Слайд 5Early-phase Fluorescein Angiogram
Early (arterial) phase:
The most important frame
Note the

oval area of mild hyperfluorescence occurring when the retinal arteries

are just filling
The choroid is also just beginning to fill
Horizontally oriented vessels represent larger choroidal vessels seen through a rip of the RPE

Слайд 7Mid-phase Fluorescein Angiogram
Mid-phase:
Well-circumscribed hyperfluorescent area with curved outer border and

almost straight line margin adjacent to an area of relative

hypofluorescence
Findings are typical of RPE rips and should act as clues to the diagnosis

By only examining this image and the one

that follows, this can be mistaken for classic CNV
The very

early image helps to make the correct diagnosis
This can also be misdiagnosed as geographic atrophy, which has:
A border that is geographic not linear
A lesion with no overlying retinal detachment

Late phase:
Increased hyperfluorescence with mild leakage at margins
Again,

this can easily be confused with the pattern seen with

classic CNV if the entire study is not examined, including the red-free image
