Blepharitis

DEFINITION

Blepharitis (blef-uh-RYE-tis) is inflammation of the eyelids. Blepharitis usually involves the part of the eyelid where the eyelashes grow and affects both eyelids.

Blepharitis commonly occurs when tiny oil glands located near the base of the eyelashes become clogged. This leads to irritated and red eyes. Several diseases and conditions can cause blepharitis.

Blepharitis is often a chronic condition that is difficult to treat. Blepharitis can be uncomfortable and may be unsightly. But it usually doesn’t cause permanent damage to your eyesight, and it’s not contagious.

CAUSES

The exact cause of blepharitis isn’t clear. It may be associated with one or more factors, including:

  • Seborrheic dermatitis — dandruff of the scalp and eyebrows
  • A bacterial infection
  • Clogged or malfunctioning oil glands in your eyelids
  • Rosacea — a skin condition characterized by facial redness
  • Allergies, including allergic reactions to eye medications, contact lens solutions or eye makeup
  • Eyelash mites or lice



SYMPTOMS

Blepharitis symptoms and signs include:

  • Watery eyes
  • Red eyes
  • A gritty, burning or stinging sensation in the eyes
  • Eyelids that appear greasy
  • Itchy eyelids
  • Red, swollen eyelids
  • Flaking of the skin around the eyes
  • Crusted eyelashes upon awakening
  • Eyelid sticking
  • More frequent blinking
  • Sensitivity to light
  • Eyelashes that grow abnormally (misdirected eyelashes)
  • Loss of eyelashes

When to see a doctor

If you have blepharitis symptoms and signs that don’t seem to be improving despite good hygiene — regular cleaning and care of the affected area — make an appointment with your doctor.
