She had no history of epiphora, and her lacrimal drainage system was patent on irrigation. Introduction: The aim of this study was to clarify the effectiveness of various imaging modalities and characteristic imaging features in the screening of IgG4-related dacryoadenitis and sialadenitis (IgG4-DS), and to show the differences in the imaging features between IgG4-DS and Sjögren's syndrome (SS). Dacryocystitis, inflammation of the nasolacrimal system, is frequently encountered in rabbits and can be a frustrating condition to manage. Since the aetiology and prognosis are different from dogs (and cats) the condition is being discussed separately. Most rabbits present with unilateral disease but on occasion it can be bilateral.

Acute dacryocystitis is treated systemically, whereas chronic dacryocystitis may require dacryocystorhinostomy (DCR) . An acquired dacryocystocele is a diffuse and centrifugal enlargement of the lacrimal sac that forms as a result of obstruction of lacrimal drainage system proximally at the level of the common canaliculus and distally at the level of nasolacrimal duct [ 1 Dacryocystitis is an infection or inflammation of the nasolacrimal sac, usually accompanied by blockage of the nasolacrimal duct. Dacryocystitis can be acute or chronic and congenital or acquired.

1 The eyelids are critical to ocular Dacryocystitis is a bacterial infection of the lacrimal sac. Although uncommon, dacryocystitis can occur at any age as a bacterial complication of a viral upper respiratory tract infection (URI). Because of the course traversed by the lacrimal duct, which drains to the inferior meatus within the nose, it is surprising that the duct and sac are not infected more often. Dermoid cyst simulating recurrent dacryocystitis in a toddler.

Imaging also may be used to assess possible complications of orbital cellulitis or abscess. A DCR procedure involves removal of bone adjacent to the nasolacrimal sac and incorporating the lacrimal sac with the lateral nasal mucosa in order to bypass the nasolacrimal duct obstruction. This allows tears to drain directly into the nasal cavity from the canaliculi via a new low-resistance pathway. Dacryocystitis is relatively common in the general population, with the majority of cases presenting during the first or fifth decade of life. 4,5 Infantile or congenital dacryocystitis occurs in 3% to 6% of infants, due to either epithelial debris blocking the duct or incomplete development of the lacrimal canal. 5 Dacryocystitis secondary to nasolacrimal duct obstruction is more common in older individuals as a result of mucosal degeneration, ductile stenosis and tear stagnation.

Dacryocystitis can be acute or chronic and congenital or acquired. Dacryocystitis is caused by a blocked tear duct. Tears become trapped in the sac and form a pool. Bacteria can then begin to grow in the tear pool and create an infection.

There is often mucopurulent discharge from the puncta and associated conjunctivitis. Dacryocystitis is the inflammation/ infection of the lacrimal sac from an obstruction.
