As of 2015, there are pictures of the part of the eye affected by blepharitis available at MayoClinic.org, AAFP.org, and GetEyeSmart.com. Blepharitis is inflammation of the eyelid.
Blepharitis is caused by the sebaceous glands of the eyelashes, also known as the glands of Zeis, becoming clogged. This clogging can occur for a number of reasons, including bacterial infection. The clogging of these glands affects the entire eyelid, causing it to develop a red and puffy appearance, Other visual hallmarks of blepharitis include pale, encrusted discharge along the margins of the eye, thickened eyelids, and eyelids that turn outward or inward.
