Blepharitis, Symptoms and Causes
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 the one’s life. Often, there is a secondary infection of the eye and a loss of eyelashes.
The following are the most common symptoms of blepharitis. However, each person may experience symptoms differently. Blepharitis symptoms may include:
- Redness and scaling on the edges of the eyelids
- Burning of the eyes
- Itching of the eyes
- 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
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), or it may be associated with seborrhea. Seborrheic dermatitis is an inflammation of the skin's top layers that is characterized by red, itchy skin that sheds scales.
