The signs and symptoms of uveitis can appear gradually or suddenly. They include:
Spots (“floaters” or myodesopsia), “flies” or “spiderwebs” floating around in the field of vision
Altered pupil size or shape
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.
