Beating Pterygium: Insights from an Optometrist.

As optometrists, we are often faced with patients who complain of red, irritated eyes and a growth on the white of their eye. This growth is called a pterygium, and it is a relatively common condition that can cause a range of symptoms and visual disturbances. In this blog, we will discuss what pterygium is, its causes, and the available treatments for this condition.

What is a Pterygium?

A pterygium is a triangular shaped growth that starts on the white part of the eye (sclera) and grows towards the cornea. It is made up of fibrous tissue and can be pink or red in color. Pterygium is often referred to as "surfer's eye" as it is commonly seen in people who spend a lot of time outdoors, especially in bright and sunny environments.

Causes of Pterygium

The exact cause of pterygium is unknown, however, several factors are believed to contribute to its development. These include:

Sun exposure: People who spend a lot of time outdoors, especially in bright and sunny environments, are at a higher risk of developing pterygium.

Dry Eye: People with dry eye syndrome are also more susceptible to developing pterygium.

Dust and Wind: Exposure to dust and wind can also cause irritation and inflammation, leading to the growth of pterygium.

Symptoms of Pterygium

The symptoms of pterygium can vary from person to person. Some common symptoms include:

Irritation: The pterygium can cause itching, burning, and soreness in the eye.

Redness: The growth can cause redness and swelling of the eye.

Blurring: The pterygium can obstruct the vision and cause blurring, especially when it grows towards the cornea.

Discomfort: People with pterygium may experience discomfort and a feeling of foreign body in the eye.

Diagnosis and Treatment of Pterygium

Pterygium is usually diagnosed during a comprehensive eye exam by an optometrist. During the exam, the optometrist will examine the eye, including the cornea and sclera, to look for any signs of pterygium.

Treatment for pterygium depends on the severity of the symptoms and the size of the growth. In some cases, no treatment may be necessary if the pterygium is small and not causing any symptoms. However, if the pterygium is causing discomfort or visual disturbances, there are several treatments available,

including:

Artificial tears: For people with mild symptoms, the use of artificial tears can provide relief and prevent further growth.

Steroid eye drops: For more severe cases, the optometrist may prescribe steroid eye drops to reduce inflammation and redness.

Surgery: In severe cases, surgical removal of the pterygium may be necessary. This is a minor surgical procedure that can be performed by an eye specialist.

Conclusion

In conclusion, pterygium is a common condition that affects the eye and can cause a range of symptoms. If you are experiencing any symptoms of pterygium, it is important to seek the advice of an optometrist for an accurate diagnosis and appropriate treatment. With proper care and treatment, pterygium can be managed effectively and prevent it from affecting your vision.
