Total Questions: 100
Question Types: Multiple Choice (A-D)
Format: Question + Answer Key + Explanation
--------------------------------------------------
QUESTION 1
What is the primary dye used in fluorescein angiography?
A) Indocyanine green
B) Sodium fluorescein
C) Trypan blue
D) Brilliant blue G
ANSWER: B) Sodium fluorescein
EXPLANATION: Sodium fluorescein is the standard dye for fluorescein angiography, with
peak excitation at 465-490 nm and emission at 520-530 nm.
--------------------------------------------------
QUESTION 2
During fluorescein angiography, what phase typically occurs 10-15 seconds after injection?
A) Choroidal flush
B) Arterial phase
C) Arteriovenous phase
D) Late phase
,ANSWER: B) Arterial phase
EXPLANATION: The arterial phase occurs approximately 10-15 seconds post-injection
when retinal arteries fill completely.
--------------------------------------------------
QUESTION 3
What filter combination is used for standard fluorescein angiography?
A) Excitation 490 nm, Barrier 525 nm
B) Excitation 525 nm, Barrier 590 nm
C) Excitation 805 nm, Barrier 835 nm
D) Excitation 580 nm, Barrier 630 nm
ANSWER: A) Excitation 490 nm, Barrier 525 nm
EXPLANATION: Fluorescein angiography uses excitation filters around 465-490 nm and
barrier filters around 520-530 nm.
--------------------------------------------------
QUESTION 4
Which condition typically shows "dark choroid" on fluorescein angiography?
A) Diabetic retinopathy
B) Central serous chorioretinopathy
C) Stargardt disease
D) Age-related macular degeneration
ANSWER: C) Stargardt disease
EXPLANATION: Stargardt disease often shows a "dark choroid" or "silent choroid" due to
lipofuscin accumulation in RPE cells blocking choroidal fluorescence.
,--------------------------------------------------
QUESTION 5
What is the normal retinal circulation time (arm-to-retina)?
A) 5-8 seconds
B) 8-12 seconds
C) 12-15 seconds
D) 15-20 seconds
ANSWER: B) 8-12 seconds
EXPLANATION: Normal retinal circulation time from antecubital vein injection to retinal
artery filling is typically 8-12 seconds.
--------------------------------------------------
QUESTION 6
Which layer of the retina forms the inner blood-retinal barrier?
A) Retinal pigment epithelium
B) Retinal vascular endothelium
C) Bruch's membrane
D) Choriocapillaris
ANSWER: B) Retinal vascular endothelium
EXPLANATION: The retinal vascular endothelial cells with tight junctions form the inner
blood-retinal barrier.
--------------------------------------------------
QUESTION 7
, What percentage of sodium fluorescein binds to plasma proteins?
A) 20-30%
B) 40-50%
C) 60-80%
D) 80-85%
ANSWER: D) 80-85%
EXPLANATION: Approximately 80-85% of sodium fluorescein binds to plasma proteins,
primarily albumin.
--------------------------------------------------
QUESTION 8
Which finding on fluorescein angiography indicates breakdown of the blood-retinal barrier?
A) Hypofluorescence
B) Hyperfluorescence
C) Blocked fluorescence
D) Autofluorescence
ANSWER: B) Hyperfluorescence
EXPLANATION: Hyperfluorescence indicates leakage of dye due to breakdown of the
blood-retinal barrier.
--------------------------------------------------
QUESTION 9
What is the typical dose of 10% sodium fluorescein for adult fluorescein angiography?
A) 1-2 mL
B) 3-5 mL
