Uveitis Flashcards
What is the uvea?
Middle vascular layer of the eye
What does the uveal tract consist of?
1) Choroid
2) Ciliary Body
3) Iris
What are the classifications of uveitis?
1) Anterior Uveitis
2) Intermediate Uveitis
3) Posterior Uveitis 1ry site
4) Panuveitis
Where is the primary site of anterior uveitis?
Anterior chamber
Where is the primary site of intermediate uveitis?
Vitreous
Where is the primary site of posterior uveitis?
Choroid
Anterior uveitis includes:
1) Iritis
2) Anterior cyclitis
3) iridocyclitis
Intermediate uveitis includes:
Pars Planitis
Posterior uveitis includes:
1) Choroiditis
2) Retinitis
3) Chorioretinitis
Most common cause of anterior uveitis?
Idiopathic
Most common cause of posterior uveitis?
Toxoplasma
Uveitis signs & symptoms:
1) Pain
2) Excessive tearing
3) Ciliary injection
4) Photophobia
5) Blurry vision
6) Floaters
Medical history is important in uveitis because 50% of patients have __.
A systemic disease
What does a slit lamp exam show in uveitis?
1) WBCs circulating in the aqueous humor of the anterior chamber
2) Protein leaks from the blood
vessels, picked out by its light scattering properties in the beam of the slit lamp as a ‘flare’
What does a pupillary exam show in uveitis?
1) Direct & consensual photophobia
2) Pupillary miosis
What signs are present in the “inflammatory” phase of anterior uveitis?
Dilated vessels
What signs are present in the “Inflammatory cells and protein exudates in the A.C” phase of anterior uveitis?
1) Aqueous cells
2) Flare
3) Hypopyon
What signs are present in the “Adhesions and clumping of inflammatory cells + fibrin deposition” phase of anterior uveitis?
1) Keratitic precipitates
2) Posterior synechiae
3) Peripheral anterior synechiae
What are keratitic precipitates?
Clumped inflammatory cells on the endothelium of the cornea, especially inferior
Iris + lens = __ synechiae
Posterior
Iris + cornea = __ synechiae
Anterior
What is posterior synechiae?
When the iris adheres to the lens and binds the pupil down
Posterior synechiae may cause:
Pupillary block glaucoma
The presence of synechiae indicates that:
The inflammation has been chronic, severe, or recurrent
Intermediate and posterior uveitis signs:
1) Cells in vitreous
2) Retinal or choroidal foci of inflammation
3) Macular edema
Where do you see Dalen–Fuchs nodules?
Uveitis
A nonspecific workup is indicated if the hx & P/E
findings are unremarkable in the presence of uveitis that is:
1) Bilateral
2) Granulomatous
3) Recurrent
What is the main treatment for uveitis?
1) Steroid eye drops if anterior
2) Systemic steroids if posterior
3) Steroid injection into the subtenon space
Steroid eye drops are given for which type of uveitis?
Anterior uveitis
Systemic eye drops are given for which type of uveitis?
Posterior uveitis
In posterior uveitis/retinitis, visual loss may occur either from:
1) Destructive processes caused by the retinitis itself (e.g. in toxoplasma or CMV)
2) Fluid accumulation in the layers of the macula (macular oedema)

What is Fuchs’ heterochromic uveitis?
A rare chronic uveitis usually found in young adults
