Dacryoadenitis means inflammation of the lacrimal gland. “Dacryo-” refers to tears, and “-adenitis” means gland inflammation. So it literally means the tear gland is inflamed. This inflammation can cause the gland to swell, become tender, and affect tear production. The condition may affect one eye (unilateral) or both eyes (bilateral), and it may come on quickly (acute) or slowly over weeks to months (chronic). NCBIMedlinePlusMedscapeCleveland Clinic
Dacryoadenitis is swelling and inflammation of the lacrimal gland, the small tear-making gland located in the upper outer corner of the eyelid near each eye. This gland makes the watery part of your tears. When it becomes inflamed, it can hurt, swell, and sometimes cause redness, excessive tearing, or a change in the shape of the eyelid (often an “S”-shaped droop). The condition can come on suddenly (acute) or last a long time (chronic). Acute dacryoadenitis is most often caused by infections like viruses (e.g., mumps, Epstein-Barr, adenovirus) or bacteria (e.g., staphylococcus, gonococcus), while chronic cases tend to be due to immune-related inflammation such as from autoimmune diseases (sarcoidosis, thyroid eye disease, or IgG4-related disease). Prompt identification and appropriate treatment help prevent complications. NCBI MedlinePlus All About Vision
Types of Dacryoadenitis
Dacryoadenitis is classified based on duration and cause. The major types are:
A. Acute Dacryoadenitis
This comes on suddenly, usually over hours to a few days. It often causes pain, redness, and a noticeable swollen bump in the outer upper eyelid. Most commonly it is due to infection, especially viruses or bacteria. MedscapeMedlinePlusDoveMed
B. Chronic Dacryoadenitis
This develops slowly, over weeks to months, and usually causes less pain but persistent swelling. It is most often caused by non-infectious inflammatory diseases like autoimmune conditions. The swelling may be firm and often affects both sides. ResearchGateMedscapeEnto Key
C. Infectious vs Non-Infectious
Infectious dacryoadenitis is caused by germs: viruses (e.g., mumps, Epstein-Barr), bacteria (e.g., Staphylococcus), or rarely fungi. MedlinePlusPubMed CentralDoveMed
Non-infectious dacryoadenitis is caused by immune system activity, such as sarcoidosis, Sjögren’s syndrome, Graves’ disease, or IgG4-related disease. These do not involve direct invasion by germs but an abnormal immune reaction. ResearchGateKJR OnlineMedscape
D. Granulomatous / Specific Subtypes
Some cases are granulomatous, meaning the immune system forms small organized clusters of cells in the gland, as seen in sarcoidosis or IgG4-related disease. Distinguishing these from other causes is important because treatment and follow-up differ. KJR OnlineEnto Key
E. Idiopathic / Nonspecific
When careful testing does not find a clear cause, it is called idiopathic or nonspecific dacryoadenitis. This is a diagnosis made after ruling out infections, autoimmune diseases, and lymphoma. KJR Online
Main Causes of Dacryoadenitis
Each of the following is a common or important cause. They are grouped loosely but described individually.
Mumps virus – A viral infection that classically causes swelling of salivary glands; it can also inflame the lacrimal gland, leading to acute painful swelling. MedlinePlus
Epstein-Barr virus (EBV) – The virus that causes mononucleosis can lead to acute dacryoadenitis, sometimes as an early or isolated sign. PubMed Central
Herpes simplex and herpes zoster – These herpes family viruses can infect nearby tissues and cause inflammation of the lacrimal gland, often with pain and vesicular skin changes. ScienceDirectReview of Ophthalmology
Influenza and other respiratory viruses – Seasonal viral infections can spread to the lacrimal gland, causing acute inflammation. JournalAgent

Chronic fungal infections – Especially in immunocompromised people, fungi can infect orbit tissues and cause lacrimal gland inflammation. DoveMed
Idiopathic nonspecific inflammation – When no infectious or systemic autoimmune cause is found, the gland may be inflamed for unclear reasons; diagnosis is by excluding others. KJR Online
Common Symptoms
Dacryoadenitis symptoms depend on cause and acuity, but these are the most frequent:
Swelling in upper outer eyelid – The lacrimal gland is just under this area, so inflammation causes a visible bump or fullness, often giving the eyelid an S-shaped curve. NCBIMedscape
Pain or discomfort – Especially in acute infectious cases, the area over the gland feels sore or tender. Review of OphthalmologyMedscape
Redness of eyelid and surrounding skin – The inflamed tissue becomes flushed due to increased blood flow. Medscape
Tearing or watery eye – The gland may be irritated or dysfunctional, causing abnormal tear production or reflex tearing. Review of Ophthalmology
Purulent or mucous discharge – Especially in bacterial infections, the eye may ooze pus or thick mucus. Medscape
Fever or general malaise – Seen in infectious causes, where the body shows systemic signs like fever, tiredness, or feeling unwell. MedlinePlus
Eyelid droop (ptosis) – Swelling of the gland can weigh the eyelid down or distort its shape. EyeWiki
Conjunctival injection (red eye) – Blood vessels in the white part of the eye may become more visible due to nearby inflammation. Medscape
Chemosis (conjunctival swelling) – Fluid can collect in the conjunctiva, making it look puffy. Medscape
Limited eye movement – If inflammation extends, it can slightly limit how the eye moves, causing discomfort with gaze. EyeWiki
Regional lymph node enlargement – Nearby lymph nodes, like submandibular nodes, may swell in response to infection. Medscape
Dry eye symptoms – In chronic immune-mediated cases, tear production may decrease, producing feeling of grit or dryness. Review of Ophthalmology
Double vision – Rare, but if the inflammation affects the position or movement of the eye, patients may see double. EyeWiki
Palpable firmness in the gland region – On touch, the gland may feel firm or slightly hard in chronic inflammation. Medscape
Unexplained bilateral swelling – When both sides are involved, especially in autoimmune or systemic disease, swelling may be present in both upper lids. ResearchGateJohns Hopkins Medicine
Main Diagnostic Tests
Diagnosis combines what the doctor sees and feels with targeted tests to find the cause. The tests are grouped below.
A. Physical Exam
Inspection of eyelid and orbit – The doctor looks at the outer upper eyelid for swelling, redness, and the classic S-shaped curve that comes from an enlarged lacrimal gland. Medscape
Palpation with eyelid eversion – Gently feeling the lacrimal gland through the upper eyelid (often by everting the eyelid) assesses tenderness, size, and consistency. This distinguishes acute painful from chronic firm enlargement. Medscape
Assessment of ocular motility and globe position – Checking eye movements can reveal if inflammation is pushing on nearby muscles or tissues, causing limited movement or slight displacement (proptosis). EyeWiki
Regional lymph node exam and systemic signs – Feeling for nearby lymph node swelling (e.g., submandibular) and looking for systemic features like fever or signs of autoimmune disease helps narrow the cause. Medscape
B. Manual / Functional Tests
Schirmer’s test – Measures tear production by placing a small strip of paper under the lower eyelid. It helps assess if glands are producing tears normally, useful especially when dryness or Sjögren’s is suspected. Johns Hopkins Medicine
Fluorescein staining – A dye placed in the eye shows damage to the surface (cornea) and tear film problems; helps see if inflammation has affected the ocular surface. Review of Ophthalmology
Tear break-up time (TBUT) – Measures how long the tear film stays stable; helps identify functional tear problems that may accompany chronic inflammatory causes. Review of Ophthalmology
C. Laboratory and Pathological Tests
Complete blood count (CBC) with differential and inflammatory markers (ESR/CRP) – Elevated white blood cells, ESR, or CRP suggest infection or systemic inflammation. Medscape
Bacterial culture and Gram stain of any discharge – If pus or secretion is present, identifying bacteria guides antibiotic choice. MedscapeMedlinePlus
Viral PCR/serology (e.g., EBV, mumps, herpes) – Tests to detect specific viral causes, especially in acute painful swelling without obvious bacterial infection. PubMed CentralMedlinePlus
Autoimmune panel (ANA, rheumatoid factor) – Screens for systemic autoimmune diseases like lupus or rheumatoid conditions that can cause chronic dacryoadenitis. Medscape
IgG4 serum level – Elevated in IgG4-related disease, a key cause of chronic, often bilateral gland enlargement. KJR Online
Angiotensin-converting enzyme (ACE) level and chest imaging correlation – Used when sarcoidosis is suspected; ACE may be elevated and chest findings help support diagnosis. Ento Key
Thyroid function tests – To evaluate Graves’ disease or other thyroid-related orbital inflammation. Medscape
Biopsy of lacrimal gland with histopathology (and flow cytometry if needed) – Removing a small tissue sample is the gold standard when chronic, unexplained, or suspecting lymphoma; pathology can reveal granulomas, malignancy, or IgG4-related changes. MedscapeKJR Online
D. Electrodiagnostic / Nerve-Related Tests
Facial nerve function testing / EMG if eyelid movement is abnormal – Though not routine for dacryoadenitis itself, if eyelid droop or weakness raises concern for nerve involvement, electromyography (EMG) or clinical nerve testing helps rule out nerve palsy mimics. EyeWiki
Sensory testing of trigeminal nerve and lacrimal reflex assessment – Assessing sensation around the eye and reflex tearing helps exclude neural causes or referred pain that could confuse the diagnosis. (Note: there is no standard “lacrimal gland electrodiagnostic” test; these are used in difficult differential diagnoses.) Review of Ophthalmology
E. Imaging Tests
Magnetic resonance imaging (MRI) of the orbit with contrast – Provides detailed soft tissue images to see enlargement of the lacrimal gland, differentiates inflammation versus tumor, and evaluates extent and involvement of adjacent structures. KJR Online
Computed tomography (CT) scan of the orbits with contrast – Shows bone and soft tissue, helps identify gland enlargement, abscess formation, or secondary orbital involvement. Useful in acute cases or when mass is suspected. Ento KeyEnto Key
Orbital ultrasound – Quick bedside test to assess size, internal structure, and vascularity of the lacrimal gland; helps distinguish solid from cystic or vascular lesions. DoveMed

Frequently Asked Questions
What exactly causes dacryoadenitis?
It is caused by infection (viral or bacterial) in acute cases, or by immune system conditions like sarcoidosis or thyroid disease in chronic cases. MedlinePlusIs dacryoadenitis contagious?
If caused by a virus or bacteria (like mumps or staph), the underlying infection can spread, so hygiene is important. MedlinePlusHow long does acute dacryoadenitis last?
Viral forms often improve in about a month with supportive care; bacterial types improve with appropriate antibiotics over days to weeks. Cleveland ClinicMedscapeCan dacryoadenitis damage vision?
Rarely, unless the inflammation spreads deeper into the orbit causing pressure effects; prompt treatment usually prevents this. MedscapeWhat is the difference between dacryoadenitis and dacryocystitis?
Dacryoadenitis affects the tear-producing gland (upper outer eyelid); dacryocystitis affects the tear drainage sac near the nose. Cleveland ClinicAre home treatments enough?
Mild viral cases may improve with warm compresses and rest, but worsening, fever, or bacterial suspicion needs a doctor. MedscapeWhen is surgery needed?
If there is a suspicious chronic mass (biopsy), abscess needing drainage, or nonresponsive chronic inflammation causing disfigurement. EyeWikiMedscapeCan it come back?
Yes, especially if underlying autoimmune disease is not controlled. Chronic or recurrent cases should prompt evaluation for systemic illness. EyeWikiShould I avoid contact lenses?
Yes, during active inflammation to prevent further irritation and infection. All About VisionAre supplements helpful?
Some like omega-3s and vitamin D can help reduce inflammation and support the tear system, especially if dry eye features coexist. PubMed CentralScienceDirectHow is chronic dacryoadenitis diagnosed?
Clinical exam, imaging if needed (CT/MRI), and sometimes a biopsy to rule out tumors or define autoimmune cause. EyeWikiCan antibiotics hurt if the cause is viral?
Unnecessary antibiotics provide no benefit and risk side effects; doctors try to distinguish cause before giving them. MedscapeIs prednisone safe for chronic cases?
It’s effective but has side effects; doctors usually taper dose and may add steroid-sparing drugs like methotrexate. NCBIEyeWikiWhat tests will my doctor order?
Blood tests for underlying autoimmune markers, imaging to look at gland structure, cultures if infection suspected, or biopsy for chronic unexplained swelling. EyeWikiMedscapeCan lifestyle changes help?
Yes. Staying hydrated, eating anti-inflammatory foods, avoiding smoking, managing stress, and good eyelid hygiene all support recovery and prevention. PubMed CentralAjo
