A Pingeculae is a thickened, slightly raised and yellowish are, usually located at 3:00 or 9:00 on the white of the eye, the conjunctiva. This does not cause your dry eye, but it can cause feelings of foreign body sensation or irritation. It is usually caused by sun or UV exposure, or chronic irritation. Sometimes it can extend onto the cornea, in which case it is called a pterygium. It is not dangerous, nor malignant, and it is very common. Treatment is lubrication, by drops or ointments. If the area becomes inflamed, topical steroid drops can be used short term. This area is prone to dryness because it does not wet as easily with tears. It is not dangerous, you should not worry.
