My dog has a brown spot on her eye. Is it pigmentary keratitis? Help!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. In pugs, this is a normal thing to see. There is increased pigmentation (melanin) deposited on the eye. Pugs can develop pigmentary keratitis, in which a dark film develops over the eye itself. This does not cause any pain and unfortunately there is nothing you can do to make this go away or slow down the progression. If the eye becomes irritated, you can use steroid drops. Something that a vet would need to prescribe Dexter after examining him. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I do not see anything alarming in these photos. If you are worried the darker pigment on the inside corner of the white part of the eye, that can be normal in some breeds. Corneal hyperpigementation is usually a result of chronic rubbing. It usually causes no problems long term. If you notice any redness or mucoid discharge, or if he does not want to keep eye open, then i would have him check by your vet.

Thank you for submitting your question regarding Kalua. This is a normal pigment change that some dogs will develop. Some will get it on the outer edges of the eyes as well. If he starts showing signs of pain such as squinting or tearing or if the pigment extends over the colored portion of his eye, then he will need to see his veterinarian. Otherwise, I do not see any reason for concern. I hope this information helps!

A thorough ocular exam is needed in these cases to define the problem. However, most common is pigmentary keratitis, or exposure keratitis. This is not usually reversing, However use of a steroid called dexamethasone can be somewhat helpful. Best of luck and thank you for using Pet Coach.

You should always have something like this checked out by your vet in person. A special ophthalmoscope is needed to check the eye. My best guess is that this is an iris (uveal) cyst. If this brown spot moves around in the eye (floating) it is probably an iris cyst. If it is stationary and does not move, then it may be a cancer. This is not something that can be diagnosed over the internet.

Thank you for contacting PetCoach with your question about Ellie. The pigmentation can grow over time. I will put a link below to an article as to what this could be. If this is pigmentary keratitis, the underlying cause needs to be diagnosed so it can be treated correctly. Even if this was a melanoma, yes they are usually benign in dogs. In fact, 80% of them are benign. If it was melanoma, it could be destroyed with a laser since it's small. Have her see a veterinary ophthalmologist before getting too worried about it. Best of luck. https://www.northwestanimaleye.com/pigmentary-keratitis.pml

Hi there and thank you for using pet coach to address your concern. Previous eye trauma can lead to scar tissue formation on the cornea, which can sometimes become a dark pigment. As long as the eye is not red and Otis does not seem to have eye pain, I would hust monitor this for now. If it becomes larger or new symptoms develop, I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
