A “pterygium” is a fibrovascular growth which grows from the nasal portion of the white of the eye (the sclera) and crosses centrally over the cornea.  Other names for a pterygium include “carnosidad” and “nina”.

Typically it starts as a “pinguecula”, which is an elevated mass of white tissue over-lying the sclera. Except for occasional redness, pinguecula are typically white or yellow plaques on a white background, so they can be hard to see. As a pinguecula grows, it turns into pterygium.

A pterygium may be the cause of several different complaints. It can block the vision if it grows larger, but even when small it can induce warping of the vision with astigmatism. Pterygia often cause persistent redness and irritation of the eye. They can enhance dryness and foreign body sensation. They can be very uncomfortable and unsightly as well.

Traditional methods of pterygium removal have shown recurrence rates in some studies in nearly half the patients having the surgery. Dr. Klein has several innovations he employs as part of his IsoWhite pterygium removal surgery which reduces the chances of a pterygium growing back after surgery drastically.  There is much more information on Dr. Klein’s website for pterygium patients at
