Dr. David Kisling returns as a guest blogger to shed some insight on Pinguecula.
Small bumps that seem to suddenly appear on the white part of the eyes often bring concerned patients into the optometrists’ office. Most often, doctors will diagnose these bumps as pinguecula. These growths frequently have a yellowish discoloration and show up over the white of the eye closest to the nose. If you have been diagnosed with a pinguecula, don’t despair! Almost everyone past the age of 70 or 80 will have some signs.
What casuses Pinguecula?
Ultraviolet radiation from sunlight causes the conjunctiva, clear tissue that covers the white part of the eye, to accumulate abnormal elastin and collagen. Over a number of years, the result is an elevated bump of compromised tissue. Because the conjunctiva lacks the protective layer of keratin on the skin, these changes occur more rapidly over the white part of the eye.
Pinguecula are always benign growths and do not turn into any form of invasive eye cancer. They tend to be very slow growing over the course of years. Usually individuals gain acute awareness of their presence when some form of irritation makes them become much more apparent. Pinguecula are almost never surgically removed.
Take preventative steps for your family.
- Start children with sunglasses at an early age. When you think of sunscreen think of sunglasses.
- Lower UV exposure. Peak outdoor exposure hours are between 11:00 a.m. to 3:00 p.m.
Other conditions, some serious, can also cause similar appearances over the white part of your eyes. It is important to schedule a visit to evaluate any growth you see on yourself or family members. Once the diagnosis of pinguecula is made you can relax (in the shade preferably) knowing your eyes are not at risk for a serious condition.
