What are the symptoms and causes of Blepharitis?


What is Blepharitis?

Blepharitis is an inflammation of the eyelids. It usually affects the edges (margins) on the eyelids. It is not usually serious, but can be an uncomfortable, irritating issue. Blepharitis is typically continual (persistent). Both eyes are generally affected.

Blepharitis is one common eye condition, causing the eyelids for being reddened, itchy, and somewhat swollen and scaly-appearing at the base of the lashes. It is the most frequent cause of dry sight. A dysfunction of your eyelid’s oil glands leading to blepharitis occurs because of a hormone imbalance.

What are the causes of blepharitis?

You will find three main types of blepharitis: staphylococcal blepharitis, seborrhoeic blepharitis in addition to meibomian blepharitis. All three types may cause similar symptoms.

causes of Blepharitis

Staphylococcal blepharitis

This kind of blepharitis is thought to be caused by a bacterium (germ) called staphylococcus. This bacterium commonly lives in low numbers about the skin without doing almost any harm. However, in some people, it seems that this particular bacterium causes a localised infection on the eyelids, resulting in blepharitis. Why this happens in some people is unclear.

Seborrhoeic blepharitis

Seborrhoeic blepharitis is closely associated with a skin condition called seborrhoeic dermatitis. Inside seborrhoeic dermatitis, the affected skin becomes more oily and may become scaly. Seborrhoeic dermatitis generally causes bad dandruff in addition to sometimes a rash, commonly about the face and upper human body. The underlying cause of seborrhoeic dermatitis is not clear.

A type regarding yeast called Malassezia furfur can be involved. However, it is not just a simple skin infection which is not contagious (you cannot catch treatment plans from others). This yeast lives inside sebum (oil) of human skin for most adults and usually can no harm. However, in certain people the yeast may seem to trigger an inflammatory reaction, causing the blepharitis.

Meibomian blepharitis

This is also called meibomian gland dysfunction. The tiny meibomian glands inside eyelids lie just at the rear of the eyelashes. You possess about 25-30 meibomian glands upon each upper and reduced eyelid. They make a small amount of oily fluid which comes out within the eyelids next towards eye. This oily fluid kinds the outer layer on the tear film which lubricates the front of the eye. People with meibomian blepharitis are thought to get a slight problem with their meibomian glands as well as the fluid they produce. This can result in eyelid inflammation.
