The outermost layer is the oil layer, also known as the lipid layer, the layer produced by the meibomian glands. Then, the aqueous layer sits on top, supplied by the lacrimal glands (located near your eyebrows), providing most of the moisture to your eye. At its base is the mucin layer, produced by corneal and conjunctival cells dedicated to mucous production. Your tear film is a triple layer of fluids that functions to keep the elements off your eyes. Dry Eye & Blepharitisĭry eye syndrome is more a group of unpleasant symptoms than a disease with a single cause, so blepharitis isn’t necessarily linked to all dry eye subtypes. When meibomian glands aren’t functioning right, dry eye syndrome might not be far off. In fact, posterior blepharitis also goes by the name meibomian gland dysfunction, and it’s more common than the other types of blepharitis.

It may be a result of skin conditions like rosacea or dandruff of the scalp. The dry, exposed inner surface of the meibomian glands’ canals makes for a decent bacterial breeding ground. Posterior blepharitis is caused by the irregular production of oil in the eyelids (meibomian blepharitis). In some cases, blepharitis can develop due to allergies or a mite infestation. Excessive amounts of bacteria in the eyelids can cause infection. Anterior BlepharitisĪnterior blepharitis is usually caused by bacteria (staphylococcal blepharitis) or scalp and eyebrow dandruff (seborrheic blepharitis). A comorbidity is a term used to point out when two diseases often accompany one another in a patient, but neither really causes the other. This eye condition can affect people of all ages, and it can have different causes or comorbidities depending on its type. Meibomian blepharitis: patients develop a blockage in the oil glands of their eyelids, along with unsatisfactory tear quality and redness on the lining of the eyelids.īlepharitis is more common among people with dry skin, acne, diabetes (via evaporative dry eye), or poor hygiene.At worst, your cornea (the transparent front covering of the eyeball) suffers from inflammation. Patients may also lose eyelashes or experience a distortion of the eyelids’ front edges, often with chronic tearing. Removing these crusts leaves tiny sores that ooze and bleed. Ulcerative blepharitis: patients have matted, brittle crusts around the eyelashes.Seborrheic blepharitis: patients have scale-like oily flakes around the bottom of their eyelashes and pink or red eyelids.Staphylococcal blepharitis: patients frequently exhibit mildly sticky eyelids, thicker lid margins, and lost or askew eyelashes.But different types of blepharitis have slightly different symptoms: Blepharitis SymptomsĪn optometrist can blepharitis based on the appearance of the eyelid margins. Staphylococcal blepharitis and seborrheic blepharitis belong to the anterior variety, while ulcerative blepharitis and meibomian blepharitis belong to posterior blepharitis.
Anterior blepharitis persists at the eyelids’ outer front edge where the eyelashes are, while posterior blepharitis occurs in the inner edge of the eyelid that’s connected to the eye. There are two types of blepharitis: anterior and posterior. Regardless of type, common symptoms include a burning sensation in the eyes, excessive tearing, itching, red and swollen eyelids, dry eyes, and crusty eyelids. While uncomfortable, It’s not contagious and has no impact on the patient’s total vision. It all starts with learning about blepharitis and its causes! What is Blepharitis?īlepharitis is a common eye disease caused by a bacterial infection or skin conditions like scalp dandruff or rosacea.

Whether through dry eye treatments or vision therapy after emergency eye care, knowing what can be done and how to recover can go a long way. One thing that all blepharitis seems to have in common involves infections surrounding your eyelids, but as to why, how, or when it can develop depends on multiple factors, including skin-health issues.īut your optometrist can locate the problem in a routine eye exam, or even an emergency eye care visit, for patients in pain and distress. Blepharitis is an uncomfortable condition that can affect people in complicated ways.
