An inflammation of the nasolacrimal sac caused by obstruction or infection is known as:

• A. conjunctivitis
• B. a coloboma
• C. dacryocystitis
• D. leukocoria

Answer: (C)

Dacryocystitis refers to the inflammation of the nasolacrimal sac, which can occur as a result of obstruction or infection. The nasolacrimal sac plays a vital role in draining tears from the eye into the nasal cavity. When this drainage system is blocked, tears cannot properly exit, leading to a buildup of fluids that can become infected, resulting in inflammation (dacryocystitis). This condition is often characterized by symptoms such as swelling, redness, and tenderness at the inner corner of the eye near the nose, along with possible discharge. Effective treatment typically involves addressing the underlying cause of the obstruction and managing any infections that may have arisen. In contrast, conditions like conjunctivitis refer to inflammation of the conjunctiva, a different part of the eye, while a coloboma is a congenital defect resulting in incomplete closure of the eye structures, and leukocoria refers to an abnormal white reflection from the retina, which can signal serious underlying conditions. These distinctions underscore why dacryocystitis is specifically associated with the nasolacrimal sac and its associated symptoms and causes.
