Conjunctivitis is inflammation of the surface lining (conjunctiva) of the eye.

Classification

Conjunctivitis may be classified into:[1]

  • Conjunctivitis, Allergic
  • Conjunctivitis, Bacterial
  • Conjunctivitis, Viral
  • Keratoconjunctivitis
  • Reiter Syndrome

Etiology/cause

Acute conjunctivitis may be caused by bacteria in half of cases with the most common bacteria being Haemophilus influenzae (19%), Streptococcus pneumoniae (11%), and Staphylococcus aureus (8%).[2]

Common viral causes include herpes virus and adenovirus.[3] In a small study, half of the patients with herpes virus did not have corneal ulcers or lid lesions typical of herpes virus.[3]

Diagnosis

A bacterial cause of acute conjunctivitis is more likely if there is early morning glued eye(s) and the lack of itching.[4]

Treatment

Delayed antibiotics, in which the patient is given about the course of conjunctivitis and a prescription to fill at their discretion over the next one to three days, may be the most appropriate strategy in primary care.[5][2]
