where are the brown spots exactly? How long have they been there? What is your race, gender and age? Any way you can post a picture?
I read your letter....What is your race, gender and age? Is there a pterygium that is starting to grow on the cornea (clear portion of the eye above the pupil) or are you mostly concerned about the sclera (white part of the eye) ?
if the reply panel you have is like mine, there is a little tree icon above near the smiley face.....use that button, do you see it?
