So I recently noticed 2 gray dots on my iris. They don't hurt at all, and i don't feel them. However, I do have a little reddning of the eye due to me rubbing it (I have allergies). It doesn't obstruct my vision at all and I do not have any trouble looking a bright lights. Could this still be corneal ulcer or is it something else? I could provide a picture if needed.
I would say this is most likely not a corneal ulcer as you would definitely have pain. if you have pics that would be great but my first thought is you have a nevus ( freckle) on your eye. We can get them anywhere. Some people have them on their iris and some people even have them in the back of their eye. Just like any other spots as long as they do not turn red or change it is harmless.
If there is no pain you dont have a corneal ulcer. They are excruciating. If you feel these have suddenly appeared you could go to an optician or your doctor and ask them to take a look.
