Near InfraredAutofluorescence (NIRAF)

Hello All,

I have recently been tasked to certify for a study that requires a NIRFAF modality using the Heidelberg HRA+OCT. This particular study is requesting M3 Field and I can't seem to get the field 3 to build any images. I usually have no problem building FAF or IR to ART 15 but this modality at field 3 seems to be impossible.

Does anyone have any experience using NIRFAF and acquiring field 3? I would like to hear any suggestions.

If you use the internal fixation light and have it look to the temporal side of the eye, it will usually put it fairly close to the F3M. If they look to far and you can't see the fovea then you might just tell the patient to look towards their temple slightly (to the right for a right eye, to the left for a left eye) and then move the camera head accordingly. There will be a shadow on one side of the image most of the time so if you want to get rid of that you can move the camera lateraly while the images is compiling to take that away. I hope that helps.
