What is blepharitis?

Blepharitis is an inflammation of the eyelash follicles along the edges of the eyelids. This is usually a persistent, recurring problem for children that starts early in childhood and may last throughout one’s life. Often, there is a secondary infection of the eye and a loss of eyelashes.

Symptoms

Symptoms may include:

  • Redness and scaling on the edges of the eyelids
  • Burning, itching and/or swelling of the eyes
  • Rubbing of eyes
  • A feeling of having sand or dust in the eyes when blinking
  • General discomfort of the eyes
  • Seborrheic dermatitis on the head or face
  • Eye drainage

Causes

Blepharitis may be caused by:

  • An overgrowth of bacteria that is normally found on the skin
  • An infection with bacteria
  • Abnormal production and secretion of the sebaceous glands (oil-producing glands)
  • Seborrheic dermatitis (an inflammation of the skin's top layers that is characterized by red, itchy skin that sheds scales)
