Entropion is a temporary or permanent malposition of one or both eyelids in which the lid turns inward. As a result, the eyelashes rub against the surface of the eye, which can lead to irritation and injury. Entropion can affect both the upper and lower eyelids, although the lower eyelid is more commonly affected.
Typical symptoms include red, watery, or painful eyes, as well as inflammation of the conjunctiva or cornea. Causes may include age-related changes, muscle or nerve disorders, and scarring.
Below you will find more information on symptoms, causes, and treatment options, as well as a selection of entropion specialists.
What is entropion?
An entropion is more than just a bothersome eyelid malposition. When the eyelid turns inward, the eyelashes and the edge of the eyelid rub against the sensitive surface of the eye with every blink. For those affected, this often begins with a persistent sensation of a foreign body in the eye, watery eyes, or sensitivity to light. If the underlying cause remains untreated, irritation, inflammation, and damage to the cornea can result. This is precisely why it’s important to have entropion evaluated by an ophthalmologist at an early stage. As a type of eyelid malposition, it is one of the conditions that are specifically diagnosed and treated in ophthalmology.
Typical Symptoms and Risks
Typically, patients complain of a burning or stinging sensation, red eyes, and constant tearing. Many describe the feeling as if there were sand in their eye. Some reflexively squint, which can further exacerbate the symptoms. Entropion becomes particularly problematic when the cornea is subjected to constant mechanical irritation. This can lead to small defects on the corneal surface, infections, ulcers, and later even scarring, all of which can permanently impair vision.
In most cases, entropion is age-related. Over the years, connective tissue and eyelid structures lose their elasticity, causing the eyelid margin to lose its stable position and turn inward. However, there are other causes as well. Scarring from inflammation, injuries, or previous surgeries can be underlying factors, as can severe eyelid spasm (blepharospasm). Congenital entropion is less common; in many cases, it can be observed initially in infants and toddlers, provided there is no risk of corneal damage. Related eyelid abnormalities such as ectropion or ptosis require a similarly thorough evaluation.
Causes and Diagnosis
An experienced ophthalmologist can usually make the diagnosis quickly. However, the key factor is not only the malposition itself but also the extent to which the conjunctiva and cornea are already affected. Therefore, a thorough evaluation always includes an examination with a slit lamp. This allows the doctor to determine whether there is already superficial corneal damage, conjunctival inflammation, or other accompanying findings that require treatment. Depending on the situation, additional tests may be warranted, such as when scarring, infections, or neurological causes are suspected.
Treatment depends on the cause and severity. Temporarily, the eyelid can be stabilized with special adhesive strips or sutures. Such measures can alleviate symptoms but are usually not a permanent solution for severe or chronic entropion. If the eyelid malposition recurs or the cornea is at risk, surgical correction is often the most appropriate treatment. The goal of the procedure is to return the eyelid to its anatomically correct position so that the eyelashes no longer rub against the eye and the ocular surface is protected.
How is entropion treated?
For those affected, the most important question is often: When should I seek treatment? The honest answer is: not only when the pain becomes severe. Even persistent tearing, constant redness, or the feeling that there is always something in the eye should be taken seriously. Anyone who also experiences blurred vision, is very sensitive to light, or notices recurring inflammation should consult a specialist in eyelid surgery as soon as possible.
At Leading Medicine, patients with eyelid malpositions such as entropion receive care at a specialist and surgical level. For you as a patient, this means: a precise analysis of the cause, an individualized treatment plan, and—if necessary—surgical correction with the goal of alleviating symptoms, protecting the cornea, and restoring natural eyelid function.
When to See a Specialist
If you suspect you have entropion or are already experiencing red, watery, and painful eyes, you should not delay seeking treatment. Early treatment can prevent further damage and often significantly improve your quality of life. Through the Leading Medicine Guide, you can request an appointment directly and have your symptoms evaluated by a team specializing in eyelid disorders.
