Overview[edit | edit source]

Conjunctivitis may be classified based on the duration of symptoms into hyperacute, acute, and chronic.^[1][2] Additionally, conjunctivitis may be classified according to the causality of the inflammation or age groups into several subtypes: infective conjunctivitis (bacterial and viral), neonatal conjunctivitis (ophthalmia neonatorum), allergic conjunctivitis, keratoconjunctivitis sicca (dry eye syndrome), superior limbic keratoconjunctivitis, and chemical conjunctivitis.^[3][4]

Classification[edit | edit source]

Based on the duration of symptoms, conjunctivitis may be classified into hyperacute, acute (less than 3 weeks), and chronic (greater than 3 weeks).

According to the etiology and age groups, conjunctivitis may be classified into:^{[5][6][7] [8]}

• Infective conjunctivitis
  • Viral, bacterial, fungal, rickettsial, protozoal, and parasitic
• Neonatal conjunctivitis (ophthalmia neonatorum)
  • Bacterial, viral, and chemical
• Allergic conjunctivitis
  • Seasonal allergic conjunctivitis
  • Perennial allergic conjunctivitis
  • Vernal keratoconjunctivitis
  • Atopic keratoconjunctivitis
  • Giant papillary conjunctivitis
• Keratoconjunctivitis sicca (dry eye syndrome)
