Pingueculum

Definition

A pingueculum is a yellowish patch or bump on the white of the eye, most often on the side closest to the nose. It is not a tumor, but an alteration of normal tissue resulting in a deposit of protein and fat. Unlike a pterygium, a pingueculum does not actually grow onto the cornea. A pingueculum may also be a response to chronic eye irritation or sunlight.

Symptoms

• Redness
• Irritation
• Inflammation
• Foreign Body Sensation
  

The symptoms described above may not necessarily mean that you have a pingueculum. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.

Treatment

No treatment is necessary unless the pingueculum becomes inflammed. A pingueculum does not grow onto the cornea or threaten sight. If it is particularly annoying, a pingueculum may on rare occasions be surgically removed, but the post-operative scar may be as cosmetically objectionable as the pingueculum.

Inflammed pinguecula can be treated with lubrication or other eye drops as needed.
