Answer 3

normal tension glaucoma

Question 4

what type of iris is associated with PDS glaucoma?

Answer 4

concave iris (posterior bowing iris)

Question 5

what ethnicity is more at risk for PXF glaucoma?

Answer 5

caucasians (scandinavian) and native americans

Question 6

what is a pt with PXF glaucoma at risk for?

Answer 6

lens subluxation – due to weaken zonules

Question 7

what type of tear occurs in angle recession glaucoma?

Answer 7

tear of the face of the CB from the iris root and scleral spur

Question 8

how does angle recession glaucoma appear in gonio?

Answer 8

widen CB

Question 9

steroid induce glaucoma after how many weeks of steroid use?

Answer 9

4 or more weeks after start of steroid therapy

Question 10

what are 3 types of secondary open angle glaucoma caused by inflammation?

Answer 10

1. glaucomatocyclitic crisis
2. Fuch’s heterchromatic iridocyclitis
3. uveitis-glaucoma-hyphema (UGH)

Question 11

define glaucomatocyclitic crisis

Answer 11

acute trabeculitis causes acute elevation of IOP (40-60mmHg).

Question 12

symptoms of glaucomatocyclitic crisis

Answer 12

blur, pain, nausea, vomit, HA, colored around halos
(appears like acute angle closure)

Question 13

define Fuch’s heterchromatic iridocyclitis

Answer 13

chronic non-granulomatous type of low grade anterior uveitis
signs: stellate KPs

Question 14

define UGH?

Answer 14

mispositioned IOL can result in chronic inflammation, secondary iris neovascularization, hyphema

Question 15

signs of UGH

Answer 15

uveitis, glaucoma, hyphema

Question 16

what are 3 types of secondary open angle glaucoma that is lens induced?

Answer 16

1. phacolytic
2. lens particle
3. lens dislocation

Question 17

define phacolytic glaucoma

Answer 17

lens material (protein) leaks thru lens capsule + macrophages that phagocytosed the lens proteisn + inflammatory debri clog the TM and obstruct AH outflow.

Question 18

define lens particle glaucoma?

Answer 18

liberation of lens particles after surgery or trauma clog the TM

Question 19

define lens dislocation galucoma?

Answer 19

lens becomes dislocated – anterior dislocation causes obstruction of the pupillary aperture which leads to iris bombe and angle closure.

Question 20

what kind of refractive error is associated with acute angle closure?

Answer 20

> 3D hyperope

Question 21

what ethnicity is more at risk for primary acute anlge closure?

Answer 21

asians and eskimos
