But i’m struggling to get usable 488 nm FAF on a Spectralis through 2+ NS; dropping to a 30° field and averaging ART 50 tightens the signal, but the image still looks muddy versus 55° with ART 9. Any tweaks to detector sensitivity or focus offset that help, or is this where you switch patients to UWF FAF on Optos to support the diagnosis?
help, or is this where you switch patients to UWF FAF on Optos to support the I’ve had better luck on Spectralis by setting IR focus, then nudging FAF focus +1–2 D anterior and dropping to ART about 20–25 while inching sensitivity up to just before speckle; if it’s still flat, I’ll try NIR‑FAF before sending to Optos. Are you focusing on live FAF or staying locked to IR?
My take: I’d lean toward the simplest next step and see if it changes anything this week — if not, you’ve got a clear case to escalate. What would block you from trying that?
, through 2+ NS I’ve had better luck staying at 55° and nudging laser power up 1–2 clicks while backing detector sensitivity down so the histogram sits just under clipping; once ART creeps past about 20–25 it just averages the haze… If it’s still muddy, I’ll grab NIR-AF on the Spectralis to support the RPE call before sending to Optos UWF unless I really need the periphery. @lhamilton33 have you seen the same gain vs illumination tradeoff?
