Classification Of Uveitis

I. ANATOMICAL CLASSIFICATION
1. Anterior uveitis. It is inflammation of the uveal
tissue from iris up to pars plicata of ciliary body.
It may be subdivided into :
Iritis, in which inflammation predominantly
affects the iris.
Iridocyctitis in which iris and pars plicata part
of ciliary body are equally involved, and
Cyclitis, in which pars plicata part of ciliary
body is predominantly affected.
2. Intermediate uveitis. It includes inflammation of
the pars plana and peripheral part of the retina
and underlying ‘choroid’. It is also called ‘pars
planitis'.
3. Posterior uveitis. It refers to inflammation of the
choroid (choroiditis). Always there is associated
inflammation of retina and hence the term
‘chorioretinitis’ is used.
4. Panuveitis. It is inflammation of the whole uvea.
II. CLINICAL CLASSIFICATION
1. Acute uveitis. It has got a sudden symptomatic
onset and the disease lasts for about six weeks
to 3 months.
2. Chronic uveitis. It frequently has an insiduous
and asymptomatic onset. It persists longer than
3 months to even years and is usually diagnosed
when it causes defective vision.
III. PATHOLOGICAL CLASSIFICATION
1. Suppurative or purulent uveitis.
2. Non-suppurative uveitis. It has been further
subdivided in two groups (Wood’s classification).
(i) Non-granulomatous uveitis, and
(ii) Granulomatous uveitis

IV. ETIOLOGICAL (DUKE ELDER'S)
CLASSIFICATION
1. Infective uveitis
2. Allergic uveitis
3. Toxic uveitis
4. Traumatic uveitis
5. Uveitis associated with non-infective systemic
diseases
6. Idiopathic uveitis
