What condition involves inflammation of the eyes and can result from an allergic reaction?

• A. Conjunctivitis
• B. Blepharitis
• C. Myopia
• D. Uveitis

Answer: (A)

Conjunctivitis, commonly known as pink eye, is indeed the condition that involves inflammation of the conjunctiva, which is the membrane covering the white part of the eye and the inner eyelids. This inflammation can arise from various causes, including allergic reactions to substances such as pollen, animal dander, or dust mites. When the eyes are exposed to allergens, the immune system responds by releasing histamines, leading to redness, itching, and tearing, which are characteristic symptoms of allergic conjunctivitis. In contrast, blepharitis primarily affects the eyelids and involves inflammation of the eyelid margins due to seborrheic dermatitis or bacterial infections, not necessarily caused by allergens. Myopia, or nearsightedness, is a refractive error related to the shape of the eye, and therefore does not involve inflammation. Uveitis refers to inflammation of the uvea, which is deeper within the eye structure, and while it can have various causes, it is not specifically linked to allergic reactions in the same manner that conjunctivitis can be. Thus, conjunctivitis is the clear choice for a condition that specifically involves eye inflammation due to allergic responses.
