Which of the following is NOT a physical sign of acute dacryoadenitis?

Acute dacryoadenitis is an inflammation of the lacrimal gland, typically presenting with several distinct physical signs. The key features of this condition include swelling of the lateral third of the upper lid, which is due to the enlargement of the lacrimal gland, and often chemosis, which is the swelling of the conjunctiva. Mucopurulent discharge may also be observed in cases of secondary bacterial infections.

Chronic dryness of the eyes, however, is not a physical sign of acute dacryoadenitis. It is more often associated with chronic conditions such as Sjögren's syndrome or other forms of dry eye syndromes. In the context of acute dacryoadenitis, the presentation is characterized by inflammation and infection rather than a chronic lack of moisture.

Recognizing the signs and symptoms associated with specific conditions is crucial for accurate diagnosis and treatment. Understanding the distinctions helps in understanding the underlying pathophysiology and the clinical approach to various eye disorders.
