    Summary
    This summary is machine-generated.

    Lacrimal sac stones, found in 16% of patients, can be associated with fungal infections. Canalicular dacryoliths, however, are linked to anaerobic bacteria. Stone recognition and removal are key treatments for both conditions.

    Area of Science:

    • Ophthalmology
    • Pathology
    • Microbiology

    Background:

    • Chronic dacryocystitis and dacryostenosis can be associated with the formation of stones within the lacrimal drainage system.
    • The etiology and microbial profile of lacrimal sac stones and canalicular dacryoliths require further investigation.

    Purpose of the Study:

    • To investigate the incidence, histopathology, and microbiology of lacrimal sac stones.
    • To analyze the clinical and bacteriological findings in patients with canalicular dacryoliths.

    Main Methods:

    • Retrospective analysis of 70 patients undergoing dacryocystorhinostomy for lacrimal sac stones.
    • Histopathological examination and culture of lacrimal sac stones.
    • Clinical and bacteriological evaluation of 9 patients with canalicular dacryoliths.

    Main Results:

    • Lacrimal sac stones were identified in 16% of patients undergoing dacryocystorhinostomy.
    • Six lacrimal sac stones showed fungal morphology; cultures revealed aerobes and fungi.
    • Canalicular dacryoliths were associated with anaerobic bacteria, including Arachnia propionica and Fusobacterium species, with no fungal presence.

    Conclusions:

    • Fungal infections may be implicated in the formation of lacrimal sac stones.
    • Anaerobic bacteria are predominant in canalicular dacryoliths.
    • Prompt recognition and surgical removal of lacrimal stones are crucial for effective management.
