I've heard a lot of people talking about the Blu-Wave 488nm damaging photoreceptor cells during FAF, but haven't seen any real evidence yet. I find that if I leave the AF light on for over 10 seconds before I use ART, I get a better image. Rick Spaide spoke about this at the Spectralis Symposium in NYC last year- he suggested that you get much more autofluorescence if you "bleach" the retina with AF light for 10 seconds prior to using ART, the resulting AF is much more dramatic.

If anyone has links to literature with evidence of photo-toxicity with AF light, please share!!

Subject: [spectralis-user-group] FAF and ART

Hi,

looking for some feedback regarding what ART is appropriate for FAF imaging, and how the ART relates to the image, and what is adequate for clinical use.

specifically, does an ART higher than 15 cause harm?  say double that? at 30?

the ART goes to 100, but not sure anyone would try that with FAF.

Does anyone feel there is a time the ART should be above 15 for FAF imaging?  Should it be lower than 15?

how many people try to pre-focus the FAF using the IR as a reference, and what amount do you compensate?  How many people focus with the FAF activated?

Thanks,

John Head
