How does Blepharitis develop?
Among the most common causes of blepharitis are: * poor eyelid hygiene * excess oil produced by the glands in the eyelid * a bacterial infection (often staphylococcal) * an allergic reaction There are two main types of blepharitis: staphylococcus and seborrhea. Staphylococcus blepharitis is caused by a germ called Staphylococci, commonly known as “staph.” It often begins in childhood and continues throughout adulthood. This form of the condition results in collar scales on lashes, crusting, and chronic redness at the lid margin. Dilated blood vessels, loss of lashes, sties, and chalazia also occur. Seborrhea blepharitis is the most common and least severe form of this condition. It is not an infection but is caused by improper function of the oil glands, which causes greasy, waxy scales to accumulate along the eyelid margins. Seborrhea may be a part of an overall skin disorder that affects other areas. Hormones, nutrition, general physical condition and stress are factors in seborrhea.
