Your pt presents to your office with hyphema in the left eye after being hit in the eye with a football. During your exam of the retina which of the following this are you looking for in particular?
Correct Answer(s)
A. Commotio retinae
B. Macular edema
C. Chorodial rupture
Explanation
During the examination of the retina, the healthcare provider is specifically looking for signs of commotio retinae, macular edema, and choroidal rupture. Commotio retinae refers to retinal whitening or opacification caused by blunt trauma, while macular edema is the accumulation of fluid in the macula, the central part of the retina. Choroidal rupture refers to a tear or break in the choroid, the layer of blood vessels beneath the retina. These conditions can occur as a result of trauma to the eye, such as being hit with a football. The healthcare provider will examine the retina to assess for any signs of these specific injuries.

Straightened in early stages and then become tortuous over time
Some people are born with naturally tortuous vessels however
15.
BRVO/CRVO is typically caused by plaques that obstruct the blood flow.
Correct Answer
B. False
Explanation
2 main causes for CRVO:
1) impingement of artery on vein (leads to endo cell damage)
2) thickening of venous blood (BC or sickle cell)
Plaques cause CRAO/BRAO
16.
When differentiating btwn CRVO vs hemi-central CRVO, if the vessels bifurcate before the lamina cribosa it is:
Correct Answer
A. Hemi-central CRVO
Explanation
Vessel bifurcates before LC --> hemi-central CRVO
Vessel bifurcates after LC --> CRVO
17.
To determine if a CRVO is ischemic or non-ischemic, you perform a FA. At what level of capillary dropout will it be considered ischemic?
Correct Answer
B. > 10 dd
Explanation
A fluorescein angiography (FA) is used to determine if a central retinal vein occlusion (CRVO) is ischemic or non-ischemic. Ischemic CRVO is associated with more severe vision loss and has a higher risk of developing complications. The level of capillary dropout observed on the FA is used to classify the CRVO as ischemic or non-ischemic. In this case, a capillary dropout of greater than 10 disc diameters (dd) is considered ischemic.
18.
Choose the FALSE statement.
Correct Answer
C. CRAO generally causes larger VA reduction that AOAO
Explanation
The given answer is correct because it states that CRAO generally causes a larger reduction in visual acuity (VA) compared to AOAO (Acute Ophthalmic Artery Obstruction). This means that in cases of CRAO, the loss of vision is typically more severe than in cases of AOAO.
19.

20.
Impendiing macular holes typically resolve 50% of the time, otherwise treat with a vitrectomy and gas bubble
Correct Answer
A. True
Explanation
Macular holes affect women > men
Due to tractional forces of the vitreous
Early stage signs = yellow spots w/ loss of foveal depression
21.
Choose the TRUE statement abut Vitrealmacular Traction Syndrome.
Correct Answer
A. ApHakia/pseudoapHakia can be protective

- Most resolve on own w/ PVD but if VA 20/60 or worse do vitrectomy w/ ILP peel
- Present in 50% of pts over 70 yo
- can lead to CME, ERM, macular hole
- Def: partial attachment of posterior hyaloid membrane

What percentage of the population has ONH drusen?
Correct Answer
A. 1%
Explanation
The correct answer is 1%. This suggests that only 1% of the population has ONH drusen. Drusen are tiny yellow or white deposits that accumulate under the retina, and ONH (optic nerve head) drusen refers to the presence of these deposits at the optic nerve head. This condition is relatively rare, affecting a small percentage of the population.
38.
