  • Acute anterior uveitis is characterised by red eye (ocular hyperaemia), pain and sensitivity to light (photophobia). It is not usually accompanied by a significant reduction in visual acuity, but individuals may suffer blurred vision.
  • Chronic anterior uveitis can, however, course with minimal symptoms, even without red eye and pain, and may only become evident in routine examinations or due to complications.
  • Intermediate and posterior uveitis can produce blurred vision, reduced visual acuity, floaters (myodesopsia) and, occasionally, photophobia, but normally courses without pain and red eye.
