My cat's cloudy eye and prominent third eyelid returned. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Korat | Male | neutered | 13 years and 11 months old | 9.6 lbs

Hi, Beau's right eye had a cloudy len with blood vessels. The vet diagnoised it as non-ulcerated corneal edema. The vet prescripted an eye ointment. The eye cleared up for a few weeks but the haziness returned despite continual treatment. His third eyelid is also more prominent. What could be the cause? Hes an indoor only cat so FIV is unlikely. Thank you.

If there was no ulcer present, it's possible that the corneal edema is related to infection or glaucoma. There are a few inherited diseases that can cause corneal edema as well. If the current treatment is no longer helping you should recheck with your veterinarian. You may also want to ask about referral to a veterinary ophthalmologist who might be able to better determine what is causing the edema.
