Scratch or trauma to the cornea is called what?

• A. Corneal Abrasion
• B. Keratitis
• C. Stye
• D. Astigmatism

Answer: (A)

Corneal abrasion A corneal abrasion is a scratch or trauma to the cornea, the clear front surface of the eye. When the outer epithelial layer is scraped or injured, you typically feel sharp eye pain, tearing, and sensitivity to light, and a fluorescein stain may reveal the scratched area under blue light. Healing is usually quick with proper care to prevent infection, such as avoiding rubbing the eye and using any prescribed antibiotic drops. The other terms describe different problems: keratitis is inflammation or infection of the cornea; a stye is an eyelid gland infection; astigmatism is a refractive error caused by an uneven corneal shape.
