Eyelashes that turn inward, medically known as trichiasis, can be uncomfortable and potentially harmful to the eye. This condition occurs when the eyelashes grow towards the eyeball instead of away from it. Several underlying factors can cause this misdirection.
Key Causes of Inward-Turning Eyelashes
According to medical information, the primary causes for eyelashes turning inward often relate to inflammation, infection, or structural changes of the eyelids.
Based on the provided information, specific causes include:
- Chronic Blepharitis: Long-term or recurring inflammation of the eyelids, known as chronic blepharitis, is a common cause that can lead to your eyelashes becoming misdirected.
- Infections: Certain infections can cause eyelashes to point towards your eye. A notable example is Trachoma, a bacterial infection prevalent worldwide that can lead to significant eyelid scarring and lash misdirection.
- Entropion: This is a condition where the eyelid itself turns inward. When the eyelid is pointing towards the eye, it inevitably causes your eyelashes to also point in the same direction, rubbing against the cornea.
How These Conditions Affect Eyelash Growth
These conditions impact the eyelid structure and the hair follicles, leading to abnormal lash growth direction.
- Blepharitis: Chronic inflammation can disrupt the natural growth pattern of the lashes.
- Infections (like Trachoma): Severe infections can cause scarring on the inner surface of the eyelid, which pulls the lashes inwards.
- Entropion: The mechanical turning-in of the eyelid margin physically forces the lashes to scrape against the eye.
Understanding the Impact
When eyelashes turn inward, they can constantly rub against the cornea and conjunctiva, the clear front surface of the eye and the membrane covering the white part. This can lead to:
- Eye irritation and redness
- Feeling like something is in your eye
- Excessive tearing
- Sensitivity to light
- Corneal abrasions or ulcers, which can potentially impair vision if left untreated
Solutions and Management
Managing inward-turning eyelashes typically involves addressing the underlying cause and the misdirected lashes themselves. While specific treatments depend on the diagnosis, options may include:
- Manual removal of lashes (temporary relief)
- Electrolysis or cryotherapy to permanently remove lashes
- Surgery to correct eyelid position (especially for entropion)
- Treatment for underlying conditions like blepharitis or infections
It is important to consult an eye care professional for a proper diagnosis and treatment plan if you experience symptoms of eyelashes turning inward.
