Could Demodex Be Behind Your Persistent Eyelid Irritation?

If artificial tears ease the gritty feeling in your eyes but the edges of your eyelids still itch, that distinction is worth mentioning at your next eye exam. At Dussan Eye Care in Long Island City, we look closely at where the irritation starts. An itch that keeps returning to the base of your lashes can be a clue to a condition called Demodex blepharitis.

How Demodex Can Affect Your Eyelids

Demodex mites are microscopic organisms that commonly live in hair follicles, including those around your eyelashes. Many people have them without any discomfort. When the mites become too numerous, however, the tissue around the lash roots can become inflamed. We call this inflammation Demodex blepharitis.

It’s easy to mistake the symptoms for dry eye or allergies. You can also have dry eye and eyelid inflammation at the same time. That can explain why lubricating drops soothe some of your discomfort while the itching persists.

Symptoms Worth Mentioning at Your Eye Exam

Think about what you notice when you first wake up and what bothers you later in the day. A few details can help us narrow down the cause:

• Itching that feels strongest right where your eyelashes grow

• Crusty lashes or eyelids that feel stuck together in the morning

• Redness or puffiness along the edges of your eyelids

• A sandy or burning sensation that keeps coming back

What We Look for Along the Lash Line

At our Long Island City office, we use a lighted microscope called a slit lamp to examine your eyelids. We may ask you to look down so we can see the roots of your upper lashes. One telltale sign is a tiny cuff of waxy debris wrapped around the base of an individual lash. These cuffs, called collarettes, are easier to see under magnification than in a bathroom mirror.

We also check the oil glands along your eyelids. If those glands are blocked, your tears may evaporate too quickly. That finding helps us decide whether your care should address dry eye as well as the mites.

How We Treat Demodex Blepharitis

If we confirm Demodex blepharitis, we can discuss prescription lotilaner eye drops, which target the mites directly. If debris has built up along your lashes, we may also recommend an in-office eyelid cleaning. At a follow-up visit, we can compare how your lash line looks with how your eyelids feel and adjust your care if irritation persists.
