Uveitis (F) Flashcards
What are the three tunics of the eye?
- scleral
- uveal
- retinal
What are the three main aspects of uveitis to consider?
- anatomical location
- timing of inflammation
- etiology
What are the three parts of the uvea (and the function of each)?
- iris (light aperture)
- ciliary body (accommodation and aqueous production)
- choroid (nourishment to outer retina)
What are the types of anterior uveitis?
- iritis
2. iridocyclitis
What are the types of intermediate uveitis?
pars planitis (includes pars plana, peripheral retina and vitreous)
What are the types of posterior uveitis?
- choroiditis
- retinitis
- neuroretinitis
What is inflammation in the entire uveal tract without predominant site called?
panuveitis
What are the cutoffs for the time periods involved in duration of uveitis?
- limited (3 months)
2. persistent (>3 months)
What course of uveitis is sudden in onset and has limited duration?
acute
What course of uveitis comes back in
chronic
What course of uveitis comes back >3M after Tx D/C?
recurrent
What course of uveitis is inactive disease >3M after Tx D/C?
remission
What are the etiologies of inflammation of uveitis?
- autoimmune
- infectious
- trauma
- inherited
- idiopathic
- masquerading
How many cells per field are in each of the grades 0-4 in the anterior chamber?
- no cells
0.5+. 0-5 cells
1+. 6-15 cells
2+. 16-25 cells
3+. 26-50 cells
4+. >50 cells
What must occur in order for tapering off steroids to begin?
2 step improvement on AC cells scale and/or flare scale
What is the milky appearance of AC due to accumulation of proteins called? 1. What is it due to? 2
- flare
2. break down of blood-aqueous barrier
What are the descriptions for flare in the AC from grade 0-4?
- complete absence
- faint (barely detectable)
- moderate (iris and lens details clear)
- marked (iris and lens details hazy)
- intense (coagulation, fibrin in AC)
What are inflammatory cells the deposit on the corneal endothelium called? 1. How many days after inflammation starts does this occur? 2.
- keratic precipitates (KPs)
2. 2-3 days after
What are the three types of keratic precipitates (which are granulomatous?)?
- small, fine, discrete, white (non-granulomatous) 1mm
3. stellate (non-granulomatous)
What are mutton fat KPs composed of?
- epithelioid cells
2. mononuclear macrophages
When are stellate KPs seen?
- Fuchs heterochromia
2. Herpes
Where do KPs usually precipitate on the cornea? 1. What is the exception? 2
- inferior half
2. stellate KPs
What are iris adhesions due to protein and fibrin in AC called? 1. What is used to break the adhesion? 2
- synechia
2. cycloplegia
