If you’re experiencing eyelid irritation, you may be wondering about potential causes and treatments. At Premier Vision Group, we know how frustrating this irritation can be, and we’re here to explain what Demodex are and how to find relief.
What Are Demodex Mites?
Demodex are microscopic mites that naturally live on the human body, including the skin on the face and the eyelashes. While their presence is typically harmless, an overgrowth of these mites can contribute to inflammation and irritation around the eyes.
Because Demodex mites are microscopic, they cannot be seen with the naked eye. Eye care professionals can identify signs of Demodex during a comprehensive eye examination using specialized magnification and examination techniques.
What Are the Symptoms of Demodex Blepharitis?
For many individuals, Demodex lives on the skin without causing noticeable symptoms. However, an excessive population can contribute to a condition known as Demodex blepharitis.
Demodex overgrowth can contribute to inflammation of the eyelids and ocular surface. Common symptoms may include:
- Itchy or irritated eyes
- Redness and inflammation along the eyelid margins
- Dry eye symptoms
- Burning or foreign-body sensation
- Fluctuating or blurred vision
- Increased debris or crusting around the eyelashes
- Lash loss or changes in the eyelashes
If you notice any of these symptoms, it’s a good idea to book an eye exam with your eye doctor.
Who Can Get Demodex Blepharitis?
Demodex can be found in individuals of all ages, but the likelihood tends to increase with age. Certain conditions and lifestyle factors may also be associated with a greater risk of developing Demodex overgrowth, including rosacea, certain dermatologic conditions, and eyelid inflammation.
What Happens During an Evaluation?
Because Demodex mites commonly live on human skin, their presence alone does not necessarily indicate poor hygiene or disease. The concern arises when their population becomes excessive or contributes to ocular inflammation and symptoms.
An eye care professional can evaluate the eyelids and eyelashes for clinical signs of Demodex during a comprehensive eye examination. In some cases, an eye care professional may examine eyelashes under magnification to identify the mites directly.
Proper diagnosis is important because symptoms associated with Demodex can overlap with other common conditions, including dry eye disease, meibomian gland dysfunction, allergic conjunctivitis, and other forms of blepharitis.
What Is the Treatment for Demodex Blepharitis?
The good news is that Demodex blepharitis can be managed. Treatment depends on the severity of the condition and the individual’s overall eye health.
Your eye care professional may recommend targeted eyelid hygiene, commercially available Demodex-directed treatments, or other therapies designed to reduce the Demodex population and improve eyelid health and the health of your eye’s surface. Identifying the underlying cause of your symptoms is the first step toward developing an appropriate treatment plan.
