Blepharitis

Eyelid inflammation; Meibomian gland dysfunction

Blepharitis is manifest by inflamed, irritated, itchy, and reddened eyelids. It most often occurs where the eyelashes grow. Dandruff-like debris builds up at the base of the eyelashes as well.

Eye

The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.

Blepharitis

Blepharitis is an inflammation of the lash follicles at the eyelid margins due to excess growth in lash follicles of bacteria normally present on the skin.
