From the Guidelines

Chronic swollen eyelids are typically caused by conditions like blepharitis, which is often associated with meibomian gland dysfunction (MGD) and can be managed with warm compresses, artificial tears, and eyelid cleansing. The underlying causes of chronic swollen eyelids can be complex and multifactorial, involving a combination of factors such as blocked oil glands, allergic reactions, and underlying skin conditions 1.

Key Causes and Management Strategies

  • Blepharitis, a condition characterized by eyelid inflammation, is a common cause of chronic swollen eyelids 1
  • Meibomian gland dysfunction (MGD) is often associated with blepharitis and can contribute to chronic eyelid swelling 1
  • Warm compresses, applied to closed eyes for several minutes, can help soften adherent scurf and scales, and warm the meibomian secretions, providing symptomatic relief for posterior blepharitis/MGD 1
  • Eyelid cleansing, including eyelid massage, can be especially useful for anterior blepharitis, and can be accomplished using diluted baby shampoo or commercial eyelid cleansers 1

Treatment Approaches

  • A combination of warm compresses, artificial tears, and eyelid cleansing is often recommended as an initial treatment approach for chronic swollen eyelids 1
  • Topical antibiotics, antiparasitic medication, and anti-inflammatory agents may be used in conjunction with these treatments, depending on the underlying cause of the condition 1
  • In-office procedural treatments, such as vectored thermal pulsation and microblepharoexfoliation, may also be considered for patients with persistent symptoms 1

Importance of Patient Education and Counseling

  • Proper counseling of patients with chronic swollen eyelids is essential to ensure they understand the importance of regular eyelid hygiene and the potential need for ongoing treatment 1
  • Patients should be instructed on how to safely perform eyelid cleansing and warm compresses, and how to avoid potential complications, such as burning the skin with hot compresses 1

From the Research

Causes of Chronic Swollen Eyelids (Blepharitis)

  • Chronic swollen eyelids, also known as blepharitis, can be caused by various factors, including:
    • Allergic reactions, such as allergic conjunctivitis 2
    • Inflammatory conditions, such as contact dermatitis, eczema, and angioedema 3
    • Infectious diseases, such as acute sinusitis 3
    • Systemic diseases, such as thyroid eye disease, Sjögren's syndrome, and Churg-Strauss vasculitis 3, 4
    • Dermatologic conditions, such as eyelid dermatitis and urticaria 5
  • Other possible causes of chronic swollen eyelids include:
    • Blepharitis itself, which can be caused by a combination of factors, including poor eyelid hygiene, Demodex mites, and meibomian gland dysfunction
    • Orbital and ocular lymphoid hyperplasia or adnexal lymphoma 3
    • IgG4-related diseases 3
  • It is essential to note that the diagnosis of chronic swollen eyelids requires a comprehensive evaluation of the patient's medical history, physical examination, and laboratory tests to determine the underlying cause 3, 6
