Clinical Definition

A viral infection that produces inflammation of the conjunctiva (the thin, clear tissue covering the white part of the eye and inner surface of eyelid), characterized by redness, watering, and discharge. This is commonly known as "pink eye."

Documentation Requirements

• Laterality must be specified:

  • Right eye

  • Left eye

  • Bilateral

• Acuity:

  • Acute

  • Chronic

• Type of conjunctivitis:

  • Must specifically document as "viral"

  • Note any specific virus if known (e.g., adenovirus)

• Associated symptoms:

  • Presence of follicles

  • Type of discharge (watery vs. mucoid)

• Document any systemic viral illness if present

Common Synonyms

• Pink eye

• Red eye

Scribing.io Automation

The AI scribe automatically detects key phrases like:

• "Bilateral viral conjunctivitis"

• "Red eye with watery discharge"

• "Follicular reaction consistent with viral infection"

• Tracks laterality mentions

• Identifies temporal markers for acuity

• Links associated viral conditions when mentioned

When documenting, the AI will prompt for missing elements if viral conjunctivitis is suspected but documentation is incomplete.
