inflammation of uveal tract
what are the 4 types of uveitis
- anterior
- intermediate
- posterior
- panuveitis
what are the 2 types of anterior uveitis?
- iritis
- iridocyclitis
what part of the eye does iritis affect?
iris
what part of the eye does iridocyclitis affect?
iris and anterior ciliary body (pars plicata)
aetiology?
- autoimmune
- prior infections (Herpes simplex and zoster etc)
- idiopathic
- trauma/infection
what can anterior uveitis be classified as (2 groups)?
Granulomatous
Non- granulomatous
what is non-granulomatous uveitis?
- acute onset
- fine KPs
- idiopathic
what is granulomatous uveitis?

- mutton fat KP’s and iris nodules
- linked to systemic conditions

HLA-B27
typical symptoms of anterior uveitis?
- Red eye
- Unilateral (bilateral or alternating if chronic)

WBCs
how do you grade cells?
SUN grading scale:
what is flare?
proteins leaked from damaged iris blood vessels - bv = increased vascularity
cells + flare =
active inflammation
flare with NO cells =
no active inflammation
