Pingueculum are very common in adults.
They consist of a fatty, elastic type of tissue. They stay relatively small but they do cause inflammation. The cause is not completely known, however smoke, wind, dust, contact lenses, dry eyes and even ultraviolet exposure to the sun are thought to be contributing causes.
The conjunctiva is a thin, clear layer of tissues that covers the white portion of the eye as well as the inside of the upper and lower eyelids. A pingueculum is thought to be degeneration or thickening of this tissue covering the white part of the eye.
Typically, pingueculum are positioned in the horizontal meridian on the front surface of the eye. They can be present on either side of the cornea, but they are more common on the nasal side.
Pingueculum are not a cause for alarm. Should a pingueculum become red or irritated, topical decongestants may be used to relieve the redness or the mild irritation that may result.
