More narrow

Question 3

CB extends from ___ to ___

Answer 3

scleral spur to the ora serrata

Question 4

outer portion of the CB lies along the sclera separated by

Answer 4

suprachoroidal space

Question 5

Anterior insertion of the iris maybe produce a ___ angle recess known as ___.

Answer 5

Narrow angle

Pleateau iris

Question 6

most posterior structure of ACA

Answer 6

CB

Question 7

if the CB is visible at the root of the iris it’s an

Answer 7

open agle

Question 8

posterior boundary of the corneoscleral meshwork

Answer 8

SS

Question 9

anterior insertion of the longitudinal portion of the ciliary muscle

Answer 9

SS

Question 10

appears as a bright white line, separates CB from TM

Answer 10

Scleral Spur (good landmark during gonio)

Question 11

uveal meshwork is ___ layer of TM. Consists of rope like cords that extends from _____ to ____.

Answer 11

innermost

iris/CB to schwalbes line

Question 12

cornealscleral meshwork is ___ layer of TM. Extends from ____ to ____

Answer 12

middle layer

scleral spur to schwalbes line

Question 13

this layer of the TM consists of sheets of trabeculae with elliptical holes, that become smaller closer to schlemms canal

Answer 13

corneascleral meshwork

Question 14

endothelial cells line this TM layer

Answer 14

corneoscleral

Question 15

intertrabecular spaces of corneascleral TM communication with sclemms canal

Answer 15

communicate with each other but re not continuous

Question 16

juxtacanalicular meshwork is the __ layer of TM. Located where?

Answer 16

outermost

adjacent to the inner wall of sclemms canal

Question 17

this layer of TM has CT lined on either side by endothelium. What’s the difference between each side?

Answer 17

Jxtacanalicular layer
outer endothelial layer compromises inner wall of sclemms canal
inner endothelial is continuous w Trabecular endothelium
GREATEST RESISTANCE TO AQUEOUS OUTFLOW

Question 18

change in structure, function or number of trabecular endothelial cells could be related to

Answer 18

POAG

Question 19

TM lies between

Answer 19

scleral spur and scwalbes line

Question 20

circular tube lined by endothelium

Answer 20

schlemms canal

Question 21

last tissue the aqueous must traverse before entering the canal

Answer 21

the inner wall of the endothelium of sclemms canal

• bumpy
• involved with transcellular transport of aqueous

Question 22

aqueous travels from the schlemms canal to episcleral venous circulation via

Answer 22

collector channels

Question 23

demarcates termination of descements membrane

Answer 23

schwalbes line

Question 24

most anterior structure of ACA

Answer 24

schwalbes line

Question 25

pigmented SL

Answer 25

sampolesis line

Question 26

anteriorly displaced and severely hypertrophic SL

Answer 26

posterior embryotoxon

Question 27

the ACA is usually not seen without gonio because

Answer 27

critical angle is exceeded (46.5%) so light is reflected back into the eye

Question 28

iridocorneal adhesion causing tent like distortion of iris contour

Answer 28

peripheral anterior synechia

Question 29

iris processes arise from iris and insert into ---. Shouldnt be confused with synechia because

Answer 29

in sert into TM | they dont distort the normal iris contour

Question 30

Corneal wedge aids in locating

Answer 30

scwalbes line in difficult to asses angles

Question 31

grade 2 Van herick is ___ closure

Answer 31

possible

Question 32

grade 1 van herick is ___ closure

Answer 32

probable

Question 33

pupil block can cause

Answer 33

convex iris with shallow angle

Question 34

blood in the anterior chamber, common presentation after blunt trauma

Answer 34

hyphema

Question 35

Avoid gonio after ___ onset of hyphema

Answer 35

4 weeks after onset | can cause to rebleed if rough handling

Question 36

tear between longitudinal and circular muscles of the ciliary muscle associated with delayed onset 2nd open angle glaucoma

Answer 36

angle recession diagnosed as an abnormal broad ciliary body band

Question 37

abnormally wide CB band

Answer 37

angle recession

Question 38

blood in the inferior angle is

Answer 38

not detectable without gonio | microhyphema

Question 39

NVI

Answer 39

rubeosis iridis preceded by hypoxic retinal disease leads to neovascular glaucoma

Question 40

conditions associated to NVI

Answer 40

central retinal vein (or artery) occlusion diabetic retinopathy ocular ischemia uveitis

Question 41

mild ___ is common following gonio

Answer 41

SPK , if moderate-severe it can interfere with fundus examination advice pt they'll experience foreign body sensation

Question 42

gonio lens and tonometers are ____ items and require high level disinfection
