What is Corneal Scar?
Corneal Scar is also known as pink eye.
The cornea is an integral part of the eye. It is your eye’s clear, protective outer layer. It helps the eye to focus properly and causes the involuntary reflex for the eyelids to close. Along with the sclera (the white portion of your eye), cornea serves as a barrier against dirt, germs, and other things that can cause damage.
It also plays a key role in vision. As light enters your eye, it gets refracted, by the cornea’s curved edge. This helps determine how well your eye can focus on objects near and far away. If your cornea is damaged by any kind of disease, infection, or injury, the resulting scars can affect your vision. They might block or distort light when it enters your eye.
Causes of Corneal Scar
Corneal scars may be caused by the following:
- Injury to the cornea (abrasion, laceration, burns, or disease).
- Most cases of corneal ulcers are due to a bacterial infection that invades the cornea — often following eye injury, trauma or other damage.
- Another major cause of corneal ulcer is herpes simplex virus infection, which can damage the exterior and sometimes even deeper layers of the eye's surface.
- Genetics – One may inherit this disease from the parents.
- Chemical burns or other caustic (damaging) solution splashes can injure the cornea and lead to corneal ulceration.
- Allergies also affect your eyes and cause corneal scars. Typically eye allergies are triggered by one of the following:
- Indoor allergens like dust and dander
- Outdoor allergens like pollens
- Irritants like smoke and perfume

He or she may use magnifying tools, such as a slit lamp or ophthalmoscope, to get a better view of your eye. Your doctor may also use a painless process called a fluorescein eye stain, in which dyed eye drops and blue light are used to visualize your cornea in a better way.
