  • Complications Acute bacterial conjunctivitis is almost invariably a disease with a highly favourable prognosis.[onlinelibrary.wiley.com]
  • Prognosis of viral conjunctivitis Viral conjunctivitis is extremely contagious and remains so for 14 days, which also is often how long the symptoms remain. The prognosis is very good for viral conjunctivitis.[intechopen.com]
  • Prognosis [ 11 ] Eyelid and conjunctival lesions tend to resolve over 1-2 weeks. Epithelial keratitis resolves over two weeks and has a good prognosis. Stromal keratitis is more likely to result in corneal scarring.[patient.info]
