Understand
Uveitis is inflammation of part of the uvea or other structures inside the eye.
Possible symptoms
Eye pain, redness, light sensitivity, blurred or reduced vision, flashes and floaters may develop quickly or gradually.
Causes and associated factors
The cause is often unknown; autoimmune disease, infection, injury and rarely a tumour may be responsible.
Diagnosis
An ophthalmologist promptly examines the inside of the eye to locate inflammation and assess severity.
Tests
Slit-lamp and retinal examination, eye pressure, OCT and targeted blood tests or imaging may identify causes and complications.
Course of the condition
It often responds to treatment but can recur and cause cataract, glaucoma, macular swelling or sight loss.
Care options
Anti-inflammatory and dilating eye drops are common; antimicrobial or immune treatments depend on cause and severity.
When to consult
Pain, light sensitivity, a very red eye, flashes or blurred vision require urgent assessment.
Urgent help
Sudden loss of vision or being unable to see requires immediate medical help.
