A comprehensive overview of lagophthalmos, including causes, symptoms, diagnosis, treatment, and complications.
Eyelid Disorder
H02.20โH02.209
Acquired or Congenital
Yes
Overview
Lagophthalmos is the inability to completely close the eyelids. It commonly results from facial nerve dysfunction, eyelid trauma, scarring, thyroid eye disease, or postoperative changes. Incomplete eyelid closure can lead to exposure keratopathy and corneal injury.
Symptoms & Signs
- Incomplete eyelid closure
- Dry eye symptoms
- Foreign body sensation
- Redness
- Blurred vision
- Exposure keratopathy
- Nocturnal eye irritation
Common Causes
- Bell’s palsy
- Facial nerve paralysis
- Thyroid eye disease
- Eyelid trauma
- Cicatricial eyelid changes
- Postoperative eyelid surgery
Diagnosis
- External eyelid examination
- Assessment of blink and eyelid closure
- Slit-lamp examination
- Fluorescein staining
- Corneal sensation when indicated
Differential Diagnosis
| Condition | Distinguishing Feature |
|---|---|
| Facial nerve palsy | Underlying neurologic cause |
| Ectropion | Outward lid turning |
| Exposure keratopathy | Corneal complication |
| Ptosis | Drooping upper lid |
Treatment
- Frequent preservative-free artificial tears
- Lubricating ointment at bedtime
- Nighttime eyelid taping or moisture chamber
- Bandage contact lens or scleral lens in selected cases
- Gold-weight implantation or eyelid surgery for persistent cases
Complications
- Exposure keratopathy
- Corneal ulcer
- Corneal scarring
- Permanent vision loss
Common ICD-10 Codes
| Code | Description |
|---|---|
| H02.203 | Lagophthalmos, bilateral |
| H02.206 | Lagophthalmos, unspecified eye |
| G51.0 | Bell’s palsy (common cause) |
Frequently Asked Questions
Can lagophthalmos damage vision?
Yes. Chronic exposure of the cornea can lead to ulceration, scarring, infection, and permanent vision loss if not treated.
Is surgery always necessary?
No. Mild cases often respond to lubrication and eyelid protection, while persistent or severe cases may require surgical intervention.
