Introduction
Background
The lacrimal gland is located in the supratemporal orbit. Two lobes exist, the orbital and the palpebral. The palpebral lobe is visualized easily by upper lid eversion. This eccrine secretory gland is responsible for the formation of the aqueous layer of the tear film.
By definition, dacryoadenitis is an inflammatory enlargement of the lacrimal gland. Dacryoadenitis may be separated into acute and chronic syndromes with infectious or systemic etiology.
Pathophysiology
The pathophysiology is not understood completely. Yet, infectious dacryoadenitis is thought to be caused by ascension of an inciting agent from the conjunctiva through the lacrimal ductules into the lacrimal gland.
Frequency
United States
Dacryoadenitis is uncommon; therefore, data about its prevalence are sparse. One in 10,000 ophthalmic patients has dacryoadenitis according to one report. Inflammatory enlargement of the lacrimal gland is much more common than lacrimal gland tumors.
Mortality/Morbidity
No data are available. Acute dacryoadenitis tends to be a self-limiting condition. Patients with chronic dacryoadenitis need management of their systemic condition.
Race
No racial predilection is noted.
Sex

Age
No age predilection is noted.
Clinical
History
- Acute dacryoadenitis
- Unilateral, severe pain, redness, and pressure in the supratemporal region of the orbit
- Rapid onset (hours to days)
- Chronic dacryoadenitis
- Can be bilateral, painless enlargement of the lacrimal gland present for more than a month
- More common than acute dacryoadenitis
Physical
- Acute dacryoadenitis
- The palpebral lobe of the lacrimal gland is often involved and is easily seen by everting the upper lid. It is noted to be prolapsed and enlarged. The palpebral lobe tends to be firm and tender upon palpation through the lid.
- Other associated ophthalmic physical signs of acute dacryoadenitis include the following:
- Chemosis (conjunctival swelling)
- Conjunctival injection
- Mucopurulent discharge
- Erythema of eyelids
- Lymphadenopathy (submandibular)
- Swelling of the lateral third of the upper lid (S-shaped lid)
- Proptosis
- Ocular motility restriction
- Globe displacement inferiorly and medially
- Increased severity of signs and symptoms with orbital lobe involvement
- Acanthamoeba keratitis associated (rarely)
- Systemic physical signs of acute dacryoadenitis include the following:
- Parotid gland enlargement
- Fever
- Upper respiratory infection
- Malaise
- Chronic dacryoadenitis
- Less severe presentation than acute dacryoadenitis
- No pain (usually)
- Enlarged gland but mobile
- Minimal ocular signs
- Mild ptosis secondary to enlargement of the gland (possible)
- Mild-to-severe dry eyes
Causes
- Infectious
- Viral (most common)
- Mumps (most common, especially in childhood)
- Epstein-Barr virus
- Herpes zoster
- Mononucleosis
- Cytomegalovirus
- Echoviruses
- Coxsackievirus A
- Bacterial
- Fungal (rare)
- Histoplasmosis
- Blastomycosis
- Parasite (rare)
- Schistosoma haematobium
- Protozoa (rare)
- Acanthamoeba keratitis associated
- Viral (most common)
- Inflammatory
- Sarcoidosis
- Graves disease
- Sjögren syndrome3
- Orbital inflammatory syndrome
- Benign lymphoepithelial lesion
