1

What two components of the eye make up the anterior uvea?

Iris

Ciliary Body

2

Posterior Uveitis involves which portion of the eye?

Choroid

3

What clinical signs are associated with uveitis?

Photophobia

"Red-Eye" consistent with conjunctival hyperemia

Epiphora or Seromucoid Discharge

Blepharospasm

Third Eyelid Elevation

4

What is seen on ophthalmic exam that is pathognomonic for anterior uveitis?

Aqueous flare

5

What is seen in the image below and what disease processes are they associated with?

Keratic Precipitates associated with Anterior Uveitis

6

What is seen in the image below?

Anterior Synechia - Adherence of the iris to the cornea

7

What causes aqueous flare?

Aqueous flare occurs secondary to the break-down of the blood-aqueous barrier and release of protein/cells into the anterior chamber from the iridal and ciliary vessels. Basically, the vessles become hyper-permeable so stuff leaks out of them.

8

What three things are needed to observe aqueous flare?

1. A dark room

2. A focal light source

3. Appropriate positioning

9

What are the four causes of anterior uveitis? Which is the most common

Idiopathic (most common - 50-70%)

Intraocular (cataracts, intraocular tumors)

Infectious (4 F's and T, B)

Neoplastic (Lymphoma)

10

What is the most common intra-ocular tumor in cats?

Diffuse Iris Melanoma

11

What are the 6 infectious causes of anterior uveitis?

4Fs, T, and B

FeLV (Feline Leukemia Virus)

FIV (Feline AIDS)

FIP (Feline Infectious Peritonitis)

Fungal (Cryptococcus)

T (Toxoplasma gondii)

B - Bartonella henselae

12

How do we treat Anterior Uveitis?

Treat the underlying cause

Nonspecific therapies:

Topical Steroid

Topical Mydriatic (Atropine) if the IOP is low or normal

Oral Steroid if negative for infectious disease
