My cat has recently developed a dark green ring around the pupil of his eye. Is this sign something wrong?

It is important to take your cat to the vet if you notice a sudden change in the appearance of their eye. A dark green ring around the pupil can be a sign of uveitis, an inflammation of the uvea, which is the middle layer of the eye. Uveitis can be caused by a variety of underlying conditions, including infections, autoimmune diseases, and trauma.

Common signs of uveitis are

- red or bloodshot eyes,

- cloudy vision,

- excessive squinting,

- pawing at the eye and eye discharge.

Treatment for uveitis depends on the underlying cause and may include eye drops, systemic medications, or surgery. To properly diagnose the cause further assessment including imaging and testing performed by a board-certified veterinary ophthalmologist may be recommended based on the severity of the inflammation.

To protect your cat's vision, it is important to have any changes in their eye appearance evaluated by a veterinarian as soon as possible.
