My senior dog has a white spot in his pupil. Is it a cataract?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Male | neutered | 9 years and 8 months old | 25 lbs

My Boston Terrier is 9, and a few days ago I noticed a white spot in his pupil. It seems to come from behind his iris and into the pupil. It's doesn't look like it's on the surface of the eye. His eyes have not been getting cloudy. Do you have any idea of what it could be?

Hello I can't tell exactly what is going on with Jack but it could be a type of cataract forming in his lens causing that spot. If he isn't squinting, does not have any eye discharge, redness and/or cloudiness you can monitor that spot for now and contact you veterinarian about how soon they would want to examine his eye more closely with a specific light and lens.

    You have been asking this question repeatedly. This appear to be a faint scar from an old injury. It is nothing to worry about at all. It will not impair his vision or cause any long term problems. If you are that worried you need to take Bruno to your vet for an exam so they can look at the eye with an ophthalmoscope.

    Even though your pictures are excellent quality it can be very difficult to tell exactly what is going on with an eye without being able to examine it in person using lights. It looks like Nice has corneal edema on the left, or fluid within the cornea. This could be from an infected corneal ulcer, glaucoma, or corneal endothelial disease. I would guess your veterinarian saw an infected corneal ulcer. and that the medications helped the infection. Since there is still edema the infection may still be present, or this may be a more permanent change. As long as the eye is not infected and the pressure is normal surgery might not be necessary. It's hard to know what the noise you're describing might be without being able to hear it, but I would be suspicious of a reverse sneeze. Dogs can reverse sneeze due to allergies or other nasal disease although it usually is not anything to be concerned about. I doubt any cause of a reverse sneeze would be related to the changes in Nice's eye.

    I am sorry to hear about your dog. It is tough to evaluate eyes with a photograph but it almost looks like she could have an abscess or foreign body in her cornea. I would recommend bringing her in to her vet as soon as possible, as eyes are best treated early to have the best chance at preserving vision and the eye! The vet will examine the area and with an in-person exam and special tools for examining the eye can better determine the problem and how to proceed with treatment.
