Glaucoma Flashcards
1
Q
Rate of aqueous production
A
2-3 ul/min
2
Q
Volume of AC
A
250 ul
3
Q
Different muscles of ciliary body and their functions?
A
Longitudinal -inserts to SS -outflow via traction on TM Circular -accommodation -parallel to limbus Radial -Connects longitudinal and circular
Longitudinal = Lateral Circular = Central
4
Q
Site of greatest outflow resistance in TM
A
Juxtacanalicular tissue
5
Q
Where is injury in Angle recession?
A
Btw longitudinal and circular fibers of CB
6
Q
Where is injury in cyclodialysis cleft?
A
Separation of CB from scleral spur
7
Q
Which is more potent and what are side fx?
MMC vs 5FU
A
MMC- “Much More Caustic”
- affects all phases of cell cycle
- scleral necrosis
- k ENDOthelium toxicity – k decompensation
5FU
- specific to s-phase of cell cycle
- corneal EPITHelial toxicity
8
Q
What anesthesia med increases iop
A
Ketamine
9
Q
Systemic side fx of brimonidine?
A
Adults: Lethargy and dry mouth
Kids: CNS depression, hypotension, sz
10
Q
What anesthetics increase IOP?
A
Ketamine and succinylcholine
