Uveitis (inflammation of the iris, ciliary body and/or choroid) is the most common ocular inflammation. It can occur either as an autoimmune response (such as reactive arthritis, ankylosing spondylitis, Crohn’s disease, etc), or injury, infection or exposure to toxins. (3)
The symptoms can be chronic and mild, or even asymptomatic, with redness of the conjunctiva more concentrated around the limbus, blurred vision and photophobia. Sometimes it manifests as a dull pain as opposed to purely surface symptoms of
grittiness, dryness or itching. It must not be underrated as a danger to vision, as untreated it can be responsible for permanent vision loss; it is responsible for 10 per cent of visual impairment in the Western world. (4)
Acute anterior uveitis is the most common of a number of different forms of uveitis and is characterised as rapid onset of unilateral pain, photophobia and hyperaemia. Chronic anterior uveitis is less common and may not display any symptoms until cataract or band keratopathy develops. Typically, for this form of ocular inflammation, a corticosteroid with mild to high potency would be used, either prednisolone or one its many derivatives (names generally end in ‘one’ or ‘nol’).
