Overview
What is Blepharitis?
Blepharitis refers to inflammation of the eyelids. Such inflammation can be due to bacterial infections (e.g. staphylococcus), parasites (mites) infestations or can be related to other causes such as acne rosacea or seborrheic dermatitis (dandruff). It can also be a result of a combination of the factors mentioned above.
There are two main types of blepharitis:
1. Anterior Blepharitis - this involves the external portion of the eyelid, where the eyelashes grow.
Debris and crustings of eyelashes.
2. Posterior Blepharitis - this involves the inner eyelid, the part which is in close contact with the eyeball. Meibomian glands that produce the oily layer of the tears are located here. This oily secretion helps to prevent excessive tear evaporation from the eye. Inflammation of this area will result in blockage or dysfunction of the meibomian glands, often resulting in some irritating eye symptoms as mentioned below.

Blepharitis frequently involves both eyes, and may become chronic with delay in treatment.

Complete resolution of blepharitis may be difficult.
Treatment often takes prolonged periods of time.
