Why Are My Eyelashes Turning Inward?

Patients feel a constant scratch or the sense that an eyelash is in the eye that they cannot flush out, and the eye stays red and watery no matter what drops they try. Some can see a lash or two curling inward in the mirror. Because it feels like a persistent foreign body and the eye looks irritated, they want to know why the lashes are pointing the wrong way and how to stop the scratching for good.

Normally lashes grow outward, forming a protective fringe. In trichiasis, one or more lashes are aimed inward so their tips drag across the cornea and conjunctiva with every blink — a direct mechanical irritation of the eye's most sensitive surface.

This produces the classic scratchy, painful, watery, light-sensitive eye. Even a single misdirected lash can cause real discomfort and a corneal abrasion. If many lashes rub, or the problem persists, the cornea can develop scarring or become infected, which can blur or threaten vision. The eye itself is usually structurally normal — the problem is lashes pointing the wrong way — but the surface takes the damage.

It is important to separate two situations. In true trichiasis, the lid is in normal position but individual lash follicles are misdirected, so scattered lashes grow inward. This commonly follows chronic blepharitis (inflammation of the lash line), previous eyelid injury or surgery, styes, and scarring conditions of the lid margin. In entropion, the lid margin itself rolls inward and carries otherwise normal lashes against the eye; this is usually age-related laxity but can be scarring-related.

Scarring diseases deserve mention because they can cause both misdirected lashes and cicatricial entropion: chronic inflammation, autoimmune conditions such as ocular cicatricial pemphigoid, chemical or thermal burns, and, worldwide, trachoma, a leading infectious cause of in-turned lashes and blindness. Whatever the source, the shared result is lashes abrading the cornea, with the same symptoms and risk of abrasion, scarring, and infection. Distinguishing misdirected lashes from a turned-in lid — and identifying any scarring cause — determines whether the fix targets the lashes, the lid, or both.

Rubbing lashes always warrant attention, but seek prompt care if you have:

• Increasing eye pain, redness, or light sensitivity
• A white or gray spot on the cornea (possible ulcer)
• Discharge or worsening blurred vision
• Symptoms that persist despite removing a visible lash

A corneal abrasion that becomes infected or ulcerates can threaten vision and needs urgent evaluation. Recurrent in-turned lashes from a scarring condition also need timely specialist care.

Using the slit lamp, the doctor identifies exactly which lashes are misdirected and, crucially, checks whether the lid margin itself is turned inward (entropion) or in normal position (isolated trichiasis). The lid margin is examined for blepharitis and scarring, and the inner lining of the lid is inspected for scarring that points to causes such as pemphigoid or trachoma. The cornea is stained and examined for abrasions, scarring, or an ulcer from the rubbing lashes. This distinction — misdirected lashes versus turned-in lid, scarring versus not — guides which treatment is chosen.

For a few misdirected lashes, options range from simple to definitive. Epilation (plucking) gives quick relief but the lashes regrow within weeks. For lasting control of individual lashes, the follicle can be destroyed with electrolysis, radiofrequency, or laser (argon) ablation; cryotherapy can treat a larger cluster. A bandage contact lens and lubrication can protect the cornea in the meantime.

When the underlying problem is entropion — the whole lid turned in — the definitive treatment is lid surgery to rotate the margin back to normal, after which the lashes point outward again. Contributing blepharitis is treated with lid hygiene and warm compresses, and scarring conditions such as pemphigoid are managed with specialist care of the underlying disease. Corneal abrasions or infections from the rubbing lashes are treated at the same time.

• Do not rely on repeatedly plucking the lash; it regrows in a few weeks and the scratching returns.
• Do not try to trim or burn lashes yourself or dig at the eye to remove them.
• Do not ignore the problem because it comes and goes — the lashes are still abrading the cornea.
• Do not skip lubrication while awaiting treatment, since a dry, scratched cornea is more prone to scarring and infection.
• Do not dismiss new pain, a white corneal spot, discharge, or blurred vision, which suggest an abrasion or ulcer needing urgent care.

Call May Eye Care Center if you keep feeling a lash scratching your eye or can see lashes turning inward, and we can determine whether it is a few misdirected lashes or a turned-in lid and choose a lasting fix rather than repeated plucking. Seek urgent care for increasing pain, a white spot on the eye, discharge, or vision change. Patients across the Hanover area are welcome to schedule an evaluation.

Inward-turning lashes (trichiasis) rub and can scratch the cornea, coming either from misdirected lashes or a turned-in lid; lasting relief means redirecting or destroying the lash roots, or surgically correcting the lid — not endless plucking.
