FAF

Question 1

FAF reveals what using what as an indicator

Answer 1

Metabolic stress in the retina at the level of RPE using lipofuscin as an indicator.

Question 2

FAF can reveal what diseases

Answer 2

RPE and PR cell malfunctions
Dx for AMD and hereditary diseases
Areas at high risk for geographic atrophy or CNV

Question 3

Fluorescence

Answer 3

capability of absorbing light at a specific wavelength and releasing it at a longer, less energetic wavelength.

Question 4

Autofluorescence

Answer 4

Spontaneous fluorescence that some substances present naturally.

Includes PR cells containing retinoids
RPE that ingested shedded PR segments
LF collected by RPE

Question 5

LF

Answer 5

Biomarker evident in normal aging process AND chronic disease. Accumulates throughout life in RPE
Toxic and can interfere with normal cell function
Evident in ocular disease before vision declines

Question 6

Indications for FAF

Answer 6

• Less invasive than FA
• Early identification of AMD
• monitor progression of AMD
• Retinal dystrophies (Bests, Stargart)
• Glaucoma can see hyper around ONH
• Choroidal lesions

Question 7

Hypo areas

Answer 7

RPE atrophy and cell death 
Fresh hemorrhages 
Exudate lesions 
Areas of dense hyperpigmentation 
Some form of hard druse

Question 8

Hyper areas

Answer 8

Yellow lesions associated with retinal dystrophies (Bests, Stargart)
Older hemorrhages
Large and soft drusen
Glaucoma around nerve

Question 9

Billing and coding

Answer 9

92250 fundus photo with interpretation
Bilateral code
$72.62 MCR allowable
