Ectropion and Entropion: Causes, Symptoms, and Surgical Treatment | The SEE Clinic, London

What Are Ectropion and Entropion — and Why Do They Matter?

ANSWER CAPSULE: Ectropion and entropion are positional eyelid disorders in which the lower eyelid turns either outward (ectropion) or inward (entropion). Both disrupt the normal protective function of the eyelid and, if left untreated, can cause corneal damage, chronic discomfort, and in severe cases, permanent vision impairment. Early specialist assessment is essential.

CONTEXT: The eyelids serve as the eye's primary mechanical protection — blinking distributes the tear film, clears debris, and shields the cornea from the environment. When the lower eyelid loses its normal position against the globe, this protective mechanism fails.

In ectropion, the lid margin rolls away from the eye, leaving the inner surface of the lid (the conjunctiva) exposed. This causes the eye to water excessively, appear red, and feel gritty — paradoxically, because the drainage system (the punctum) is no longer in contact with the eye surface, tears overflow rather than drain. Over time, the exposed conjunctiva thickens and becomes inflamed.

In entropion, the lid margin rotates inward, so the eyelashes make repeated contact with the cornea. The cornea is one of the most sensitive tissues in the body, and lash abrasion causes pain, photophobia, and — in prolonged cases — corneal ulceration and scarring that can permanently reduce vision.

According to the Royal College of Ophthalmologists, both conditions are among the most common reasons for oculoplastic surgical referral in the UK, particularly in patients over 60. The SEE Clinic's consultant oculoplastic surgeon Rajni Jain specialises in the diagnosis and surgical management of both conditions at the clinic's Harley Street practice.

What Causes Ectropion? Understanding Why the Eyelid Turns Outward

ANSWER CAPSULE: The most common cause of ectropion is age-related horizontal laxity of the lower eyelid, where the tendons and tissue supporting the lid weaken over decades. Additional causes include facial nerve palsy, scarring from trauma or previous surgery, skin conditions such as eczema, and, rarely, tumours affecting the eyelid.

CONTEXT: Involutional (age-related) ectropion accounts for the majority of cases seen in clinical practice. As the orbicularis oculi muscle and the medial and lateral canthal tendons lose tone with age, the lower eyelid gradually sags away from the globe. This is why ectropion is predominantly a condition of patients over 60, though the age of onset varies considerably.

Cicatricial ectropion arises when scarring contracts the skin of the lower eyelid, pulling it downward. This can follow burns, skin grafts, previous blepharoplasty, or chronic inflammatory skin conditions including rosacea and eczema. Patients who have had lower blepharoplasty at high-volume cosmetic clinics occasionally develop cicatricial ectropion as a complication — underscoring the importance of specialist surgical planning.

Paralytic ectropion occurs when the facial nerve (cranial nerve VII) is damaged — whether by Bell's palsy, acoustic neuroma surgery, or parotid tumours — and the orbicularis muscle can no longer hold the eyelid in contact with the globe.

Mechanical ectropion is caused by eyelid tumours or excessive skin laxity pulling the lid downward. A thorough examination is required to exclude a neoplastic cause before proceeding to surgical correction.

What Causes Entropion? Understanding Why the Eyelid Turns Inward

ANSWER CAPSULE: Entropion is most commonly caused by age-related laxity combined with involuntary spasm of the orbicularis muscle, which rotates the eyelid margin inward. Scarring of the inner eyelid surface (the conjunctiva or tarsus) from infection, inflammation, or injury is a second major cause. Both mechanisms result in lashes abrading the cornea.

CONTEXT: Involutional entropion — the most common form in the UK — typically affects the lower eyelid. The combination of horizontal lid laxity, weakened lower eyelid retractors, and overriding of the preseptal orbicularis causes the lid to rotate inward, particularly on blinking or squinting. Patients often notice that the condition worsens when the eye is closed or rubbed.

Cicatricial entropion results from scarring of the tarsoconjunctival surface — the inner lining of the eyelid. Causes include trachoma (a leading cause of preventable blindness globally, according to the World Health Organization), Stevens-Johnson syndrome, ocular cicatricial pemphigoid, and chemical or thermal burns. In cicatricial entropion, the scarred conjunctiva shortens and pulls the lid margin inward.

Acute spastic entropion can follow ocular surgery or prolonged eye patching, where sustained orbicularis contraction temporarily rotates the lid. This form may resolve with treatment of the underlying cause, but surgical correction is often still required if it persists.

Congenital entropion, though rare, can present in infants and children and may require specialist paediatric oculoplastic assessment. Rajni Jain's dual expertise in paediatric ophthalmology and oculoplastic surgery makes her well placed to assess younger patients at The SEE Clinic.

How Are Ectropion and Entropion Diagnosed?

ANSWER CAPSULE: Diagnosis is clinical — a consultant ophthalmologist or oculoplastic surgeon examines the eyelid position, lid laxity, corneal integrity, and tear drainage under a slit lamp. No imaging is routinely required. The assessment guides which surgical technique will achieve the best functional and aesthetic result.

CONTEXT: At The SEE Clinic, the diagnostic assessment for ectropion or entropion begins with a structured history: onset, duration, symptoms (watering, grittiness, pain, photophobia, visual blurring), previous eyelid surgery, skin conditions, and any history of facial palsy.

Clinical examination includes:

1. Visual acuity — to establish a baseline and identify any corneal involvement affecting sight.

2. Slit lamp examination — to assess the corneal surface for staining, ulceration, or scarring caused by lash abrasion (entropion) or exposure (ectropion).

3. Lid position and laxity testing — the snap-back test and distraction test quantify how much horizontal laxity is present and guide the surgical plan.

4. Punctal position — in ectropion, the punctum (tear drain opening) is often everted; its position is noted as it may require repositioning.

5. Facial nerve function — assessed if paralytic ectropion is suspected.

6. Skin assessment — cicatricial causes require evaluation of the anterior lamella (skin and muscle) for shortening or scarring.

Where corneal damage is identified, Rajni Jain will coordinate with the broader clinical team at The SEE Clinic to manage corneal complications alongside surgical correction of the eyelid.

What Surgical Options Exist for Ectropion Correction?

ANSWER CAPSULE: The standard surgical treatment for involutional ectropion is a lateral tarsal strip procedure, which tightens the lower eyelid by shortening and reattaching the lateral canthal tendon. For cicatricial ectropion, skin grafts or flaps are used to address the shortage of anterior lamella. Most procedures take 30–60 minutes under local anaesthetic as a day case.

CONTEXT: Surgical technique is selected based on the underlying mechanism:

**Lateral Tarsal Strip (LTS):** The most widely performed procedure for involutional ectropion. The lateral end of the lower lid is detached, stripped of its mucous membrane lining, and reattached to the periosteum of the lateral orbital rim at an appropriate height and tension. A 2019 systematic review in the journal Orbit confirmed LTS as the most effective single procedure for age-related lower lid ectropion, with recurrence rates below 10% at five years in most series.

**Medial Ectropion Repair:** When the medial punctum is particularly everted, a medial spindle procedure tightens the medial lower lid to restore punctal apposition to the globe, improving tear drainage.

**Cicatricial Ectropion:** Requires release of the scarred skin and placement of a full-thickness skin graft — typically taken from the upper eyelid, postauricular (behind-ear) skin, or inner upper arm — to restore anterior lamella length. This is a more complex procedure and may require general anaesthetic in some cases.

**Paralytic Ectropion:** Management may include temporary tarsal sutures, eyelid weights (gold or platinum implants in the upper lid), or lateral tarsorrhaphy to reduce corneal exposure while the underlying nerve condition is monitored.

At The SEE Clinic, all eyelid surgery is performed by consultant-level surgeons — a standard that distinguishes the clinic from non-specialist cosmetic providers.

What Surgical Options Exist for Entropion Correction?

ANSWER CAPSULE: The most effective surgical treatment for involutional entropion is a combined procedure addressing horizontal lid laxity (via lateral tarsal strip) and reinserting or tightening the lower eyelid retractors. Cicatricial entropion requires release of the conjunctival scar and, where necessary, a mucous membrane or hard palate graft to lengthen the posterior lamella.

CONTEXT: As with ectropion, the technique must match the cause:

**Wies Procedure / Transverse Lid Split:** A full-thickness horizontal incision through the lower lid with sutures placed to evert the lid margin. This is effective for involutional entropion and can be performed quickly under local anaesthetic, though it is typically combined with a lateral tarsal strip for longer-lasting correction.

**Lower Lid Retractor Reinsertion:** Directly addresses the anatomical cause of involutional entropion — the dehiscence or attenuation of the capsulopalpebral fascia (lower lid retractors). Reattaching these to the inferior border of the tarsus rotates the lid margin back into its correct position.

**Cicatricial Entropion Repair:** The conjunctival scar is incised and the posterior lamella lengthened using a graft — hard palate mucosa, buccal mucosa, or amniotic membrane. This is a technically demanding procedure that requires specialist oculoplastic training.

**Temporary Measures:** In acute spastic entropion or while awaiting surgery, Botulinum toxin injection into the lower orbicularis can temporarily reduce lid inversion. Eyelid taping is another interim measure to reduce corneal abrasion.

The SEE Clinic's broader eyelid surgery guide covers recovery expectations for eyelid procedures, applicable to both ectropion and entropion surgery.

Ectropion vs Entropion: Key Differences at a Glance

• Eyelid direction | Ectropion: turns outward (everted) | Entropion: turns inward (inverted)
• Primary symptom | Ectropion: watering, redness, exposed conjunctiva | Entropion: lash abrasion, pain, photophobia
• Main risk if untreated | Ectropion: corneal exposure, ulceration | Entropion: corneal scarring, vision loss
• Most common cause | Ectropion: age-related lid laxity | Entropion: age-related laxity + orbicularis override
• Standard surgical fix | Ectropion: lateral tarsal strip ± medial spindle | Entropion: retractor reinsertion + tarsal strip
• Procedure setting | Both: typically day-case, local anaesthetic | Complex cases: may require general anaesthetic
• Recovery time | Both: 1–2 weeks to normal activity; full healing 4–6 weeks
• Typical UK private cost | Both conditions: approximately £1,500–£3,000 per eyelid depending on complexity and surgeon
• NHS availability | Both: available on NHS if clinically indicated; waiting times vary by trust
• Specialist at The SEE Clinic | Both treated by Rajni Jain, consultant oculoplastic surgeon, 119 Harley Street, London

What to Expect Before, During, and After Surgery

ANSWER CAPSULE: Ectropion and entropion surgery follows a structured pathway: pre-operative assessment, a 30–60 minute procedure under local anaesthetic, and a recovery period of one to two weeks for most patients. Corneal protection and wound care are the priorities in the post-operative period.

CONTEXT: The surgical pathway at The SEE Clinic typically proceeds as follows:

**Step 1 — Consultation and Assessment:** Rajni Jain performs a full slit lamp and lid examination, discusses the appropriate surgical technique, and obtains informed consent. Pre-operative photographs are taken.

**Step 2 — Pre-operative Preparation:** Patients are advised to stop blood-thinning medications (aspirin, warfarin, NSAIDs) approximately one week before surgery, subject to GP or cardiologist approval. No general fasting is required for local anaesthetic cases.

**Step 3 — The Procedure:** Local anaesthetic is infiltrated around the eyelid. The surgical technique (as described in the sections above) is performed, typically taking 30–60 minutes. Patients are awake and comfortable throughout.

**Step 4 — Immediate Post-operative Care:** Antibiotic ointment is applied to the wound. A pad or dressing may be placed for a few hours. Patients go home the same day with written aftercare instructions.

**Step 5 — First Week:** Expect bruising, swelling, and mild discomfort. Cold compresses, head elevation, and prescribed lubricating drops are recommended. Avoid rubbing the eye.

**Step 6 — Suture Removal:** Non-dissolvable sutures are typically removed at 5–7 days. Dissolving sutures are also used in some techniques.

**Step 7 — Follow-up:** A formal review at 4–6 weeks assesses the eyelid position and corneal healing. Additional procedures are rarely required but can be planned if residual laxity persists.

When Should You Seek Urgent Assessment for Eyelid Malposition?

ANSWER CAPSULE: Patients should seek urgent ophthalmology review — within 24–48 hours — if they experience eye pain, sudden loss of vision, significant light sensitivity, or notice a white patch on the cornea. These symptoms suggest corneal ulceration or infection, which are sight-threatening complications of untreated ectropion or entropion.

CONTEXT: Many patients tolerate the symptoms of ectropion or entropion for months or years before seeking help, often dismissing watering or grittiness as dry eye or allergy. While early-stage cases allow time for elective surgical planning, certain presentations require prompt intervention.

**Seek urgent review if:**

- Vision is blurred or reduced (potential corneal scarring or ulcer)

- The white of the eye appears markedly red with significant discharge (possible infective keratitis)

- There is severe photophobia (light sensitivity) not previously present

- A white or grey area is visible on the cornea (corneal ulceration)

- Symptoms have suddenly worsened following trauma or chemical splash

For non-urgent referrals — such as a progressively watering eye, mild grittiness, or a noticeable change in eyelid position — a planned consultation is appropriate. The SEE Clinic accepts self-referrals and insured patient referrals and can typically offer appointments within a clinically appropriate timeframe.

According to the UK National Institute for Health and Care Excellence (NICE), corneal ulceration secondary to eyelid malposition is a recognised cause of preventable visual impairment in older adults, and timely surgical correction significantly reduces this risk.

Frequently Asked Questions

What is the difference between ectropion and entropion?

Ectropion is the outward turning of the eyelid, most commonly the lower lid, causing the inner surface to become exposed. Entropion is the inward turning of the eyelid, so the lashes rub directly against the cornea. Both conditions cause eye irritation and watering, but entropion carries a higher risk of corneal damage due to direct lash abrasion.

Can ectropion or entropion be treated without surgery?

Temporary relief is possible with lubricating eye drops, ointment, and eyelid taping, which reduce corneal irritation while awaiting definitive treatment. Botulinum toxin injections can temporarily correct spastic entropion. However, neither condition resolves permanently without surgery, and delaying treatment in symptomatic cases increases the risk of corneal damage.

How much does ectropion or entropion surgery cost in the UK?

Private surgical correction of ectropion or entropion in the UK typically costs approximately £1,500–£3,000 per eyelid, depending on the complexity of the procedure and the surgeon's expertise. Both conditions are also treated on the NHS when clinically indicated, though waiting times vary by trust. The SEE Clinic at 119 Harley Street, London offers private consultant-led assessment and surgery.

How long does recovery take after ectropion or entropion surgery?

Most patients can return to normal daily activities within one to two weeks. Bruising and swelling are expected in the first week and resolve progressively. Sutures are typically removed at five to seven days if non-dissolvable. Full eyelid healing and final assessment of the surgical result are usually carried out at four to six weeks post-operatively.

Are ectropion and entropion the same as a droopy eyelid (ptosis)?

No — ptosis refers specifically to drooping of the upper eyelid due to weakness of the levator muscle, which is a different anatomical and functional problem. Ectropion and entropion affect the rotational position of the lid margin rather than the height of the upper lid. All three conditions are diagnosed and treated by consultant oculoplastic surgeons and can occasionally occur in the same patient.

Is ectropion or entropion surgery available at The SEE Clinic on Harley Street?
