Orbital Cellulitis Secondary to Dacryocystitis: A Case Series and Literature Review.
Ophthalmic Plast Reconstr Surg
December 2024
Orbital, Plastics and Lacrimal Unit, Royal Victorian Eye and Ear Hospital, East Melbourne, Victoria, Australia.
Article Synopsis
- This study focused on identifying risk factors and management outcomes for patients with orbital cellulitis stemming from dacryocystitis, analyzing a group of 18 patients.
- The majority of patients (56% female, mean age 62) experienced reduced visual acuity, but most showed improvement after treatment, with acute intervention helping in resolving acute cellulitis.
- Key findings suggested that recurrent dacryocystitis and the presence of dacryoliths are significant risk factors, while immunosuppression worsens prognosis; successful long-term resolution typically requires dacryocystorhinostomy.

In addition to being a drainage system, the lacrimal ducts actively defend the eye through the action of the lacrimal pump, the presence of resident flora (lacriome) and the mucosa-associated immune tissue. Infection occurs when mucosal immune functions are overwhelmed. Lacrimal infection is a vicious circle, in which infection leads to inflammation and post-inflammatory sequelae, themselves a source of occlusion and stagnation, which in turn encourages infection.

Dacryocystitis in a Patent Nasolacrimal Drainage System: A Literature Review.

Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Saudi Arabia.
Introduction: Acute dacryocystitis is an acute infection and the lacrimal sac secondary to pathogenic microorganism growth within the stagnant fluid in the lacrimal sac secondary to nasolacrimal duct obstruction.
Methods: A literature review was conducted on the PubMed database using the following search terms "dacryocystic retention" and "dacryocystitis" or "dacryolith" or "lacrimal duct" or "pseudo-dacryocystitis".
Results: The literature review suggests that dacryocystitis in a patent nasolacrimal drainage system can stem from diverse causes including the mechanical impaction by dacryoliths, viral infections and anatomical variations.
Key Clinical Message: Asymptomatic lacrimal canaliculus stones causing many stones without symptoms are rare. The patient recovered well within a week after dacryolith removal. This diagnosis is prevalent in this age group.
