Pinguecula and pterygia are growths on your eye’s conjunctiva, the clear
covering over the white part of the eye.. They often appear on the side of the eye near your nose.
Pinguecula are deposits of protein, fat, and calcium, and look like a yellow spot or bump .
Pterygium are growths of fleshy tissue that may start as a pinguecula. It can remain small or grow large enough to cover part of the cornea. When this happens, it can affect your vision.
Symptoms of pinguecula /pterygia can range from mild to severe. They include:
Both pinguecula and pterygia are believed to be caused by a combination of dry eyes and exposure to wind, dust, and ultraviolet (UV) light from the sun.
To prevent pinguecula/pterygia we focus on the underlying causes:
Many patients with pinguecula or pterygia do not need treatment.
However, treatment is initiated when:
The first line of therapy for pinguecula that are causing symptoms or increasing in size is the same as the treatment for dry eyes. If there is redness and/or significant irritation then steroid drops are used temporarily.
For patients who continue to have symptoms despite the above treatments and for patients for whom the pterygium is increasing in size, surgical removal is recommended.
The surgery is very simple, safe and effective.
