Answer :
A pterygium is a growth of tissue on the conjunctiva (the clear tissue that covers the white part of the eye) that can extend onto the cornea. It is often associated with excessive exposure to ultraviolet (UV) light, such as from the sun.
Treatment for a pterygium may vary depending on the severity of the condition. Here are some common treatment options:
1. **Conservative Management**: In mild cases, where the pterygium is not causing significant symptoms or vision problems, the doctor may recommend using artificial tears to keep the eye lubricated and reduce irritation.
2. **Surgical Removal**: If the pterygium is causing discomfort, redness, vision disturbances, or is cosmetically bothersome, surgical removal may be necessary. During the procedure, the growth is excised, and sometimes a graft from another part of the eye is used to cover the area where the pterygium was removed.
3. **Preventative Measures**: To prevent pterygium formation or recurrence after surgery, individuals are advised to protect their eyes from excessive UV exposure by wearing sunglasses that block UVA and UVB rays, along with a wide-brimmed hat.
Regular eye exams are important to monitor the growth of a pterygium and to determine the most appropriate course of action for treatment. If you suspect you have a pterygium or are experiencing eye discomfort, it is essential to consult an eye care professional for proper evaluation and management.
