The facts most likely to be tested
A hordeolum is an acute focal infection, typically staphylococcal, of the eyelid glands.
An external hordeolum (stye) arises from an obstruction of the glands of Zeis or glands of Moll at the eyelash follicle.
An internal hordeolum results from an infection of the Meibomian gland located within the tarsal plate.
Clinical presentation features a painful, erythematous, tender nodule on the eyelid margin.
The primary initial management for a hordeolum is warm compresses applied to the affected area several times daily.
A chalazion is distinguished from a hordeolum by being a painless, chronic, lipogranulomatous inflammation of the Meibomian gland.
Topical antibiotic ointments are indicated only if the infection is associated with blepharitis or if the hordeolum fails to resolve with conservative measures.
Vignette unlocked
A 28-year-old male presents to the urgent care clinic complaining of a 2-day history of a painful, red bump on his left upper eyelid. On physical examination, there is a localized, tender, erythematous nodule at the eyelid margin near the base of the eyelashes. The surrounding conjunctiva is clear, and there is no evidence of vision changes or proptosis. The patient reports no history of trauma or similar lesions in the past.
What is the most appropriate initial management for this patient?
Warm compresses
The patient's presentation of a painful, tender nodule at the eyelid margin is classic for an external hordeolum, which is managed primarily with warm compresses to promote drainage.

Etiology / Epidemiology
Acute focal infection of eyelid glands, most commonly caused by Staphylococcus aureus.
Clinical Manifestations
Localized, painful, erythematous, tender nodule on the eyelid margin; hordeolum.
Diagnosis
Diagnosis is clinical; no laboratory or imaging studies are required.
Treatment
First-line is warm compresses; topical antibiotics are reserved for persistent cases.
Prognosis
Self-limiting condition; complications are rare but include preseptal cellulitis.

Epidemiology & Etiology
Common in all age groups, often associated with poor eyelid hygiene or blepharitis. Staphylococcus aureus is the primary pathogen in the vast majority of cases. Recurrence is common in patients with chronic inflammatory conditions.
Pertinent Anatomy
External hordeolum involves the glands of Zeis or Moll at the lid margin. Internal hordeolum involves the Meibomian glands located within the tarsal plate.
Pathophysiology
Obstruction of the gland duct leads to stasis and subsequent bacterial overgrowth. This triggers an acute inflammatory response, resulting in a localized abscess. The process is essentially a focal pyogenic infection of the eyelid.
Clinical Manifestations
Patients present with a painful, red, tender nodule on the eyelid. An external hordeolum points toward the lid margin, while an internal one may point toward the conjunctival surface. Red flags include vision changes, proptosis, or ophthalmoplegia, which suggest progression to orbital cellulitis.
Diagnosis
The diagnosis is clinical based on the presence of a tender, erythematous nodule. No gold standard diagnostic test exists. If the lesion is atypical or fails to resolve, biopsy may be considered to rule out sebaceous cell carcinoma.
Treatment
Initial management consists of warm compresses applied for 15 minutes, 4 times daily. Topical erythromycin or bacitracin ointment may be used if the infection is persistent. Do not attempt to drain the lesion, as this risks spreading the infection to the orbit.
Prognosis
Most lesions resolve spontaneously within 1-2 weeks. Preseptal cellulitis is the most significant complication requiring systemic antibiotics. If a nodule persists beyond 4 weeks, consider referral for incision and curettage.
Differential Diagnosis
Chalazion: painless, rubbery, chronic nodule
Preseptal cellulitis: diffuse eyelid edema and erythema
Dacryocystitis: inflammation of the lacrimal sac
Sebaceous cell carcinoma: persistent, recurrent, or non-healing lesion
Xanthelasma: yellow, lipid-laden plaques
