PTERYGIUM



Aunty doc well done oo!!! Please I want to complain to you about my eye.
See eehh, just look at my eye there's something growing there and it's moving towards my black eye. This thing disturbs me alot especially when I'm outside, on a bike, when it's airy, or when I'm cooking with my firewood, sometimes when I stay under the air condition for a long time.
You know the worst part of it is that it makes me feel like there's sand in my eyes, it itches me, and sometimes my eyes turn red and pains me.
Doc abeg what is this?

Madam this growth on your eye is called PTERYGIUM!!!

•WHAT IS PTERYGIUM?
A pterygium also called "surfer's eye" is a visible, often triangular, growth on the surface of the eye. It is an elevated, wedged-shaped bump on the eyeball that starts on the white of the eye (sclera) and can invade the cornea.
Pterygium is a benign (non-cancerous) growth, but, if left untreated, can extend across the pupil obscuring vision, and it can also disfigure the eye. They also can cause discomfort and blurry vision. It may occur on one or both eyes. It's more common in people who spend a lot of time in the sun, such as those who work outdoors.
💖
• CAUSES OF PTERYGIUM
√ Exposure to excessive amounts of ultra-violet light is thought to be the most significant cause of pterygia, which are more common in people living in sunny areas and in people whose jobs expose them to ultra-violet light (eg: farmers, arc welders).
√ Environmental irritants (eg: wind, dust, chemicals, air pollution).
√ Hereditary factors.

• SYMPTOMS
Sometimes, there are none -- it just shows up.
The following occurs when there are symptoms:

- Burning Sensation
- Gritty Sensation
- Itching
- Feeling like you have something in it
- Redness
 - Dry eye due to reduced tear production
💖
• DIAGNOSIS OF PTERYGIUM
Diagnosing a pterygium is straightforward. Your eye doctor may diagnose this condition based on a physical examination using a slit lamp. ... If your doctor needs to do additional tests, they may include: Visual acuity test.
💖
• TREATMENT OF PTERYGIUM
Treatment depends on the size and nature of the pterygium, the symptoms and whether vision is affected. There are two main ways a pterygium can be treated;
1. Short term use of topical corticosteroid eye drops may be used to reduce redness and inflammation.
2. Surgery to remove the growth if it grows to the extent of obstructing vision.
💖
NOTE:. a. PTERYGIUM can reoccur even after surgery.
             b. PTERYGIUM occur twice as frequently in males than females and are most common in people older than 40 years of age.
💖
• CAN PTERYGIUM GROW BACK AFTER SURGERY?
Unfortunately a pterygium will often grow back after surgery to remove it. (This may be more likely if you are under age 40.) Sometimes the growth that comes back causes worse symptoms than the original one.
💖
• CAN PTERYGIUM MAKE YOU BLIND?
In extreme cases, it can cover your pupil and cause vision problems.
💖
HOW CAN YOU PREVENT PTERYGIUM?
You can help prevent the development of a pterygium by wearing sunglasses or a hat to shield your eyes from sunlight, wind, and dust. Your sunglasses should also provide protection from the sun's ultraviolet (UV) rays. If you already have a pterygium, limiting your exposure to the following can slow its growth.
