What is the appropriate evaluation and treatment for a rash around the eyes in an adolescent?

Periorbital Rash in Adolescents: Evaluation and Treatment

Start with preservative-free ocular lubricants (hyaluronate or hydroxypropyl-guar drops) 2-4 times daily as first-line therapy, while immediately assessing for red flag features requiring urgent ophthalmology referral. 1

Immediate Red Flag Assessment

Before initiating treatment, evaluate for features requiring emergency ophthalmology referral within 24 hours using the RAPID acronym: 1

• Redness (severe)
• Acuity loss (any visual decline)
• Pain (moderate-to-severe)
• Intolerance to light (photophobia)
• Damage to cornea 1

Additional urgent referral criteria include: 1

• Severe purulent discharge
• History of herpes simplex virus eye disease
• Any corneal involvement 1

First-Line Treatment Algorithm

Mild Cases (No Red Flags Present)

Begin with preservative-free ocular lubricants containing hyaluronate or hydroxypropyl-guar, applied 2-4 times daily (65% response rate). 1, 2

• Preservative-free formulations are essential to avoid additional allergic contact dermatitis 2, 3
• These lubricants form a protective gel layer on the ocular surface 3

Moderate Cases (Significant Itching or Inadequate Response)

Add tacrolimus 0.1% ointment once daily to external eyelids and lid margins (89% response rate—the most effective topical treatment available). 1, 2

• Apply for 2-4 weeks 2
• Can be combined with the lubricant regimen 1
• Arrange ophthalmology review within 4 weeks when using tacrolimus 2

Consider adding olopatadine antihistamine eye drops twice daily if significant itching persists (42% response rate). 1, 2

Follow-Up Protocol

Review at 2-4 weeks to assess treatment response. 1

• Escalate therapy if no improvement or worsening symptoms 1
• Do not delay ophthalmology referral beyond 4 weeks if symptoms persist despite appropriate first-line therapy 1

Critical Pitfalls to Avoid

Never use preserved artificial tears in adolescents requiring frequent dosing, as preservatives like benzalkonium chloride cause toxicity and worsen ocular surface disease. 3

Avoid topical corticosteroids or use with extreme caution, as they may worsen the condition, cause rebound inflammation when discontinued, and lead to complications including skin atrophy, glaucoma, and cataracts. 1, 2, 3

Do not assume all periorbital rashes are benign dermatitis—while viral exanthemas, drug reactions, and atopic dermatitis are common in adolescents 4, 5, the periorbital location demands ophthalmologic vigilance for vision-threatening conditions. 1

Differential Considerations

While treating presumed periorbital dermatitis, remain alert for: 4, 5, 6

• Infectious etiologies: Viral exanthemas (EBV, HHV6), bacterial toxins (scarlet fever), or Mycoplasma-induced rash and mucositis (which can cause severe ocular involvement requiring aggressive treatment) 7
• Drug hypersensitivity: Beta-lactams and NSAIDs are most commonly implicated, though distinguishing from viral exanthema during acute phase is often impossible 5
• Systemic conditions: Kawasaki disease or vasculitis syndromes if fever and other systemic symptoms present 6

Refractory Cases

For persistent cases not responding to initial treatment: 2

• Refer to ophthalmology for moderate-to-severe cases 2
• Consider patch testing to identify specific allergens 2
• Short-term topical corticosteroids (preservative-free dexamethasone 0.1%) may be prescribed by ophthalmologists, limited to maximum 8 weeks with regular monitoring 2
