Posterior affects the meibomian glands at the back of the eyelids. Anterior concentrates at the base of the eyelashes and mostly disrupts the front portion of the eyelids.
There are two forms of eyelid inflammation, anterior and posterior. Because we know that eyelid inflammation is a major cause of dryness, we often see that most of our patients with dryness have some form of eyelid inflammation. When bacteria invade, the body begins to do what it can to fight off infection and brings about redness, itching, and sometimes pain. An overload of bacteria is the number one cause for inflammation of the eyelids. Inflammation is often just one piece of the puzzle, but where does it come from? In many cases, bacteria is to blame. Many of you with dryness will recognize some of these signs as being things that you deal with on a regular basis. Inflammation in general will bring about a few things redness, swelling, heat, pain, and loss of function. While acute inflammation can be a good thing, chronic inflammation can be very hard on your body. This is a normal process and your body’s way of healing itself. By definition, inflammation is your body’s process for fighting offending agents (which may be due to injury, infection, toxins, or other reasons).
When your eyes become red and irritated, it means there is inflammation present.
