Lacrimal Gland Prolapse
Lacrimal gland prolapse is a condition in which the lacrimal gland moves forward or downward from its normal anatomical position within the upper outer orbit. It may appear as upper eyelid fullness, temporal orbital swelling, or a cosmetic asymmetry and is often associated with aging, tissue laxity, or changes in orbital support structures.
What Is Lacrimal Gland Prolapse?
Lacrimal gland prolapse occurs when the lacrimal gland becomes displaced from its normal position in the superolateral orbit.
The lacrimal gland normally rests within the lacrimal fossa of the frontal bone and is supported by surrounding connective tissues, orbital structures, and the eyelid anatomy.
When these supporting structures weaken, stretch, or become disrupted, the gland may descend or shift forward, creating visible fullness in the upper outer eyelid.
Lacrimal gland prolapse is usually a benign condition but may resemble other orbital masses and should be evaluated carefully.
Lacrimal Gland Anatomy
The lacrimal gland is an important structure of the ocular adnexa responsible for producing the watery component of tears.
Main Lacrimal Gland
Located in the upper outer orbit and responsible for most reflex tear production.
Orbital Lobe
The larger portion located within the lacrimal fossa.
Palpebral Lobe
The smaller portion extending toward the upper eyelid.
Lacrimal Ducts
Small channels that deliver tears onto the ocular surface.
Normal Lacrimal Gland Position & Support
The lacrimal gland remains in place through a combination of anatomical structures that provide stability.
Lacrimal Fossa
A bony depression in the frontal bone that houses the gland.
Suspensory Ligaments
Connective tissues help maintain gland position.
Orbital Septum
Provides anterior support between orbital contents and eyelid tissues.
Eyelid Structures
The upper eyelid contributes to maintaining normal orbital anatomy.
Understanding Lacrimal Gland Displacement
Lacrimal gland prolapse occurs when normal anatomical support becomes insufficient, allowing the gland to move from its original position.
Tissue Relaxation
Age-related changes may weaken connective tissue support.
Anterior Movement
The gland may become more visible beneath the eyelid.
Upper Eyelid Fullness
Patients may notice a bulge or heaviness near the outer eyelid.
Cosmetic Asymmetry
The appearance may differ between the two eyes.
How Lacrimal Gland Prolapse Develops
The condition develops when the normal balance between orbital support and tissue mobility changes.
Support Weakening
Connective tissues become less effective at holding the gland in position.
Gland Displacement
The lacrimal gland moves away from its normal location.
Visible Fullness
The displaced gland creates upper eyelid contour changes.
Functional Effects
Some patients may experience discomfort or altered tear distribution.
Types of Lacrimal Gland Prolapse
Lacrimal gland prolapse may be classified according to cause and clinical setting.
Age-Related Prolapse
Occurs due to weakening of orbital and eyelid support structures over time.
Congenital Prolapse
Present from birth due to developmental differences in orbital anatomy.
Traumatic Prolapse
May occur after injury affecting orbital support tissues.
Post-Surgical Prolapse
May develop after procedures affecting eyelid or orbital anatomy.
Unilateral Prolapse
Affects one eye and may cause visible asymmetry.
Bilateral Prolapse
Affects both eyes and is often related to generalized tissue changes.
Causes of Lacrimal Gland Prolapse
Several anatomical and mechanical factors can contribute to displacement of the lacrimal gland.
Aging Changes
Loss of tissue elasticity may weaken gland support.
Eyelid Laxity
Changes in eyelid support can alter orbital anatomy.
Orbital Tissue Relaxation
Soft tissue changes may allow gland movement.
Trauma
Injury may disrupt normal support structures.
Anatomical Factors
Weakening of Support Ligaments
Reduced connective tissue strength may allow displacement.

Monitor Appearance
Changes in eyelid contour or increasing fullness should be reassessed.
Evaluate Symptoms
New discomfort, tearing changes, or vision symptoms require further evaluation.
Exclude Other Disease
Progressive enlargement should not automatically be assumed to be simple prolapse.
Conservative Management
Conservative management focuses on improving comfort and addressing associated eyelid or ocular surface issues.
Ocular Surface Care
Artificial tears may help if tear film irritation is present.
Eyelid Care
Management of associated eyelid conditions may improve symptoms.
Cosmetic Counseling
Patients should understand expected changes and available options.
Lubrication & Ocular Surface Protection
Although lacrimal gland prolapse is primarily an anatomical condition, associated ocular surface symptoms may require treatment.
Artificial Tears
Help relieve irritation caused by tear film instability.
Dry Eye Management
Patients with reduced tear quality may benefit from ocular surface therapy.
Environmental Protection

- Ocular discomfort
- Tear film disturbance
- Difficulty with eyelid comfort
- Possible dry eye symptoms
Cosmetic Complications
- Upper outer eyelid fullness
- Facial asymmetry
- Aged eyelid appearance
- Visible temporal bulging
- Patient dissatisfaction with appearance
Important Diagnostic Considerations
Not every upper outer eyelid fullness represents lacrimal gland prolapse. Other orbital conditions may appear similar and should be considered.
Lacrimal Gland Tumor
A mass involving the lacrimal gland may mimic prolapse and requires evaluation.
Dacryoadenitis
Inflammation may enlarge the gland and cause swelling.
Orbital Fat Prolapse
Displacement of orbital fat may create similar eyelid fullness.
Dermatochalasis
Excess eyelid skin can contribute to upper eyelid heaviness.
Emergency Warning Signs
Lacrimal gland prolapse itself is usually not an emergency. However, sudden changes or concerning symptoms require prompt evaluation.
Rapid Growth
Sudden enlargement may indicate inflammation or another orbital process.
Pain or Tenderness
Pain is not typical of simple prolapse and may suggest inflammation.
Vision Changes
New vision loss, double vision, or visual disturbance requires evaluation.
Eye Movement Limitation
Restriction may indicate deeper orbital involvement.
Severe Redness
May suggest inflammatory or infectious disease.
Sudden Asymmetry
New rapid changes should not be assumed to be normal aging.
Prognosis
The prognosis of lacrimal gland prolapse is generally excellent because the condition is benign and does not usually threaten vision.
Mild Prolapse
Often remains stable and may only require observation.
Surgical Correction
Many patients achieve improved eyelid contour after appropriate repair.
Associated Aging Changes
Outcome depends on management of additional eyelid and orbital changes.
Long-Term Stability
Follow-up helps identify recurrence or progressive changes.
Factors Affecting Outcome
Severity of Prolapse
Greater displacement may require more extensive correction.
Associated Eyelid Changes
Dermatochalasis and laxity influence appearance and treatment.
Underlying Anatomy
Individual orbital structure affects surgical planning.
Preservation of Tear Function
Maintaining lacrimal gland function is an important goal.
