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.
