PACG Flashcards
AC depth less than what predisposes the pt to PACG?
LESS than 2.1mm
In an acute attack of PACG what happens to the ON?
Swelling of the ON
When IOP is elevated 40-50 why is there no response to pilo?
Pupillary sphincter may be ischemic and unresponsive to miotic agents alone.
What percent of the fellow eye of PACG develop and attack in the next 5-10 yrs?
40-80%
What drug reverses dilation?
Dapiprazole 0.5%
What is capsular block syndrome?
Retained viscoelastic or fluid in the capsular bag pushes the PCIOL anteriorly, which may narrow the angle.
Where does a FV membrane stop growing?
PAS ends at the Schwalbe’s line because FV membrane can’t grow over healthy corneal endothelium (vs ICE syndrome)
Where does iris NV start?
The pupillary margin
What % of CRVO develop angle NV?
10%
What are the demographics of ICE?
UNILATERAL; presents between 20-50 and occurs more often in women.
What is the IOP in Chandler syndrome with microcystic corneal edema?
Can be normal and NOT elevated.
In Chandler syndrome what clinical findings predominate?
- Corneal and angle findings predominate
minimal iris atrophy and corectopia occur
What is the most common of clinical entities in ICE?
Chandler - 50% of ICE cases
What % of ICE pts develop GL and in which 2 dx is it present?
50% - more severe in:
- Progressive iris atrophy
- Cogan-Reese syndrome
How do ICE endothelium differ from normal type?
Filopodial processes and cytoplasmic actin filaments are present, supporting the migratory nature of these cells.
