My cat has over the past year developed a slowly growing brown discorloration in a ring shape around her pupil.It started when she had a yellowish,green glob in the inner corner of her eye.I removed it and within a few days the ring started to develope.Should I be concerned,she in all other aspects seems healthy.?
I am always concerned about problems with the eye. This should be checked out by the vet to be on the safe side. It is hard for me to give you an idea of what it might be by your discription. I would need to see the eye. vetcare
