Pingecula and Ptyergium
A Pinguecula is a raised area that often appears whitish-yellow and is usually located on either side of the white part of the eye. This is not cancerous, or a cataract, but should be monitored.A Pterygium is very similar to a pinguecula except that it is located either totally or partially on the cornea (the clear window of the eye), and does offer far more threat to your sight.
What are the causes?
EXPOSURE TO SUN, WIND, DUST, POLLEN, POLLUTION
Increased exposure causes irritation to the eye. Just like a callous on your hand, your body reacts by forming a thickened tissue area to protect itself from these irritants.
Is there any treatment?
PROTECTION FROM SUN & WIND, UV SUN PRESCRIPTION AND KEEP MOIST
Since we can not totally remove ourselves from the causative factors, we must minimize our exposure to these irritants to decrease the effects of them.
*** The Best Treatment is Prevention ***
Since pinguecula and pterygium are most often caused by exposure to the sun’s ultraviolet rays, wind, dust or other irritants, Dr. Baron suggests that it is best to limit exposure to all of these by wearing a good pair of sunglasses that provide complete protection for your eye against all potentially dangerous rays. A good rewetting drop helps to eliminate some of the irritation and helps to keep the eye moist to reduce friction of the lids while blinking (Do not use Visine/Murine type of products). This can also be accomplished by adding a UV-400 coating to your regular prescription lenses. Goggles are highly recommended if you work in an area that is dusty or exposes you to chemical irritants.
