Yes
Overview
Ectropion is an outward turning of the eyelid margin, most commonly involving the lower eyelid. The condition causes poor eyelid apposition, tear film instability, and exposure of the ocular surface, leading to irritation and chronic tearing. Ectropion may be involutional, paralytic, cicatricial, congenital, or mechanical.
Symptoms & Signs
- Excessive tearing (epiphora)
- Dry eye symptoms
- Foreign body sensation
- Redness and irritation
- Exposure keratopathy
- Visible outward eyelid turning
Common Causes
- Age-related eyelid laxity
- Facial nerve palsy
- Cicatricial scarring
- Trauma or burns
- Eyelid tumors
- Congenital abnormalities
Diagnosis
- External eyelid examination
- Slit-lamp examination
- Eyelid distraction and snap-back tests
- Assessment of punctal position
- Evaluation for corneal staining
Differential Diagnosis
| Condition | Distinguishing Feature |
|---|---|
| Entropion | Inward turning eyelid |
| Facial nerve palsy | Underlying cause of paralytic ectropion |
| Trichiasis | Misdirected lashes with normal lid position |
| Dermatochalasis | Excess eyelid skin without lid eversion |
Treatment
- Artificial tears and lubricating ointment
- Moisture chamber or nighttime taping
- Treat the underlying cause
- Temporary punctal plugs in selected patients
- Surgical eyelid tightening or reconstruction
Complications
- Exposure keratopathy
- Corneal ulceration
- Chronic conjunctivitis
- Permanent vision loss if severe
Common ICD-10 Codes
| Code | Description |
|---|---|
| H02.102 | Ectropion, right lower eyelid |
| H02.105 | Ectropion, left lower eyelid |
| H02.101 | Ectropion, right upper eyelid |
| H02.104 | Ectropion, left upper eyelid |
Frequently Asked Questions
Can ectropion be treated without surgery?
Lubrication and eyelid taping can temporarily relieve symptoms, but most involutional cases require surgery for lasting correction.
Why does ectropion cause excessive tearing?
The eyelid no longer properly contacts the eye, preventing normal tear drainage and causing reflex tearing.
