-
heterochromia?
congenital diff in colouration between irides
-
Fuch's heterochromic cyclitis?
reccurent iridocyclitis
-
neural pigment abnormalities?
horner's
-
koeppe nodules?
inflammatory cell precipitates at pupillary margin
-
bussaca nodules?
on iris surface
-
congenital ectropion uveae?
- rare, non prog, neural crest disorder
- proliferation of iris pigment epithelium onto atn surface of iris from pigment ruff
-
acquired progressive ectropion uveae?
- tractional eversion of post pigment layer and sphincter muscle
- 2ndy to glaucoma and uveitis
-
iris neovascularisation?
- rubeosis iridis
- new vessel growth acros ant iris surface
-
iris attachments?
- congenital
- acquired: synechiae
-
synechiae?
- anterior: adhesions bw ant iris and post corn
- posterior: adhesions bw post iris and ant lens- seen in inflamation (uveitis/glaucoma)
-
iris bombe?
bowing of peripheral iris
-
seclusio pupillae
complete adhesion of iris to post corn
-
iridodialysis
- dishescence of iris fmor ciliary body at root
- D shaped pupil
-
freckles
- smaller than naevi
- dont distort iris
- surface pigment
-
bruschfield spots
- pale lesions in peripheral stroma
- down's
-
mammillations?
villiform lesions
-
-
NF1 lesions?
lisch, congenital ectropion uveae
-
epithelial cysts
between 2 layers of epithelium
-
stromal cyst
- dormant/2nd glaucoma
- contain flud
-
Pearl cyst
- 2ndy
- small white solid lesions
- opaque walls in stroma
- not connect wiht wound
-
serous cyst
- 2ndy
- translucent fluid filled
- connected with wound
- enlarge-> uveitis, glaucoma, edema
-
iris melanoma
- pigmented/non 3mm wide, 1mm thick
- inferior with surface vasc
- malig-> prominent bv, rapid, diffuse spread
-
ddx iris melanoma
- iris naevus
- leiomyoma- rare, benign, dervied from smooth muscle
- melanocytoma- deep pigmented nodular mass, furry, no ob vessels
-
what is ICE and RF
- iridocorneal endothelial syndrome
- abnormal clone of endothelial cell copies epit-> migrates to iris surface
- progressive enlargement and contraction of membrane-> iris traction, corectopia, ectropion-> iris atrophy
- F, white, 20-50
-
ICE 3 features?
- Chandler's
- iris atrophy
- cogan reese
-
chandler's syndrome?
- diff corn edema-> beaten bronze
- corectopia
- 2ndy glaucoma
- synechiae
-
iris atrophy in ICE?
- abnormal endo spreads onto iris surface-> forms contractile membrane
- atrophy-> heterochromia, corectopia, ectropion uveae
- iris troma and pigment epi cells atrophy
-
cogan reese syndrome?
- less severe atrophy
- tan pedunculated nodules/diff pigment lesions on ant iris
- heterocrhomia due to loss of normal iris architecture
- assoc glaucoma
-
DDX ICE?
- post polymor dystrophy- bi, ant ang and iris
- axenfeld- iridocorn adhesions in angle, similar iris, bilateral
- fuch's endothelial dystrophy- corneal endothelial appearance, without iris and angle findings
