Entropion

What is entropion?

Entropion is a medical condition in which the eyelid, usually the lower one, turns inward toward the eyeball. This inward rolling causes the eyelashes and skin to rub against the surface of the eye, leading to irritation, discomfort, and potential damage to the cornea. Although entropion can affect anyone, it is most commonly seen in older adults due to age-related changes in the muscles and tissues around the eyelids.

What are the different types of entropion?

There are several types of entropion. Involutional entropion, the most common form, occurs as the eyelid tissues weaken with age. Congenital entropion is present at birth and may be caused by abnormal development of the eyelid. Cicatricial entropion results from scarring on the inner surface of the eyelid, often due to trauma, infection, or inflammatory diseases. Spastic entropion can happen when eyelid spasms or irritation temporarily cause the lid to roll inward.

What are the the symptoms of entropion?

The symptoms of entropion typically include redness, tearing, eye irritation, a sensation of something in the eye, and sensitivity to light or wind. Over time, constant friction from the eyelashes can lead to corneal abrasions, ulcers, or even vision loss if left untreated. Because of these risks, prompt diagnosis and management are important.

How is entropion treated?

Treatment options depend on the underlying cause and severity of the condition. Temporary measures may include lubricating eye drops or ointments to protect the cornea, as well as tape or sutures to reposition the eyelid. Botulinum toxin injections can also be used to temporarily relax the eyelid muscles. However, surgical correction is often the most effective and long-term solution. During surgery, the eyelid is tightened or repositioned to restore its normal alignment and protect the eye.

Can entropion be prevented?

Prevention may not always be possible, especially in age-related cases, but early detection can reduce complications. Anyone experiencing persistent eye irritation or changes in eyelid position should seek prompt evaluation from an ophthalmologist. With appropriate treatment, most patients experience significant relief and preservation of their vision.
