Medicines for Entropion

What it is

Entropion is a condition in which an eyelid (most often the lower lid) turns inwards, so that the eyelashes and skin rub against the surface of the eye. This causes irritation and a feeling of something in the eye, redness, watering, sensitivity to light, and discomfort, and the constant rubbing of the lashes on the cornea can, if not treated, damage the eye's surface over time. It is most common in older people, as the tissues and muscles of the eyelid weaken and become lax with age; it can also result from scarring of the inner eyelid (for example after infection or inflammation), and, less commonly, from other causes. It usually develops gradually. While often uncomfortable rather than dangerous, because the lashes rubbing on the cornea can cause damage, entropion is worth assessing and treating. It is diagnosed by examining the eyelid.

How it is treated

Management aims to relieve the irritation and stop the lashes rubbing on the eye, protecting the surface. In the short term, lubricating eye drops or ointment soothe the eye and protect its surface, and taping the eyelid or other temporary measures can turn the lid outwards for relief. The definitive treatment for most entropion is a minor operation to correct the position of the eyelid, tightening or repositioning the tissues so the lid turns outwards normally; this is usually effective and often a day-case procedure under local anaesthetic. Any underlying cause (such as scarring) is taken into account. Because the rubbing lashes can damage the cornea, prompt assessment and treatment are worthwhile, especially if the eye is becoming sore or the vision affected. The reassuring message is that entropion is treatable, often with a straightforward operation, which relieves the irritation and protects the eye.
