Differential diagnosis (1)  

  • Preseptal cellulitis  

  • Eyelid haematoma  

  • Acute dacryocystitis  

  • Chalazion (Meibomian gland obstruction with cyst formation)  

  • Sebaceous gland carcinoma  


Possible management by optometrist 

Advice (1)  

  • Most hordeola resolve spontaneously or discharge, followed by resolution  

  • For external hordeolum, removal of the associated eyelash may aid resolution   

  • Apply warm compresses (approximately 40–45 °C for up to 10 minutes, several times daily) to promote drainage and relieve symptoms   

  • Identify and manage associated blepharitis or ocular rosacea  

  • Advise the patient to return if symptoms persist or worsen  

  • In cases that do not spontaneously discharge (more common with internal hordeola), referral for incision may be considered  

Treatment 

  • Topical antibiotics (e.g. chloramphenicol) may be considered where there is copious mucopurulent discharge (1)  

  • In more severe cases not responding to topical treatment, consider systemic broad‑spectrum antibiotics (1) (e.g. Flucloxacillin or Co-amoxiclav (1); use Doxycycline if allergy to Penicillin exists (7))

  • In selected severe symptomatic cases, a short course of topical corticosteroid (e.g. fluorometholone) may be considered (1)


Typical dosage/duration 

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

  • Chloramphenicol 0.5% eye drops (1,5) (POM): One drop every 2 (waking (7)) hours for 48 hours. After this period, treatment should be every 4 hours during waking hours. Eye drops may be supplemented by 1% ointment at night. The course of treatment should be 5 days (even if symptoms improve) (2,3)  

  • Chloramphenicol 1% eye ointment (1,5) (POM): Apply at night (if eye drops used during the day), alternatively apply 3–4 times daily, if ointment used alone. The course of treatment should be 5 days (even if symptoms improve) (2,3)  

  • Flucloxacillin 500mg oral capsules (6) (POM): 500mg 4 times daily for 5-7 days (6)  

  • Co-amoxiclav oral capsules (6) (POM): 500mg/125mg 1 capsule 3 times daily for 7 days (6)   

  • Doxycycline 100mg oral tablets/capsules (5)(POM): 200mg in one dose on the first day then 100mg once daily for 5-7 days (in more serious infections can increase to 100mg twice daily for duration of treatment) (6)  

  • Fluorometholone (FML) 0.1% eye drops (1,5) (POM): One drop (7), two to four times daily. For more serious conditions apply every 1 hour for 24-48 hours, then reduce to two to four times daily (2,3). Duration will depend on severity of the condition (6)  

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 

  • Treatment may be provided within available locally enhanced schemes, or by community IP optometrists/OMPs, as appropriate (7)  

  • Normally no referral required (1)  


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

  • See Further management options (7)  

  • Incision and drainage may be performed where appropriate (1)  

  • Surgical intervention is rare during the acute infective stage (1)
