Possibly you are making mistake in spelling, It is Pterygium. It is often observed as a part of allergic
illness. Do you have asthma, had
atopic dermatitis in the childhood or do you suffer from any allergy. Do Skin
patch test find out agent to which you are allergic. And get treated.
You might not get benefited by this, then you can
consult ophthalmologist and get a surgery -- diversion of growing end of the lesion.
Finally it is benign -- DO NOT WORRY IF YOU DO NOT DO ANYTHING, BUT GET CONFIRMED THAT IT IS PTERYGIUM.
