Idiopathic Dacryoadenitis: Clinical Features, Histopathology, and Treatment Outcomes

Area of Science:

• Ophthalmology
• Pathology

Background:

• Idiopathic dacryoadenitis is an inflammatory condition affecting the lacrimal gland.
• Understanding its clinical and histologic features is crucial for effective management.
• Prognostic factors for treatment outcomes require further elucidation.

Purpose of the Study:

• To review the clinical and histologic features of idiopathic dacryoadenitis.
• To identify prognostic factors for disease recurrence, treatment recalcitrance, and incomplete response.

Main Methods:

• Retrospective interventional case series at tertiary referral centers.
• Analysis of 79 biopsy-confirmed idiopathic dacryoadenitis cases.
• Review of patient demographics, clinical presentation, histopathology, and treatment outcomes.

Main Results:

• Mean patient age was 50 years, with 57% female and 16% bilateral cases.
• 20% of cases were recalcitrant, 17% had incomplete response, and 15% recurred over 64 months.
• Male sex and extraocular muscle inflammation predicted incomplete response; classic presentation predicted recalcitrance; bilateral cases had higher recurrence risk.

Conclusions:

• A significant proportion of idiopathic dacryoadenitis cases exhibit poor treatment response or recurrence.
• Identified prognostic factors, including sex, laterality, and clinical presentation, may guide management strategies.
• These novel prognostic factors offer insights for predicting outcomes in idiopathic dacryoadenitis.
