Is it appropriate to manage a 23‑year‑old woman with viral conjunctivitis by continuing over‑the‑counter Visine (tetrahydrozoline) drops and observation without antibiotics?

Clinical Evaluation of Treatment Appropriateness

The Treatment Plan Is Inappropriate and Potentially Harmful

The recommendation to continue Visine (tetrahydrozoline) for presumed viral conjunctivitis is inappropriate because topical vasoconstrictors should be avoided in conjunctivitis management—they provide no therapeutic benefit, cause rebound vasodilation with chronic use, and may mask progression of disease. 1

Critical Errors in This Management Plan

1. Inappropriate Medication Choice

• Visine (tetrahydrozoline) is a topical vasoconstrictor that should not be used for viral conjunctivitis. 1
• Chronic use of topical vasoconstrictors causes rebound vasodilation and actually worsens the clinical appearance over time. 1
• The patient has already been using Visine, which may be masking the true severity of conjunctival injection and inflammation.

2. Lack of Appropriate Supportive Care Recommendations

• The American Academy of Ophthalmology recommends refrigerated preservative-free artificial tears four times daily and cold compresses as the cornerstone of symptomatic treatment for viral conjunctivitis. 1
• Topical antihistamines (second-generation with mast cell-stabilizing properties) can be used for symptomatic relief of itching and discomfort, though no specific standardized dose exists in guidelines. 1
• These evidence-based supportive measures were completely omitted from the treatment plan.

3. Missing Critical Infection Control Counseling

• Strict hand hygiene with soap and water is the most important prophylactic measure to prevent transmission of viral conjunctivitis. 1, 2
• The patient should be counseled to avoid close contact for 7-14 days from symptom onset, discard multiple-dose eyedrop containers to avoid cross-contamination, avoid eye rubbing, use separate towels, and avoid sharing personal items. 1
• The note mentions no infection control education despite viral conjunctivitis being highly contagious.

Diagnostic Concerns

Clinical Presentation Does Not Fully Support Viral Conjunctivitis

• The history of "both eyes crusted over" upon waking suggests mucopurulent discharge, which is more consistent with bacterial conjunctivitis than viral. 3, 4
• Viral conjunctivitis typically presents with watery discharge, not crusting that mats the eyelids shut. 3, 4
• The physical exam findings are somewhat contradictory:
  • "No obvious signs of infection of bilateral eyes" and "no injection of the sclera bilaterally" suggest minimal active conjunctivitis
  • Yet the patient reports redness and itching that responded to Visine
  • Inflamed inferior turbinates and clear rhinorrhea suggest concurrent upper respiratory infection, which supports viral etiology 3

Missing Key Diagnostic Elements

• The exam should have documented presence or absence of follicular reaction in the inferior fornix, which is characteristic of viral conjunctivitis. 2, 5
• Preauricular lymphadenopathy should have been assessed, as it is commonly present in viral conjunctivitis. 2
• The discharge character should have been more precisely described (watery vs. mucopurulent vs. purulent). 3, 4

Appropriate Evidence-Based Management

For Confirmed Viral Conjunctivitis

• Discontinue Visine immediately. 1
• Prescribe refrigerated preservative-free artificial tears four times daily to dilute viral particles and inflammatory mediators. 1
• Recommend cold compresses for comfort and to reduce inflammation. 1, 2
• Consider topical antihistamines (second-generation) for symptomatic relief of itching, though this is not standard first-line therapy. 1
• Provide strict infection control counseling: frequent handwashing with soap and water, avoid close contact for 7-14 days, avoid eye rubbing, use separate towels, discard contaminated eye makeup. 1, 2

Red Flags Requiring Immediate Ophthalmology Referral

The follow-up plan is reasonable but should explicitly include these red flags: 1

• Visual loss or change in vision
• Moderate to severe eye pain (beyond mild irritation)
• Corneal involvement (opacity, infiltrate, or ulcer)
• Lack of improvement after 7 days or worsening symptoms
• History of HSV eye disease
• Immunocompromised state

If Bacterial Conjunctivitis Cannot Be Excluded

• Given the history of crusted eyelids upon waking, consider a 5-7 day course of broad-spectrum topical antibiotic (e.g., moxifloxacin 0.5% three times daily or ofloxacin 0.3% four times daily). 1, 6
• This provides earlier clinical remission (68% cure vs. 55% with placebo by days 4-9) and reduces transmissibility. 1
• Topical antibiotics should be avoided if viral etiology is certain, as they provide no benefit and risk adverse effects and resistance. 1

Common Pitfalls Demonstrated in This Case

• Using topical vasoconstrictors (Visine) for conjunctivitis management is outdated and potentially harmful due to rebound vasodilation. 1
• Failing to provide infection control education in a highly contagious condition puts household members and contacts at risk. 1, 2
• Not prescribing evidence-based supportive care (artificial tears, cold compresses) leaves the patient without effective symptomatic relief. 1
• Incomplete physical examination missing key findings (follicles, preauricular nodes, precise discharge character) that guide diagnosis. 2, 5
• Potential diagnostic uncertainty (crusted eyelids suggest bacterial, but exam suggests viral) should prompt consideration of empiric topical antibiotics rather than observation alone. 1, 6
