OP2.1 | Common Lid Disorders: Aetiology, Features and Treatment — SDL Guide (Part 3)

Management of Common Lid Disorders

The management of common lid disorders follows a principle of graduated intervention: conservative measures first, surgical correction for definitive treatment of structural anomalies, and antibiotic therapy for infections. Understanding the indication and timing of surgery versus medical management is essential for the final-year student, who must triage patients appropriately in a resource-limited setting.

Hordeolum externum and internum: First-line is warm compresses 3–4 times daily for 5–10 minutes, which liquefies the inspissated secretion and promotes spontaneous pointing and drainage. Topical antibiotic ointment (chloramphenicol 1% four times daily) reduces secondary lid-margin colonisation. Systemic antibiotics (oral flucloxacillin or co-amoxiclav) are reserved for hordeolum with preseptal spread. If pointing has not occurred within 2 weeks, incision and drainage under local anaesthesia is performed: externum is incised vertically through the skin; internum is incised through the palpebral conjunctiva horizontally along the meibomian gland orientation. Intralesional triamcinolone injection (0.05–0.1 mL of 10 mg/mL) can be used for a chronic internal hordeolum that has converted to a chalazion.

Blepharitis: As covered above — long-term lid hygiene is the cornerstone. The analogy is 'blepharitis is like dandruff of the eyelids — you can control it but not cure it.' Warm compresses melt meibomian caps; lid scrubs remove biofilm and crust; topical chloramphenicol ointment for staphylococcal type; oral doxycycline 100 mg daily for MGD (6–12 weeks). Lubricants for evaporative dry eye.

Ectropion: Medial ectropion in older patients may be managed with lateral tarsal strip surgery (tightening the lower lid horizontally). Cicatricial ectropion may require skin grafting. Paralytic ectropion is first managed conservatively (lubricants, taping the lid at night) while facial nerve recovery is awaited; gold weight implant to the upper lid or lower lid tightening may be needed for permanent palsy.

Entropion: Involutional entropion — botulinum toxin injection to the orbicularis can provide temporary relief; definitive repair is lower lid retractor advancement (Wies procedure) combined with horizontal lid tightening. Cicatricial entropion (e.g., trachoma) — posterior lamellar mucous membrane grafting (hard palate or buccal mucosa) is required when there is significant conjunctival scarring.

Lagophthalmos: Artificial tears during the day, lubricating ointment at night, moisture chambers (spectacles with side shields) for exposure protection. Treat the underlying cause. For permanent facial nerve palsy, gold weight implant (inserted under the upper lid skin to aid gravitational closure) has replaced tarsorrhaphy as the preferred procedure at most centres because it preserves the cosmetic opening of the eye.

Preseptal cellulitis: Oral antibiotics (co-amoxiclav 625 mg TDS, 5–7 days) with warm compresses; treat any primary source (infected hordeolum, dacryocystitis). Admit and give IV antibiotics (IV co-amoxiclav 1.2 g TDS) if: child under 1 year, systemically unwell, not improving after 24–48 hours of orals, or if diagnosis is uncertain.

Self-Assessment: Common Lid Disorders

Self-assessment questions for common lid disorders consolidate clinical reasoning by requiring you to integrate aetiology, examination findings, and management decisions rather than recall isolated facts. The NMC CBME framework for ophthalmology expects that a graduating doctor can differentiate the common lid conditions encountered in primary care — hordeolum, chalazion, blepharitis, positional anomalies, and preseptal cellulitis — and initiate appropriate first-line treatment. The danger in lid disorders lies in missing the progression from preseptal to orbital cellulitis: a swollen lid with restricted painful eye movement demands urgent CT and systemic antibiotics, not reassurance. Similarly, a painless, chronically recurrent chalazion in an elderly patient should raise the suspicion of a sebaceous gland carcinoma masquerading as benign lid pathology — biopsy before steroid injection in uncertain cases. This review section mirrors the standard question formats used in university examinations and clinical OSCEs.

1. A 30-year-old presents with a painful, red swelling at the lid margin for two days. On examination, there is a yellow pustule at a lash follicle. What is the diagnosis, which gland is involved, and what is the first-line treatment?
2. A 55-year-old has a non-tender, firm nodule in the upper lid for six weeks. There is no overlying skin erythema and the lid margin is normal. What is the most likely diagnosis and how does it differ from a hordeolum?
3. Describe the four signs of anterior blepharitis. What organism is most commonly responsible and what topical treatment is effective?
4. A 70-year-old has persistent watering, foreign body sensation, and corneal punctate erosions. On pulling the lower lid down, the lid springs back inward. What is the diagnosis and what surgical options exist?
5. What distinguishes preseptal from orbital cellulitis clinically? Name two features on examination that indicate postseptal spread and mandate urgent CT and IV antibiotics.

Expected answers: (1) Hordeolum externum (stye) — Zeis or Moll gland — hot compresses ± topical antibiotic. (2) Chalazion — Meibomian gland lipogranuloma, chronic, non-tender, no lash involvement. (3) Collarettes at lash bases, scaling, lid margin hyperaemia, loss of lashes (madarosis) — Staphylococcus aureus — lid scrubs + fusidic acid. (4) Entropion — options: everting sutures, Wies procedure, lower lid retractor reinsertion, Quickert sutures. (5) Proptosis and painful/restricted eye movements — CT orbit + admission for IV antibiotics (e.g., co-amoxiclav or piperacillin-tazobactam).
