What term refers to redness of the cornea?

• A. Corneal injection
• B. Diplopia
• C. Raccoon eyes
• D. Cerumen impaction

Answer: (A)

The term that refers to redness of the cornea is indeed corneal injection. This condition is often characterized by the dilation of blood vessels in the conjunctiva and the cornea, which can lead to a noticeable reddening of the eye. This phenomenon can occur due to various reasons, such as inflammation, irritation, or infection, and is an important clinical sign that can help healthcare providers assess the health of the eye.

In contrast, the other terms listed refer to different medical concepts. Diplopia refers to double vision, which is a visual disturbance rather than a physical change to the cornea. Raccoon eyes describe a specific pattern of bruising around the eyes often associated with skull fractures, not a condition affecting the cornea. Cerumen impaction refers to a blockage of the ear canal due to earwax buildup and is unrelated to eye health. Understanding the specific context of these terms is crucial for accurate communication in the medical field.
