Well, generally speaking, pinguecula occurs on the lining covering the white part of the eye. When it occurs, elevated spots which may be white or yellow will appear near the eye corners. And when it occurs, you may not need to try any treatments to treat it, for they can just disappear by themselves one week. Of course, lubricating eye drops can be effective too. Anyway, you can just have a try.
A pinguecula is a small and yellowish nodule on the surface of the corners of the eye, and it can appear on either side of the cornea or on the nasal side. It may increase in size. Frequent exposure to ultraviolet light, toxic vapours, dust, wind, salt water spray can cause pinguecula. Those who suffer from pinguecula can feel as if there is a foreign object in the eye.
