What Is Pterygium of the Eye?

Pterygium of the eye is a condition that thickens the outer layer of the eye. It causes redness, irritation and sometimes blocked vision. Pterygium will grow into the clear covering that protects and shields the eyes from dust and other particles. Those who spend a great deal of time out in the environment are most likely to develop pterygium.

Formation

• The cornea is a transparent covering of the eye ball, iris and other parts of the organ. A thick callus forms as a result of constant irritation. If the thickness enlarges and blocks vision, blindness might be experienced until the callus is removed.

Causes of Pterygium

• The main causes of this condition are dust and dry environments. Those who love to hike or spend time in dusty conditions may need to wear protective eye gear to help prevent these things from entering their delicate eyes. Sunlight is also a cause that affects the eye's condition. It is advised that people use eyewear with a high UV ray protector. The gear should completely cover the eye area and leave no gaps between the frame and face.


• The last cause is a condition called dry eyes. The cornea can become dry or irritated if it lacks the proper amount of moisture. Those who work long hours or endure eye strain may be affected by pterygium.

Treatments

• Pterygium of the eye is usually treated with ointments or eye drops. These things can add moisture and treat the condition safely. If these medications do not work after a certain amount of time, surgery can be an option. Surgery removes the growth and helps reduce the chances of it reoccurring.

Past Treatments

• Past surgical eye treatments were not as effective as the methods used today. Half of the patients would experience a re-growth of the condition. Now, surgeons are using transplant procedures called autographs to replace the removed tissue. This prevents re-growth and increases the success of healing.
