|
ALT and SLT used on open/closed angle glaucoma
|
open
|
|
|
what % IOP reduction is expected with Laser Traveculoplasty
|
20-25%
|
|
|
How does ALT work?
|
tissue scars, pulls on collagen framework and increases aqueous outflow. scars also activate macrophages that clean up the TM, increasing outflow.
|
|
|
6 CI's of ALT
|
1) inflammatory glaucoma
2) Iridocorneal endothelial syncrome (ICE Syndrome) 3) Neovascular glaucoma 4) Synechial angle closure 5) Developmental glaucoma 6) angle recession |
|
|
size of burns in ALT and spacing
|
50 microns spaced by two burn sizes.
|
|
|
how many degrees treated in one sitting on ALT
|
180
|
|
|
power setting in ALT
|
300-1000mW
|
|
|

|
blacks
|
|
|
________ works best initally in whites
|
traveculectomy
|
|
|
What laser is used in SLT
|
Selective Laser Q-switched Nd:YAG
|
|
|
Less collateral damage and less IOP spike in a
|
SLT
|
|
|
size and spacing of burns in SLT
|
400 microns adjacent to eachother
|
|
|
where do you burn in SLT
|
border of anterior and posterior TM
|
|
|
how much energy in SLT
|
.4-1.0mJ of energy of 0.3ns
|
|
|
least inflammation and damage of TM during a
|
micropulse laser trabeculoplasty
|
|
|
laser used during a MLT
|
conventional diode lasers
|
|
|
what is MLT
|
low power short duration (0.3ms) followed by a pause in laser delivery for 1.7 ms
|
|
|
short term sucess of Sx
|
6-9 mm drop

|
long term sucess in Sx

30% failure in IOP control in first year. 5-10% failure per year
|
|
|
repeat ALT is ___% successful at 6 months and
___% successful at 2 years |
35,5
|
|
|
in filtering procedures, a ____ ____ is made from the anterior chamber allowing ____ to pass through into a ___ created in the ______ area. Aqueous is then taken up into _____ circulation
|
direct channel, aqueous, sac, appositional, body
|
|
|
which antimetabolites can be sued during the surgical proeedure to prevent scarring?
|
Mitomycin C or 5-fluorouracil
|
|
|
vision loss during traveculectomy varies between
|
6-20%
|
|
|
decreased VA from a traveculectomy usually from 3 things:
|
1) Hypotony
2) IOP spike 3) inflammation |
|
|
glaucoma tube shunts are used in:
|
pts who failed trabeculectomy, where there is very high risk, or in neovascular and uveitis glaucomas
|
|
|
4 types of shunt designs:
|
1) Molteno
