Overview
Blepharitis may be classified according to the anatomic location of the disease into 2 subtypes: anterior or posterior. Additionally, blepharitis may be classified based on the duration of symptoms into either acute or chronic.[1][2]
Classification
Based on the anatomic location, blepharitis may be classified into:[1][2][3][4]
- Anterior blepharitis (affects the front of the eyelids near the base of the eyelashes, eyelid skin, and the eyelash follicles)
- Staphylococcal blepharitis
- Seborrheic blepharitis (mainly anterior lid)
- Posterior blepharitis ( affects the back of the eyelids, tarsal plate, meibomian glands, and gland orifices)
- Meibomian gland dysfunction (MGD)
- Seborrheic blepharitis
Based on the duration of symptoms, blepharitis may be classified into:[5]
- Chronic blepharitis (Most often blepharitis is a waxing and waning chronic condition)
- Acute blepharitis (allergen or irritant exposure)
