Final answer:
Dacroadenitis is the inflammation of the lacrimal gland, while dacrocystitis is the inflammation of the lacrimal sac. Their symptoms and treatment options vary.
Step-by-step explanation:
Dacroadenitis is the inflammation of the lacrimal gland, whereas dacrocystitis is the inflammation of the lacrimal sac often associated with a plugged nasolacrimal duct. These terms refer to different parts of the lacrimal system in the eye.
Dacroadenitis involves the inflammation of the lacrimal gland, which produces tears. It can cause pain, swelling, and tenderness in the upper outer corner of the eye. On the other hand, dacrocystitis is characterized by swelling, redness, and discharge from the inner corner of the eye due to a blockage in the tear drainage system.
While dacroadenitis is less common, dacrocystitis is relatively more prevalent, especially among infants and older individuals. Both conditions can be treated with medical interventions such as antibiotics, warm compresses, and, in severe cases, surgical intervention.
