Posterior uveitis is less well characterised than anterior uveitis. The presenting symptoms are often floaters or blurred vision but since these are present in all forms of posterior uveitis, they have little value in differential diagnosis. The eye is white unless there is significant overspill of inflammation into the anterior chamber. Depending on the cause, there may be signs of retinal vasculitis, macular oedema or focal choroiditis.
Vision is eventually lost from cataract, glaucoma, macular oedema or retinal destruction.
Treatment depends upon the underlying cause. Systemic steroids may be necessary to suppress inflammation and avoid retinal damage.
