What part of the eye is affected by posterior uveitis?

A

Choroid

18
Q

What type of uveitis has the poorest prognosis?

A

Posterior uveitis - because it damages parts of the eye which are critical for vision - I.e. retina, macula and the optic nerve.

Q

What type of uveitis is usually most symptomatic?

A

Anterior uveitis is usually most symptomatic (particularly when it happens acutely). Patients will complain if pain, red eyes and blurry vision. However, interestingly, symptoms can decrease with recurrent episodes, and in patients with chronic uveitis (e.g. JIA-associated uveitis) these episodes can be asymptomatic.
