any cat parent a little cuckoo. Should you panic if you notice something different in your feline's enchanting gaze? Most likely not, but it's always better to err on the side of caution, even when pertaining to creatures with nine lives.
How The Cat's Pupils Normally Dilate
The cornea that covers the pupil is the point where light passes through the eyes and onto the retinal nerves, enabling vision. According to the intensity of the light, pupils get bigger or smaller. Cats have extra rods on their retinas, which give them their ability to see better in darkness. If you've ever noticed your cat's pupils expanding right before a big jump or major attack, that's to allow all possible light through the cornea, so it can be transformed into electrical signals the brain interprets and acts upon. A cat's eyes aren't just dazzling spectacles of light and color, they're precision instruments the animal needs for survival, even if the only jungle they occupy is your living room.
What Anisocoria Looks Like To You
The dilation process isn't complete in one eye when a cat is dealing with anisocoria; thus, the two pupils will not be the same size. One may seem very much smaller or very much larger, but they definitely won't match. Initially, you may think you're seeing things, though after a closer inspection, it will become obvious that something doesn't coordinate between the two eyes.
The Possible Causes Of Mismatched Pupils
There are a number of situations that lead to this problem of the eyes in felines, but when it's a seemingly sudden case of anisocoria, you should immediately contact an animal hospital. Most of the time, mismatched pupils aren't an indication of a serious condition and the distortion can actually go away on its own, depending on the cause, which may or may not be any of the following:
- An injury to the eye itself
- Nerve damage or injury
- A birth defect
- Age-related atrophy
- A virus, infection or, in rare cases, cancer
Remedies for anisocoria range from simple drops to complex surgery if the underlying cause warrants action. Hopefully, your flirtatious or ferocious feline, whichever the case may be, won't need much of a medical boost to return to normal, but this eye imbalance needs to be checked out by a doctor, no matter what.
Your cat's eyes may be mesmerizing, spooky, or even a little crossed and goofy, but no matter what, you want to make sure those eyes are healthy. If you notice any anomaly or suspect something is amiss, make an appointment at your favorite animal hospital right away, where a prompt investigation will ensue. If it's anisocoria, the veterinarian will find out what's causing it and know what treatment(s), if any, are needed. Contact an animal hospital like Norwin Veterinary Hospital to learn more.
