- 1.
In acute papilledema, what is the pupillary response?
Correct Answer
Normal - 2.
An optic nerve lesion affecting the nasal radiating fibers of the retinal ganglion cells produces what kind of visual field defect?
Correct Answer
Temporal wedge - 3.
What kind of telangiectatic vessels are present in LHON?
Correct Answer
peripapillary - 4.
The telangiectatic vessels in LHON leak on FFA.
- A.
True
- B.
False
Correct Answer
B. False -
- 5.
What process causes the yellowish hazzy appearance of the optic disc border in optic disc drusen?
Correct Answer
axoplasmic stasis - 6.
Buried disc drusen are often accompanied by increased branching of the retinal vessels.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This includes anomalous branching such as loops and trifurcations. Other features associated with buried drusen include scalloped appearance of the disc margin, peripapillary RPE dispersion, and a grey/black region adjacent to the disc.Rate this question:

- 7.
What anatomic feature is responsible for congenital "fullness" of the optic disc?
Correct Answer
small scleral canalExplanation
The optic disc can also appear full from hyaloid remnants, glial tissue on the disc surface, fullness from hyperopia and buried disc drusen.Rate this question:
- 8.
Which of the following is NOT associated with optociliary shunt vessels (retinochoroidal vessels)?
- A.
CRVO
- B.
Chronic papilledema
- C.
CRAO
- D.
Optic nerve sheath meningioma
Correct Answer
C. CRAOExplanation
Retinochoroidal collaterals are pre-existing venous channels that dilate in response to chronic CRVO, or obstruction of outflow. They characteristically dive deep into the choroid immediately adjacent to the disc. Other causes include sphenoid wing meningioma and optic glioma.Rate this question:
-
- 9.
Which of the following is FALSE regarding refractile bodies of the optic disc, seen in chronic papilledema?
- A.
They tend to be small and non-calcified.
- B.
They usually remain on the disc surface.
- C.
They cluster around the disc margin.
- D.
They do not disappear with the resolution of papilledema
Correct Answer
D. They do not disappear with the resolution of papilledema -
- 10.
Which of the following medications is not associated with IIH?
- A.
Tetracycline
- B.
Corticosteroids
- C.
ACE inhibitors
- D.
Nalidixic acid

Correct Answer
C. ACE inhibitors -
- 11.
A middle ear infection can mimic IIH.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A middle ear infection can cause cerebral venous obstruction, causing increased ICP. Other causes of cerebral venous obstruction include trauma, childbirth and a hypercoagulable state. Other causes of decreased venous outflow include systemic or localized venous obstruction (such as radical neck dissection), a dural AVM and systemic vasculitis.Rate this question:
-
- 12.
Which of the following is similar between pediatric and adult IIH?
- A.
Headache
- B.
Cranial nerve involvement
- C.
CSF opening pressure
- D.
Patient profile
- E.
Treatment
Correct Answer
E. TreatmentExplanation
Pediatric IIH is commonly associated with papilledema without headache. There are more boys and non-obese patients affected. CSF opening pressures are different, and often multiple cranial nerves (III, IV, VI, VII, IX, XII) are involved, which resolves with treatment.Rate this question:

Optic disc edema may precede vision loss in AION.
- A.
True
