Date of last review:

29/4/2026

Date of next review:

29/4/2028

Date of publication:

6/7/2026

Differential Diagnosis ⁽¹⁾

Eyelidretraction (e.g. Graves’ disease)
- lashes appear hidden due to retracted lid fold
Distichiasis
- extra congenital row of lashes from meibomian gland orifices
Trichiasis
- normally positioned lashes misdirected toward the cornea, typically from inflammation
Dermatochalasis
- redundant eyelid skin causing misdirected lashes, common in older adults
Epiblepharon
- congenital horizontal skin fold causing vertical lash misdirection; often asymptomatic and resolves with age

Possible management by optometrist

Advice ⁽¹⁾

Lid taping to the cheek to rotate the lid/lashes away from the globe
- useful in involutional or spastic entropion
Epilation for localised trichiasis (e.g. cicatricial entropion)
Therapeutic (bandage) contact lens to protect the cornea from lash abrasion

Treatment

Ocular lubricants for tear deficiency/instability related symptoms (drops for use during the day, unmedicated ointment for use at bedtime)⁽¹⁾. Refer to local formularies for suitable options ⁽⁶⁾

NB. Patients with long-term topical medication use may develop sensitivity to preservatives or active ingredients — switch to unpreserved preparations where appropriate ⁽¹⁾

Typical adult dosage/duration

(Blue text = IP, black text = non-IP)

As required (see ‘Treatment’ above)

Regimens should be adjusted according to severity and patient factors (e.g. age, weight, pregnancy, renal function). Prescribing should follow local formulary and national guidance where available ⁽⁷⁾.

In cases of known sensitivities, please consult local formularies for alternative options ⁽⁷⁾.

Further management options ⁽¹⁾

Routine referral after initial optometric management is standard
Urgent referral is required if:
- Congenital entropion
- Any sight threatening corneal involvement

Possible management in secondary care or local/community pathways where available ⁽¹⁾

Surgical Management

Surgery provides definitive treatment for all entropion types; procedure selection depends on underlying cause(s)

Indications for Surgery

Persistent symptoms
Recurrent bacterial conjunctivitis
Reflex tear hypersecretion
Persistent epiphora
Superficial keratopathy
Risk of ulceration or microbial keratitis

Evidence Supported Approaches

Combined horizontal and vertical eyelid tightening is effective for involutional entropion
Botulinum toxin injections may provide temporary relief in spastic entropion
