Pingueculae are very common in adults. They appear as yellow nodules in the conjunctiva (the white part of our eyeball) These nodules sometimes increase in size, and inflammation is common. 
If this condition bothers the bearer, medications can be prescribed to ease the symptoms.
When the pinguecula grows it can invade the cornea, usually on the nasal side of the eye. In order to avoid further invasion of the cornea, surgery is recommended.

This technique reduces the possibility of recurrence by 95%.
