Common Eye Diseases and Disorders - Pterygium & Pinguecula

Pterygium and Pinguecula are growths on the conjunctiva (the thin membrane that covers the white part of your eye).  Both types are believed to be caused by dry eye and environmental elements.

	A pterygium is a growth of fleshy tissue on the conjunctiva that can extend over the cornea.

A pinguecula is a yellowish patch or bump on the conjunctiva.  It most often occurs on the side of the eye closest to the nose.  It is similar to a callus on the skin.  A pinguecula does not grow onto the cornea.

What are the symptoms?

Symptoms of both diseases can range from mild to severe and can include:

• Redness and/or inflammation
• Blurred vision
• Irritation
• Dryness
• Itching
• Burning
• Gritty feeling
• Feeling of having something in your eye

What is the treatment for Pterygium and Pinguecula?

When a pterygium or pinguecula becomes red and irritated, lubricants such as artificial tears, eye drops, or ointments may be used to help reduce swelling.  They can be removed surgically if they grow large enough o threaten sight or cause constant discomfort.

Can these diseases recur?

Pterygium and pinguecula can return.  To help avoid recurrences, it is best to limit exposure to environmental factors that can contribute to their growth:

• Adequately protecting your eyes form excessive UV light with proper sunglasses
• Protect your eyes in dry, dusty conditions
• Apply artificial tears to your eyes when dry
