The Question
“Is there a way for a vet to check a cat’s range of vision? We adopted Gianni at 8 weeks from the shelter where he was being treated in isolation for a severe eye infection. As a nurse, I agreed to continue his treatment because he was the only long-haired haired available and he needed me.
He is 3 years old now and still has frequent eye infections in his left eye, even though he is an indoor cat. I wonder if he has permanent damage because he seems to have trouble
finding treats or bits of fresh chicken I drop for him right in front of his face. Could he be far-sighted? He doesn’t seem to be totally blind.” – Loretta
Quick Info about Gianni
Hi Loretta,
What a compassionate choice you made to give Gianni a chance when he needed it most. Cats who have had severe eye infections early in life, especially those affecting the cornea, conjunctiva, or deeper structures, can indeed develop some degree of lasting vision impairment. Scarring, chronic inflammation, or damage to the corneal surface can all interfere with how clearly light enters the eye, much like looking through a foggy window.
Veterinarians can evaluate a cat’s vision in several ways during a clinical exam. Simple tests include observing how the cat navigates a room, tracking a cotton ball tossed nearby (since it falls silently and tests visual tracking rather than sound), and checking the menace response, where a gentle hand movement toward the eye should trigger a blink. More specialized exams involve assessing the retina and optic nerve with an ophthalmoscope or referring to a veterinary ophthalmologist for advanced testing such as electroretinography. These tools help determine whether the limitation lies in the eye’s surface, the lens, or the deeper structures responsible for transmitting visual information to the brain.
From what you describe, Gianni may have reduced close-range vision, which makes it harder for him to spot small treats right in front of him. Using larger, more aromatic food rewards or placing them in a contrasting dish may make it easier for him. Because he continues to have recurrent infections, I recommend having him examined by your veterinarian, and if possible, a referral to a veterinary ophthalmologist. This will help assess both his current visual capacity and whether there is an underlying condition that can be managed to improve his comfort and protect the vision he has.
Sincerely,
– Dr. Paola
