Yes, Stevens-Johnson Syndrome Frequently Affects the Eyes
Ocular involvement occurs in approximately 74% of SJS/TEN patients during the acute phase and represents a major cause of long-term morbidity, including severe visual impairment and blindness 1. This is not a minor or rare complication—eye involvement is one of the defining features of the disease and demands immediate ophthalmologic attention.
Acute Ocular Manifestations
The eyes are affected through inflammation of the mucosal surfaces, presenting with:
- Conjunctival hyperemia (mild involvement)
- Pseudomembrane formation on the conjunctiva
- Corneal and conjunctival epithelial defects
- Chemosis and conjunctivitis
- Eyelid involvement with potential skin sloughing
The severity is graded from 0 (no involvement) to 3 (very severe, with both epithelial defects and pseudomembrane formation) 1.
Distribution of Severity
Among patients with ocular involvement 1:
- 58% have mild involvement (eyelid edema, conjunctival injection)
- 8% have moderate involvement (membranous conjunctivitis, corneal defects)
- 8% have severe involvement (symblepharon, visual loss, nonhealing defects)
Critical Management Principle
The severity of acute ocular disease does NOT predict long-term complications—this is a crucial pitfall 1. Even patients with mild acute involvement can develop severe chronic sequelae. Therefore, all patients with SJS/TEN require ophthalmologic evaluation regardless of apparent severity, and long-term follow-up is mandatory.
Immediate Actions Required
Initial Assessment
Every patient with SJS/TEN must have ophthalmologic examination as part of initial assessment, followed by daily review during acute illness 1. Use fluorescein staining to assess epithelial loss on cornea and conjunctiva 2.
Acute Phase Treatment Protocol
Lubrication: Two-hourly application of nonpreserved hyaluronate or carmellose eye drops, started immediately 1
Daily ocular hygiene by ophthalmologist or trained nurse 2, 1:
- Gentle saline irrigation to remove mucous/debris
- Breakdown of conjunctival adhesions using squint hook and forceps
- Apply topical anesthetic (proparacaine/tetracaine) before procedure
- Never blindly sweep fornices with cotton buds—this causes damage 1
Corneal exposure prevention in unconscious/semiconscious patients 2, 1:
- Establish moisture chamber with polyethylene film
- Apply plastic wrap with thin ointment layer if significant eyelid sloughing
- Use long-lasting ophthalmic ointment
Infection prophylaxis: Broad-spectrum topical antibiotics (quinolones like moxifloxacin or levofloxacin four times daily) when corneal staining or ulceration present 1
Topical corticosteroids: Commonly used to ameliorate conjunctival inflammation, though use with caution if corneal epithelial defect present 1
Chronic Complications
Approximately 50-63% of patients with acute ocular involvement develop chronic complications 1, most commonly:
- Severe dry eye syndrome
- Trichiasis (misdirected eyelashes)
- Symblepharon (adhesions between eyelid and bulbar conjunctiva)
- Limbal stem cell deficiency
- Conjunctival fornix foreshortening
- Visual loss
These complications may not become apparent until late after the acute episode, necessitating long-term ophthalmologic follow-up 1.
Key Pitfalls to Avoid
Assuming mild acute disease means good prognosis—severity of acute disease does not predict chronic outcomes 1
Delaying ophthalmology consultation—early intervention (particularly amniotic membrane transplantation in first 1-2 weeks) can decrease chronic sequelae 3, 4
Inadequate long-term follow-up—chronic complications develop over time and require ongoing surveillance 1
Aggressive fornix manipulation without proper technique—blind sweeping causes additional damage 1
The evidence consistently demonstrates that ocular involvement is not just present in SJS—it is a defining feature requiring immediate, aggressive, and sustained ophthalmologic management to preserve vision and quality of life 2, 1.
