Dacryoadenitis – Causes, Symptoms, Diagnosis, Treatment

Dacryoadenitis refers to acute? or chronic inflammation of the lacrimal gland and can be due to infectious, inflammatory, or idiopathic causes. Acute dacryoadenitis is most common in children and young adults and typically presents with erythema? and tenderness? over the superotemporal orbit with enlargement of the gland causing the lateral portion of the eyelid to fall, creating a characteristic S-shaped curve of the eyelid margin. There can also be associated suppurative discharge from lacrimal ducts, pouting of the lacrimal ductules, conjunctival chemosis, and swelling? of preauricular and cervical? lymph nodes?. Fever? and malaise may be present. Inflammatory causes of dacryoadenitis may present subacutely with typically painless swelling of the lacrimal glands and may be bilateral. Acute lacrimal gland swelling that presents in association with a viral illness does not require a biopsy? or comprehensive laboratory evaluation. However, if there are atypical? features or if the swelling does not resolve with treatment, an additional workup is merited. Occurrence in older adults, bilateral presentation, and systemic? symptoms may suggest a malignant? or systemic autoimmune? process, in which case additional workup is strongly advisable. This activity reviews the presentation, evaluation, and management of dacryoadenitis and stresses the role of an interprofessional team approach to care for affected patients.

Symptoms

The symptoms of dacryoadenitis can vary depending on the underlying cause and the severity of the inflammation. Here is a list of 20 common symptoms associated with dacryoadenitis:

1. Eye pain: Individuals with dacryoadenitis may experience discomfort or aching pain in or around the affected eye.
2. Swelling: The lacrimal gland may become swollen and enlarged, leading to a visible bulge in the upper outer corner of the eye.
3. Redness: The affected eye may appear red or bloodshot due to the inflammation of the lacrimal gland.
4. Tenderness: The lacrimal gland can be tender to touch, causing pain or sensitivity in the area.
5. Watery eyes: Dacryoadenitis can disrupt the normal tear production and drainage process, resulting in excessive tearing or watery eyes.
6. Dry eyes: Paradoxically, some individuals may also experience dryness in the affected eye due to the disruption of tear production.
7. Eye discharge: The inflammation may lead to the production of excessive mucus or pus-like discharge from the affected eye.
8. Eye irritation: The presence of inflammation and excessive tearing can cause irritation, itching, or a gritty sensation in the eye.
9. Blurred vision: In some cases, dacryoadenitis can cause temporary blurred vision due to the disruption of tear film stability.
10. Eye fatigue: Individuals may experience eye fatigue or strain, especially if the inflammation persists for an extended period.
11. Sensitivity to light: The inflamed lacrimal gland can make the affected eye more sensitive to bright light, leading to discomfort or photophobia.
12. Eyelid swelling: In addition to the swelling of the lacrimal gland, the surrounding eyelid may also become swollen or puffy.
13. Eye discharge: Along with excessive tearing, the affected eye may produce a thick, sticky, or yellowish discharge.
14. Eyelid redness: The inflammation may extend to the eyelid, causing redness or a pinkish discoloration.
15. Headache: Some individuals with dacryoadenitis may experience headaches, particularly if the pain radiates from the affected eye.
16. Fever: If the underlying cause of dacryoadenitis is an infection, individuals may develop a fever as a systemic response.
17. Fatigue: The inflammation and associated symptoms can lead to general fatigue or a feeling of tiredness.
18. Swollen lymph nodes: Depending on the cause, the nearby lymph nodes may become enlarged and tender to touch.
19. Limited eye movement: Severe swelling or pain may restrict the movement of the affected eye, causing difficulty in looking around.
20. Systemic symptoms: In some cases, individuals may experience general malaise, loss of appetite, or other systemic symptoms, particularly if the cause of dacryoadenitis is an underlying autoimmune disorder.

It’s important to note that these symptoms can vary in intensity and duration depending on the individual and the underlying cause of dacryoadenitis. If you suspect you may have dacryoadenitis, it’s recommended to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Diagnosis

It can occur due to various causes, including infection, autoimmune disorders, and trauma. The diagnosis of dacryoadenitis involves a combination of clinical evaluation, medical history, and specific tests. Here is a list of 20 common diagnostic procedures and tests used for the diagnosis of dacryoadenitis:

1. Medical history: The first step in diagnosing dacryoadenitis is taking a detailed medical history of the patient, including the onset and duration of symptoms, previous medical conditions, and any relevant family history.
2. Physical examination: A thorough physical examination of the eyes, eyelids, and surrounding structures is performed to assess the signs and symptoms of dacryoadenitis. This may include checking for redness, swelling, and tenderness in the lacrimal gland area.
3. Visual acuity test: This test evaluates the clarity and sharpness of the patient’s vision. It helps determine if the inflammation of the lacrimal gland is affecting vision or not.
4. External eye examination: The external eye examination involves a close inspection of the eyelids, conjunctiva, and surrounding tissues to identify any visible signs of inflammation or infection.
5. Slit-lamp examination: A slit-lamp examination is a specialized microscope that allows a detailed examination of the anterior segment of the eye. It helps in evaluating the lacrimal gland, eyelids, and conjunctiva for signs of inflammation or infection.
6. Fundus examination: A fundus examination is performed to assess the back of the eye, including the retina, optic nerve, and blood vessels. It helps in ruling out other causes of eye symptoms and assessing the overall health of the eye.
7. Blood tests: Blood tests may be ordered to identify the underlying cause of dacryoadenitis. These tests may include a complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and autoimmune markers like antinuclear antibodies (ANA).
8. Microbiological cultures: If infection is suspected, a sample may be taken from the affected area and sent for microbiological culture. This helps identify the specific bacteria or viruses responsible for the infection.
9. Biopsy: In some cases, a biopsy of the lacrimal gland may be necessary to obtain a tissue sample for further analysis. A biopsy can help confirm the diagnosis and rule out other conditions.
10. Imaging studies: Imaging techniques such as ultrasound, magnetic resonance imaging (MRI), or computed tomography (CT) scan may be used to visualize the lacrimal gland and surrounding structures. These tests help identify any structural abnormalities or blockages.
11. Schirmer’s test: Schirmer’s test measures the amount of tears produced by the lacrimal gland. A small strip of filter paper is placed in the lower eyelid, and the amount of wetting is measured after a specific time. A reduced tear production may indicate lacrimal gland dysfunction.
12. Tear osmolarity test: Tear osmolarity test measures the salt content in the tears. Elevated tear osmolarity can be an indicator of lacrimal gland inflammation.
13. Tear film breakup time (TBUT): TBUT test evaluates the stability of the tear film. It involves applying a special dye to the eye’s surface and observing how long it takes for the tear film to break up. A shorter TBUT may indicate inadequate tear production.
14. Schirmer I test: Schirmer I test evaluates the basal tear secretion by placing a filter paper strip in the lower eyelid without anesthesia. The amount of wetting in a specific time indicates the baseline tear production.
15. Meibography: Meibography is a specialized imaging technique that examines the structure of the meibomian glands. These glands play a crucial role in tear production, and their dysfunction can contribute to dacryoadenitis.
16. Lacrimal scintigraphy: Lacrimal scintigraphy is a nuclear medicine test that evaluates the drainage of tears from the eyes. It helps identify any blockages or abnormalities in the lacrimal drainage system.
17. Lacrimal gland biopsy: In certain cases, a biopsy of the lacrimal gland may be necessary to confirm the diagnosis and identify any specific underlying causes, such as lymphoma or sarcoidosis.
18. Serological tests: Serological tests, including antibody tests and specific antigen tests, may be performed to identify the presence of infectious agents such as bacteria, viruses, or parasites.
19. Allergy testing: Allergy testing may be conducted to determine if an allergic reaction is contributing to the inflammation of the lacrimal gland. This can involve skin prick tests or blood tests to detect specific allergens.
20. Consultation with specialists: Depending on the underlying cause and severity of the dacryoadenitis, a consultation with specialists such as ophthalmologists, oculoplastic surgeons, rheumatologists, or infectious disease specialists may be required to guide further evaluation and management.

It is important to note that the specific diagnostic tests and procedures used for dacryoadenitis may vary depending on the individual patient’s presentation and the suspected underlying cause.

Treatments

The condition can be caused by various factors, including infection, autoimmune disorders, and blockage of the tear ducts. Treatment for dacryoadenitis aims to reduce inflammation, relieve symptoms, and address the underlying cause.

One study suggests that idiopathic dacryoadenitis may respond to surgical debulking, with a low relapse rate.[rx] Refractory cases of inflammatory dacryoadenitis may benefit from orbital radiotherapy, methotrexate, or rituximab. IgG4-related disease has a high rate of remission with rituximab, but this effect may be temporary.[rx]

Management of IgG4-related dacryoadenitis is still debated. An initial trial of corticosteroids is reasonable. Immunosuppression is only rarely necessary. There are reports suggesting that sclerosing dacryoadenitis that is associated with IgG4 can go on to develop lymphoma.[rx]
