Question 1

Pigmentary Dispersion syndrome

Answer 1

30-40 males
From bowed iris rubbing on zonules
Trans illumination iris defects
worse on exercise (jarring and releases pigment)

Question 2

Answer 2

(I Can See The Stupid Line)
Iris
Ciliary Body
Scleral spur
Trabecular Meshwork
Schelmm's canal
Schwalbe's Line

Question 3

Aqueous is secreted by the…

Answer 3

Ciliary epithelium

Question 4

Pseudoexfoliation syndrome (PXF)

Answer 4

Age related
Systemic condition
Breakdown of basement membrane throughout the body
Flaky white deposits on pupillary margin
Sampaolesi's line

Question 5

The flow of aqueous

Answer 5

Ciliary epithelium secretes aqueous…

travels from post chamber to ant chamber then flows out of eye through TM, then to canal of Schlemm

Question 6

Which 3 types of drugs decrease the production of aqueous? (decrease outflow)

Answer 6

CAI
B-blockers
Alpha adrenergic agents

Question 7

Sunflower cataracts is associated with…

Answer 7

Wilson’s disease (copper depositing on lens)

Question 8

Which topical hypotensive is contraindicated in patients’s with pulmonary issues?

Answer 8

Timolol (beta blockers cause bronchoconstriction)

Question 9

Is treatment for PXF and Pigmentary dispersion the same as for COAG?

Answer 9

Yes

Question 10

Peripheral Iridotomy

Answer 10

Used for acute angle closure attach to increase flow of aqueous to ant chamber

Question 11

Goniotomy

Answer 11

Used in congenital glaucoma

Question 12

Trebeculectomy

Answer 12

small portion of TM removed to aid in aqueous outflow, bleb

Question 13

Angle recession glaucoma

Answer 13

Caused by blunt trauma to eye,

unilateral IOP spike, Vossius ring, ONH damage, iris tear

Question 14

Vossius ring

Answer 14

A circular deposition of pigment on the anterior capsule of the lens due to trauma

Question 15

Irididodialysis

Answer 15

A separation of the iris root from its attachment to the CB due to ocular trauma.

Question 16

Rubeotic glaucoma

Answer 16

Caused by neo in angle

Question 17

The most immediate threat to vision in acute angle closure glaucoma is…

Answer 17

CRAO

Question 18

In acute angle closure use these three meds:

Answer 18

1. Topical ocular hypotensives
2. Oral CAI
3. Hyperosmotic agents (IV Mannitol or oral osmoglyn)

Question 19

Peripheral iridotomy used for..

Answer 19

acute and chronic angle closure glaucoma

Question 20

Pred Forte

Answer 20

Topical ophthalmic steroid

risk of IOP spike

Question 21

Lotemax, FML, Alrex

Answer 21

“soft steroids” = less IOP risk

Question 22

Acular and Voltaren

Answer 22

Topical NSAID’s, no IOP spike

Question 23

Azopt (brinzolamide1%)

Answer 23

CAI that lowers IOP

Question 24

Ocular HTN

Answer 24

24-32mmHg

Question 25

Risk factors for glaucoma

Answer 25

Increase age African American Family Hx

Question 26

How does thickness of cornea correlate to IOP?

Answer 26

Thicker cornea overestimates IOP (lower IOP than the reading)
