Uveitis Flashcards
(46 cards)
Still’s Triad
Cataract, band keratopathy and Uveitis (chronic)
Flare is usually more noticeable
in chronic granulomatous uveitis
Plasmoid aqueous
3-4+ Grading flare, Aq is thick and white.
can be seen in severe acute uveitis.
Dense accumulation of fibrin cells producing translucent to cloudy strands or sheets with lumps of protein material
Iris Membranes
Uveitis sign
Non-fibrous membranes may come off the collaretes
3 major types type of KP
Fine (easy to detect, 3d appearance)
Granulomatous (thick, flat and waxy)
Pigmented
Fine Keratic Precipitates
Whitish-gray fibrin or epitheloid cells.
very small and adhere to posterior cornea
Granulomatous Keratic Precipitates
Greasy, waxy, grainy-appearing surfaces
looks like mutton fat
Pigmented Keratic Precipitates
Arlt’s triangle or Krukenberg’s spindle:
deposit in endothelium as well
With base down and apex up
Hypopion
Assoc with severe acute anterior uveitis
dense accumulation of white blood cells
usually PolyMorphoNuclear (PMN) cells
More common in Behcet’s, Leprosy, Endopthalmitis, Sarcoid, and post surgical uveitis
(BLES)
Anterior Synechiae:
Peripheral Anterior Synechiae or PAS
Fibrous adhesions between peripheral cornea and iris
Posterior Synechiae:
More common than anterior synechiae
Adhesions between the pupillary border and the anterior lens capsule
Form readily in all types of uveitis
Especially in the presence of flare
May occur in conjunction with iris nodules
Sometimes mistaken for persistent pupillary membranes
Seclusio Pupillae
Immobile pupil with a 360 posterior synechiae
Usually in chronic uveitis
Iris Nodules
Koeppe nodules and Busacca nodules
Koeppe nodules
Common in uveitis, round or oval tissue
Located at the pupil border
May accumulate pigment over time
Busacca Nodules:
Whitish-yellow lumps away from pupil border
In the internal iris stroma
Henkind test:
Shining a light in the non-affected pupil will cause pain in the other (consensual) pupil
iris bombe
Fluid build up btw lens and iris
lower iop in early stages is from
Due to reduced aqueous production of inflamed ciliary body
IOP may increase
Trabecular congestion may reduce outflow
Also consider iatrogenic increase in IOP due to steroid response
What types of cataracts are associated with uveitis?
Epi-capsular stars
PSC
Mature cataract
Cystoid Macular Edema occur if
inflammation is chronic
Bilateral uveitis suggests you are dealing with which type of uveitis?
endogenous and chronic types of uveitis, especially if granulomatous
Unilateral uveitis is more common in
Sarcoid, Behcet’s, foreign body, post-surgical events
When is uveitis considered chronic?
Persistent
Tends to relapse less than three months after discontinuing treatment
