What Causes Entropion

What causes entropion

Have you ever wondered what causes your eyelid to turn inward, causing discomfort and blurry vision? The answer lies in the condition known as entropion. This seemingly harmless yet bothersome condition occurs when your lower eyelid decides to play a game of hide-and-seek with your eyeball. But what exactly triggers this peculiar behavior? Stay tuned as we delve into the intriguing causes of entropion, uncovering the factors that contribute to this perplexing eye condition.

Overview and Symptoms

Entropion is a condition where the lower eyelid turns inward, causing discomfort, irritation, and vision problems. It is important to understand the overview and symptoms of entropion to effectively manage and treat the condition. The primary symptom of entropion is a feeling like there’s something in the eye, along with redness, tearing, blurry vision, and eye pain. The main cause of entropion is lower eyelid looseness, which can occur due to scarring, aging, eye injury, infection, or previous surgery. If left untreated, entropion can have long-term implications, including corneal irritation and injury, which can lead to permanent vision loss.

To manage entropion symptoms, non-surgical treatments can be considered. Lubricating eye drops and ointments provide temporary relief and protect the cornea. However, these treatments do not provide a permanent solution. Surgical options are usually necessary for full correction of entropion. The type of surgery depends on the cause of entropion and the condition of the surrounding tissue. For age-related entropion, a small part of the lower eyelid may need to be removed to tighten tendons and muscles. In cases where scar tissue or previous surgeries are the cause, a mucous membrane graft using tissue from the mouth or nasal passages may be required. It is important to note that temporary swelling and bruising can be expected after surgery.

Causes of Entropion

The most common cause of entropion is muscle weakness, which occurs when the muscles under the eyes weaken and the tendons stretch with age. This weakening of the muscles and stretching of the tendons can lead to the lower eyelid turning inward, causing the eyelashes to rub against the eyeball. Another cause of entropion is scarring and previous surgeries that can distort the normal curve of the eyelid, resulting in the eyelid turning inward. In some cases, entropion can be caused by a trachoma infection, which is a common eye infection in developing countries. This infection can lead to scarring of the inner eyelid and ultimately result in entropion. Eye irritation and inflammation can also contribute to entropion, as they can cause a spasm of the eyelid muscles and cause the lid to roll inward. Additionally, congenital entropion, which is present at birth, can be caused by an extra fold of skin on the eyelid. Understanding the causes of entropion is crucial in determining the appropriate treatment and preventing further complications.

Risk Factors

As you explore the risk factors for entropion, it is important to understand the factors that can increase your likelihood of developing this condition. Here are the key risk factors to consider:

  1. Age: Entropion is more common in older individuals, with the likelihood of developing the condition increasing with age.
  2. Previous burns or trauma on the face: Scar tissue formation from previous burns or trauma can distort the normal curve of the eyelid, increasing the risk of entropion.
  3. History of trachoma infection: Individuals who have had trachoma, a common eye infection in developing countries, are more susceptible to developing entropion due to scarring of the inner eyelid.
  4. Eye irritation or inflammation: People with chronic eye irritation or inflammation are at a higher risk of developing spastic entropion, where the eyelid muscles go into spasm and roll inward.

Complications of entropion can include corneal irritation, injury, and eye infections. If left untreated, it can lead to permanent vision loss. Diagnosis of entropion usually involves a routine eye exam, and treatment options range from nonsurgical alternatives such as eye drops and soft contact lenses to surgical procedures like eyelid repair. It is important to consult with an ophthalmologist to determine the best course of action for your specific case of entropion.


Untreated complications of entropion can lead to permanent vision loss, making it crucial to address the condition promptly. Entropion can cause various complications that can significantly impact vision. The table below outlines the complications, treatment options, diagnosis methods, surgical procedures, and the importance of early intervention in managing entropion.

Early intervention is essential in managing entropion to prevent complications and preserve vision. Prompt diagnosis through routine eye exams and physical examinations can facilitate timely treatment. Treatment options range from nonsurgical interventions such as eye drops and contact lenses to surgical procedures like lid tightening or mucous membrane grafts. Addressing entropion promptly can prevent corneal irritation, eye infections, and potential vision loss. It is important to consult with a healthcare professional to determine the most appropriate treatment plan based on the underlying cause of entropion and the severity of the condition.


To prevent complications and preserve vision, it is important to take proactive measures in managing entropion. By following these protective measures, you can reduce the risk of developing entropion and ensure early intervention if needed:

  1. Regular Eye Exams: Schedule regular eye exams with an ophthalmologist to detect any signs of entropion early on. This allows for prompt treatment and reduces the risk of complications.
  2. Eye Protection: Avoid activities that can cause eye trauma or injury, such as contact sports without proper eye protection. Wearing goggles or safety glasses can help prevent eye damage and reduce the risk of developing entropion.
  3. Proper Eye Hygiene: Practice good eye hygiene by keeping your eyes clean and free from irritants. Avoid rubbing your eyes excessively, as this can lead to eyelid irritation and potentially contribute to the development of entropion.
  4. Prompt Medical Attention: If you experience any symptoms of entropion, such as eye discomfort, redness, or blurry vision, seek medical attention promptly. Early intervention can prevent further damage and help preserve your vision.

Comparison With Ectropion

Ectropion, the outward-turning eyelid, is a condition that differs from entropion, the inward-turning eyelid. While both conditions can cause eye discomfort and irritation, they are distinct in their presentation and treatment options.

The causes of entropion differ from those of ectropion. Entropion is commonly caused by muscle weakness and tendon stretching with age. Scarring from previous surgeries or injuries can also lead to entropion. Additionally, trachoma, an eye infection common in developing countries, can cause scarring of the inner eyelid and result in entropion. On the other hand, ectropion is often caused by weakening of the muscles and tendons that hold the eyelid in place, which can be a result of aging or facial nerve palsy.

When it comes to treatment options, both entropion and ectropion have surgical and non-surgical therapies available. Non-surgical therapies for entropion include the use of eye drops, soft contact lenses, tape or stitches, and Botox injections to temporarily ease symptoms and turn the eyelid outward. However, surgery is usually necessary for permanent correction. The type of surgery depends on the cause of entropion and may involve tightening tendons and muscles or using tissue grafts.

In comparison, ectropion can often be managed with non-surgical approaches such as lubricating eye drops and ointments to protect the cornea. However, if these measures are insufficient, surgery may be required to tighten the eyelid and restore its normal position.
