Pinguecula
Pinguecula (pronunciation: pin-GWEK-yoo-lah) is a common type of eye condition that appears as a yellowish, slightly raised lesion on the conjunctiva, the clear surface of the eye. It is often found near the cornea, on the nasal side of the eye.
Etymology
The term "Pinguecula" is derived from the Latin word "pinguis", which means fat or grease. This is in reference to the appearance of the lesion, which is often yellowish and slightly raised, resembling a small deposit of fat or grease.
Symptoms
Common symptoms of a Pinguecula include eye irritation, eye redness, and a feeling of having something in the eye. In some cases, the Pinguecula can become inflamed, a condition known as Pingueculitis.
Causes
The exact cause of Pinguecula is unknown, but it is believed to be related to exposure to ultraviolet light, dry eye conditions, and dust.
Treatment
Treatment for Pinguecula often involves the use of lubricating eye drops or ointments to relieve symptoms. In severe cases, or when the Pinguecula interferes with vision, contact lenses, or is cosmetically bothersome, surgical removal may be considered.
