Hi. My 9mo old baby boy has a slightly raised white blemish on his eyeball under the eyelid. He rubs his eyes when he's tired, but he rubs the eye with the "spot" more. It's not a pimple-like bump. It almost looks like something got on the eye and didn't get off and the eye formed a protective "crust" to protect itself. I'm wondering if it's a cataract bcuz it's not actually on the lens, but under the eyelid. When he's looking at you, you can't tell it's there. You have to gently push back the eyelid to see it. Any ideas?
