PTERYGIUM

INTRODUCTION :

    A pterygium is a triangle shaped tissue that grows on the surface of the cornea. It starts at the inner corner of the eye and grows toward the center. Some grow slowly throughout a person’s life, while others may eventually stop. In extreme cases, it can affect vision by covering the pupil of the eye.

PTERYGIUM TREATMENT

1. DROPS

    If the pterygium is causing a lot of irritation or redness, your doctor may prescribe eye drops or eye ointments that contain corticosteroids to reduce inflammation.

    Short-term use of topical corticosteroid eye drops may be used to reduce redness and inflammation. Where dryness of the eye is a problem, artificial tears are used to keep the eye well lubricated.

    After applying one drop wait for 5 minutes before putting the next drop.

WHEN TO DO SURGERY:

    A pterygium can be removed by surgery. However, this is only recommended if the growth affects vision. The pterygium may affect vision if it covers the pupil or by exposure to in early stage smoke or dust.

    A pterygium can be removed for cosmetic reasons. This is not advised because it often grows back. To make it less noticeable, doctors may instead advise eye drops. These reduce irritation and redness.

SURGERY :

    Surgery may be recommended if vision is affected or symptoms are particularly problematic.

    During surgery, the pterygium is carefully removed and a section of the conjunctiva is taken from under the eyelid and is grafted onto the area where the pterygium was. Surgery is performed using a local anaesthetic and takes approximately 30 minutes to perform.

 PRECAUTIONS FOR EARLY PTERYGIUM :

•  Use UV protective glasses in sunlight.

•  Use UV protective glasses or helmet with visor while driving.

•  Close your eyes and take shower while bathing.

•  Avoid dust, heat & wind.
