A pinguecula is a change in the thin conjunctiva that covers the surface of the eye. In this episode of A State of Sight, Isaac Porter, MD explains the causes of pinguecula, describes the problem in detail, and discusses possible treatment options.

Usually, we believe that a pinguecula forms when the eye is exposed to UV radiation from sunlight. They may be seen more frequently in people who work outdoors and in those who live in areas closer to the equator. This exposure causes changes in the conjunctiva similar to a growth that thickens the conjunctiva over the white part of the eye between the eyelids. This growth is not a form of cancer, and it is much more common than the types of cancer that can occur in the same location on the eye, including squamous cell and melanoma.

If a pinguecula becomes large or inflamed, it can cause irritation that may be manged with artificial tears or prescription drops. Most often, they do not cause any problems and do not require treatment.
