Overview

Common causes of conjunctivitis include bacteria, viruses, and environmental factors.

Causes

• Viral conjunctivitis
  • Adenovirus, Herpes simplex virus type I and II,Varicella zoster virus during primary infection (chickenpox), Picornaviruses and Molluscum contagiosum
• Bacterial conjunctivitis
  • Gram-positive bacteria such as: Staphylococcus aureus and Streptococcus pneumoniae
  • Gram-negative bacteria such as: Pseudomonas, Serratia marcescens, Haemophilus influenzae, Moraxella catarrhalis, Chlamydia trachomatis and Neisseria gonorrhoeae
• Neonatal conjunctivitis
  • Chlamydia trachomatis, Neisseria gonorrhoeae, Herpes simplex virus, aslo chemical such as Silver nitrate solution
• Allergic conjunctivitis
  • Allergen (such as pollen, animal dander, dust mites, or molds)
• keratoconjunctivitis
  • Lacrimal gland dysfunction with reduced tear production,Reflex hyposecretion, Mucin deficiency, Low blink rate, Vitamin A deficiency, autoimmune disease, and unknown etiology
• Irritative Conjunctivitis
  • contact lenses and lens solutions, chlorine in a swimming pool, smog or cosmetics
