Session 1: New and Emerging Trends in OCT Angiography

1. OCT angiography:*

a) does not have the ability to be depth resolved
b) uses flow of blood through vessels as intrinsic contrast
c) can be used to detect speed of flow
d) can be used to measure total retinal blood flow

2. In diabetic retinopathy:*

a) increasing severity is associated with lower vessel density on OCTA
b) there are no OCTA changes seen in diabetes without retinopathy
c) individual capillaries are not visualized
d) the choroid is an important part of the pathogenesis

3. Which of the following is TRUE regarding the "Ischemic Cascade":*

a) Eyes with perivenular PAMM (paracentral acute middle maculopathy) have the lowest visual acuity
b) The perivenular pole of the deep retinal vascular plexus is the first to manifest ischemia
c) An "In Parallel" circuit would best explain the ischemic cascade
d) Globular PAMM (paracentral acute middle maculopathy) is the earliest sign of the ischemic cascade

4. OCTA is useful to monitor which of the all of the following changes in eyes with uveitis EXCEPT:*

a) Nonperfusion
b) Leakage

8. Which of the following is TRUE regarding the Muller Cell and the Cone Bouquet dynamic?*

a) The Tsunoda sign, i.e. the cotton ball sign, is the earliest manifestation of this dynamic
b) The vitelliform lesion is associated with the best VA
c) Central subretinal fluid develops after the vitelliform lesion
d) This dynamic is only associated with epiretinal membrane formation

Session 3: Imaging in AMD

9. Subclinical non-exudative neovascularization:*

a) does not carry a significantly higher risk of exudation than in patients without nonexudative CNV
b) is seen in patients with phenotypic dry AMD on OCTA
c) is associated with reticular pseudodrusen

14. Please choose the statement that is false.*

a) OCT hyperreflectivity may be a marker of ischemia or retinal layer disruption.
b) Increased inner retinal hyperreflectivity correlates with worse visual prognosis in central retinal artery occlusion.
c) Increased inner retinal hyperreflectivity in ERM may indicate a better post-operative result.
