Anterior blepharitis affects the margins of the eyelids and the area where the eyelashes that are attached to the eyelid while posterior blepharitis occurs in the inside area of the eyelid where the oil secreting glands are found. The sebum secreting glands are called Meibomian glands.

Causes of posterior blepharitis

Posterior blepharitis can be caused by seborrhea dermatitis or dandruff and acne rosacea since the Meibomian glands are found in these area. They hide an oily substance which is a component of tears that protects the eyes and helps the tear film stay over the eye.

A burning sensation can be felt in the eyes.

Posterior blepharitis occurs when the Meibomian glands are affected. They secrete more or reduced amount of sebum and seborrhea dermatitis develops when there is an excess production of oil which is the best place for bacteria to grow.

Acne rosacea minimizes the production of oil which causes the evaporation of tears and cause eyes to dry. Those who are suffering from rosacea have eye symptoms.

Symptoms of posterior blepharitis may be acute or chronic. It can recur from time to time with periods of remissions. This condition can affect both the eyes and the symptoms are usually severe in the morning upon waking up. Some common symptoms of posterior blepharitis include the following:
