What is blepharitis ?

Blepharitis is a medical disorder that leads to inflammation of the eyelids. Blepharitis normally occurs on the outer end of the eyelids, where there is growth of eyelashes.

Blepharitis is sometime known by another name, i.e. Granulated eyelids. Blepharitis that mainly occurs on the outer corners of the eyelids is known as angular blepharitis.

Blepharitis occurs when the small oil glands of eyelashes situated at lower end the eyelids fail to carry out their functions. Such inaction leads to inflammation of the eyelids which then causes them to become itchy, reddish, irritating; and collect scales which appear like dandruff on eyelashes.

Though blepharitis is not contagious and does not cause permanent harm to vision, it inflicts discomfort, is distressing and unattractive to look at. It is a condition that can affect individuals of all age groups and has a tendency to recur. Hence the treatment and management of blepharitis is often difficult.

Symptoms of Blepharitis

Blepharitis can occur on the lower and upper eyelids and may affect either one or both the eyes. Some of the symptoms of blepharitis are mentioned below:

  • Watery eyes
  • There may be increased redness of the eyelid borders
  • Itchy eyelids
  • A feeling of increased burning of the eyes
  • A feeling of excessive grittiness in the eyes
  • Increased redness of the eyes as well
  • A feeling of increased sandiness of the eyes
  • Swollen eyelids
  • The eyelids may tend to look greasy, may be crusted with scales that fasten on to the eyelids.
  • The skin cells present around the eyes may experience more shedding causing patches of dry and flaky skin around the eye. The eyelid may also get affected and have flaky and dry skin.
  • Increased sensitivity to light
  • Loss of eyelashes
  • Abnormal growth of eyelashes
  • A sensation of a foreign body presence in eye
  • Increased crusting of eyelids
  • Irritation in eye and in eyelids
  • One may feel increased uneasiness in wearing contact lenses
  • The eyelids may glue together in morning and the lashes may matt together
  • Increasingly frothy and bubbly state of tears
  • The eyelid margins may face slight or mild ulceration
  • Affected individuals may wake up to find their eyes crusted
  • The eyelid margins may face slight or mild scarring
  • Presence of dandruff over eyebrows and eye lashes

Some of the complications that may result from blepharitis are:

  • Chronic and long term blepharitis may cause permanent eyelid skin problem and scarring on eyelids.
  • Blepharitis may cause long-term conjunctivitis or recurrent episodes of pink eye
  • Sty infection may develop near the base of the eyelashes causing the formation of a lump inside the eyelids or on its edge which is painful. A sty on eyelids has an odd look to it and clearly visible.
  • Misdirected and abnormal eyelashes and chronic inflammation can cause formation of an ulcer or a sore in the cornea. Corneal infection is common with deficient lubrication or tearing.
  • When the tiny oil glands present on the eyelid borders get blocked, it may cause the formation of a chalazion and bacterial infection of the gland resulting in swollen and reddish eyelid. The chalazion tends to be more prominent and visible on inside of the eyelid in comparison with a sty.
  • Blepharitis may cause the abnormal secretion and collection of debris such as flakes and dandruff shed from the eyelids, on the tear film. The tear film forms the tears along with the oil, water and mucus solution. The abnormalities prevent providing the lubrication required for the eyes and eyelids, which causes irritation and increased tearing.
