Eyelid Ectropion (Turnout) and Entropion (Turn-In)
Symptoms You May Be Experiencing
If your lower eyelid has started to sag or pull away from the surface of your eye, you are likely dealing with a condition called ectropion. You may have noticed excessive tearing that does not seem to stop, even when you are not emotional or in a windy environment. Many patients describe a persistent burning or gritty sensation along with visible redness of the inner eyelid lining. These symptoms can make everyday activities such as reading, driving, and spending time outdoors uncomfortable, and we want you to know that effective treatment is available.
- Chronic tearing or watery eyes that worsen outdoors
- Redness and irritation along the lower eyelid margin
- A gritty or sandy feeling in the affected eye
- Crusting or discharge that builds up along the eyelid
Entropion is the opposite condition, in which the eyelid margin rolls inward so that your eyelashes rub directly against the surface of your eye. This creates a persistent foreign body sensation, as though something is stuck in your eye that you cannot remove. Because the lashes and skin contact the cornea with every blink, the discomfort tends to be more acute and can interfere with sleep and concentration. If you have been experiencing these symptoms, you are not alone, and we encourage you to have your eyelids evaluated.
- A constant feeling of something in the eye
- Excessive tearing and mucous discharge
- Eye redness and irritation that worsens with blinking
- Light sensitivity and blurred vision if the cornea becomes scratched
If you are experiencing persistent tearing, redness, or a sensation that your eyelid is not sitting properly against your eye, we recommend scheduling an evaluation with our oculoplastic surgeon. It is especially important to seek care if you notice your eyelashes rubbing against your eye, if your vision has become blurry, or if you have developed a sore or raw area on the surface of your eye. Early evaluation can help prevent corneal damage and preserve your comfort and vision. Patients who also notice a droopy eyelid or changes in the appearance of their eyelids should mention these concerns during their visit.
Understanding Ectropion and Entropion
Ectropion occurs when the eyelid margin rotates away from the eye, exposing the inner lining of the eyelid (the palpebral conjunctiva) to the air. This exposure leads to dryness and reflexive tearing because the eyelid can no longer sweep tears across the eye surface effectively. Ectropion affects approximately 2.9 percent of people over 60 years of age (Clinical data, 2025), making it one of the more common eyelid malpositions we see in our practice. Without treatment, chronic ectropion can cause thickening of the exposed conjunctival tissue and, in more advanced cases, corneal damage from prolonged dryness. Patients with watery eyes often discover that ectropion is the underlying cause of their symptoms.
Entropion is the inward turning of the eyelid margin, causing the eyelashes and skin to rub directly against the cornea and conjunctiva. This constant friction creates irritation, corneal abrasions, and, if left untreated, scarring that may threaten your vision over time. Involutional entropion has a prevalence of approximately 2.1 percent in people over 60 years of age (EyeWiki, 2024). The lower eyelid is involved in approximately 95 percent of cases, though the upper eyelid can also be affected.
Although ectropion and entropion both result from structural changes in the eyelid, they produce different patterns of symptoms. Ectropion primarily causes dryness and tearing from exposure, while entropion causes mechanical irritation from lashes scraping the eye surface. In some patients, the same underlying eyelid laxity can lead to either condition, and occasionally both may develop in different eyelids of the same person. Accurate diagnosis by our oculoplastic surgeon is essential because the surgical approach differs for each condition.
Causes and Risk Factors
The most common cause of both ectropion and entropion is involutional change, meaning the natural aging process weakens the tendons, muscles, and connective tissue that support the eyelid. Involutional ectropion accounts for 80 to 90 percent of all ectropion cases (PMC, 2025). As horizontal eyelid laxity increases with age, the lower lid may sag outward or, if the lower eyelid retractors become detached, the lid may roll inward instead. Patients who also have excess upper eyelid skin, known as dermatochalasis, may experience overlapping eyelid concerns that benefit from a comprehensive evaluation.
Scarring of the inner or outer eyelid surface can physically pull the lid out of alignment. Cicatricial ectropion may result from previous surgery, burns, trauma, or chronic skin conditions that contract the outer layer of the eyelid. Cicatricial entropion develops when scarring on the inner eyelid surface, sometimes caused by chemical burns, chronic inflammatory conditions, or infections such as trachoma, pulls the eyelid margin inward. Some patients with a history of eyelid cancer removal may develop cicatricial changes that require reconstructive correction.
Facial nerve paralysis, such as that caused by Bell palsy, reduces the tone of the orbicularis oculi muscle that normally helps close the eyelid and hold it against the eye. When this muscle cannot contract properly, the lower eyelid may fall away from the globe, resulting in paralytic ectropion. In contrast, spastic entropion occurs when a cycle of eye irritation and forceful squeezing of the eyelid muscles causes the eyelid to turn inward acutely, often following intraocular surgery or alongside existing ocular surface irritation.
In rare cases, a child is born with ectropion or entropion due to abnormal development of the eyelid structures. Congenital entropion is uncommon in people of European descent but is seen more frequently in certain Asian populations. Congenital ectropion may be associated with other eyelid or facial developmental differences. These cases are evaluated carefully to determine whether early surgical intervention is appropriate.
Diagnosis and Evaluation
Diagnosis begins with a careful clinical examination by our oculoplastic surgeon, who observes the resting position of the eyelid margin and assesses the overall tone and structure of the eyelid. We perform a snap-back test, in which the lower lid is gently pulled away from the eye and released to assess how quickly it returns to its normal position. A distraction test measures how far the eyelid can be pulled from the globe. These assessments help us determine the degree of eyelid laxity and guide our treatment recommendations.
We also examine the cornea with a slit lamp to check for abrasions, punctate erosions, or early scarring caused by the eyelid malposition. This step is especially important in entropion, where the lashes may have been rubbing against the cornea for an extended period. Identifying corneal involvement helps us determine the urgency of treatment and whether protective measures are needed before surgery.
Identifying whether the condition is involutional, cicatricial, paralytic, or spastic is essential for choosing the right surgical approach. Each type has a distinct mechanism, and the repair technique must address the specific anatomical problem. For example, a patient with paralytic ectropion requires a different strategy than a patient whose ectropion results from age-related tissue laxity. Our oculoplastic surgeon tailors every treatment plan to the individual cause and severity of the malposition.
Treatment Options
Preservative-free artificial tears, lubricating gels, and nighttime ointments help keep the cornea moist and reduce irritation for both conditions. For entropion, taping the lower eyelid downward can temporarily prevent the lid from rolling inward. Botulinum toxin injections may relax an overactive orbicularis muscle in spastic entropion, providing short-term relief while the underlying cause resolves. These measures are valuable for symptom management but are generally not permanent solutions.
The most common procedure for involutional ectropion is the lateral tarsal strip, which tightens the lower eyelid horizontally by shortening and reattaching the lateral canthal tendon to the orbital rim. This restores proper eyelid tension against the eye. If scarring has shortened the outer eyelid skin, a skin graft or flap may be required to release the tissue and allow the eyelid to return to a normal position. Surgery is typically performed under local anesthesia with light sedation in an outpatient setting, and published studies report successful outcomes in 90 to 95 percent of cases (Clinical studies, 2025).
Involutional entropion repair addresses the three main contributing factors: horizontal lid laxity, lower eyelid retractor weakness, and orbicularis muscle override. A lateral tarsal strip procedure corrects horizontal laxity, while retractor reinsertion tightens the tissue that pulls the eyelid margin downward and outward. In some cases, a small amount of orbicularis muscle is removed to prevent the muscle fibers from riding over the tarsal plate. Patients with ptosis (droopy eyelid) or other eyelid concerns may benefit from addressing multiple conditions in one procedure.
Most patients experience mild bruising and swelling for one to two weeks after eyelid surgery. Cold compresses, head elevation, and prescribed lubricating drops help manage discomfort during the early healing period. Sutures are typically removed within seven to fourteen days. Many patients notice immediate relief from the irritation or tearing that prompted surgery, even before the swelling fully resolves, and we schedule follow-up visits to monitor healing and confirm that the eyelid has settled into its corrected position.
Frequently Asked Questions
Complications are uncommon but can include mild bruising, temporary swelling, asymmetry, or minor wound-healing issues. In a small percentage of cases, the eyelid may not achieve the ideal position and a revision procedure may be needed. Serious complications such as infection or damage to the eye are rare when the surgery is performed by a fellowship-trained oculoplastic surgeon.
Most insurance plans, including Medicare, cover ectropion and entropion surgery when there is documented evidence of symptoms such as corneal damage, chronic irritation, or impaired eyelid function. We obtain the necessary clinical documentation and, when required, submit prior authorization on your behalf to help confirm coverage before your procedure.
Surgical correction is designed to be long-lasting, and most patients enjoy stable results for many years. However, because the tissues continue to age, there is a 5 to 15 percent chance that entropion may recur over time, and some patients may require a revision procedure. Cicatricial forms can recur if the underlying scarring process is not fully resolved.
Most patients return to light daily activities within a few days and resume work within one to two weeks, depending on the nature of their job. Strenuous exercise, heavy lifting, and swimming should be avoided for at least two to three weeks to allow the tissues to heal properly. We provide detailed aftercare instructions tailored to your specific procedure.
It is possible to have ectropion in one eyelid and entropion in another, particularly when generalized eyelid laxity is the underlying issue. Each eyelid is evaluated independently, and our oculoplastic surgeon can address multiple eyelid malpositions during a single surgical session when appropriate. This combined approach can reduce overall recovery time and improve comfort more efficiently.
Untreated ectropion can lead to chronic dryness, thickening of the exposed conjunctival tissue, and corneal damage from prolonged exposure. Untreated entropion poses an even greater risk because the constant rubbing of eyelashes against the cornea can cause abrasions, scarring, and infection that may permanently affect your vision. Seeking evaluation when symptoms first appear gives you the best opportunity for a successful outcome.
