1

def

intraocular inflammation of both the uveal tract and neighbouring structures (retina, vitreous, optic nerve)

2

what is the uveal tract

middle layer of the wall of the eye

3

what are the three main parts of the uveal tract

1 choroid (later filled with blood vessels)
2 ciliary body (ring of muscle which changes the size of the pupil and the shape of the lens)
3 the iris (coloured part of the eye)

4

what is the uvea

AKA as the uveal tract

5

epi

common
anterior uveitis > posterior uveitis

6

risk factors/associations

1 systemic inflammatory diseases such as juvenile idiopathic arthritis, RA, IBD

half of ankylosing spondylitis patients develop anterior uveitis

2 HLA B27 positive

7

what are the different classifications of uveitis

anterior (most common)
posterior

8

what is inflamed in anterior uveitis

anterior chamber

9

what is inflamed in posterior uveitis

retina or choroid

10

aetiology of anterior uveitis

1 infection (HSV, VSV)
2 as aa manifestation of systemic inflammatory conditions (juvenile idiopathic arthritis, HLA B27 spondyloarthritides such as ankylosing spondylitis, RA, IBD)
3 sarcoidosis
4 behcets disease

11

what is behcets disease

vasculitis

12

aetiology of posterior uveitis

1 infection (CMV, TB)
2 systemic inflammatory conditions (sarcoidosis)

13

history of anteior uveitis

dull pain in anterior uveitis which gets worse on accommodation (there is no pain in posterior uveitis)
redness, watering, blurred vision

14

history of posterior uveitis

no pain
blurred vision
floaters

15

examination

1 small irregular pupil
2 decreased visual acuity
3 slit lamp looking for keratic precipitates which are deposits of leukocytes on the corneal endothelium

16

what are complicationa of uveitis

increased IOP (glaucoma)
cataracts

17

investigations

diagnosis made on history and clinical examination
however investigate for associated systemic conditions like spondyloarthritides (SI joint x-ray), HLA-B27, sarcoidosis
