The Fundamentals

How do I interpret an IVFA?

• This is an intravitreal fluorescein angiogram of the right/left eye.

• This image is captured at __ seconds, in the __ phase. This is evidenced by: justifying what you can see.

• I will begin by describing the optic disc.

• For example, note if you see more hyperfluorescence than expected, leakage, filling defects.

• Now I will continue by describing the vessels.

• Describe areas of hypofluorescence.

• Classify its location (superior, inferior, nasal, temporal, peri-papillary, periphery, along the arcade etc.).

• Classify as either: a blocking defect or a vascular filling defect.

• Describe areas of hyperfluoresence.

• Classify its location (superior, inferior, nasal, temporal, peri-papillary, periphery, along the arcade etc.).

• Describe it as either: pseudofluoroesence, autofluorescence, a transmission defect, leakage, pooling or staining.
