2011 Heidelberg Spectralis

✅ 

IR

Infrared Reflectance Imaging

• Uses an 820 nm infrared laser.
• Great for general fundus imaging and patient eye tracking.
• Also used as a base for aligning OCT or other scans.

✅ 

BAF

Blue Autofluorescence (BluePeak)

• Uses 488 nm blue laser to detect autofluorescence from lipofuscin in the RPE.
• Helps detect early retinal pigment epithelium (RPE) damage (e.g., AMD, inherited retinal diseases).

✅ 

BAF + IR

Combined Blue Autofluorescence and Infrared Imaging

• Simultaneously captures both BAF and IR images.
• Useful for comparing structural and functional layers of the retina in one scan.

✅ 

Grid Icon (Blue Dot Pattern)

Scan Area or Pattern Selector

• Lets you choose specific scan regions (e.g., macula, optic disc).
• Commonly used for setting raster patterns, volume scans, or focal point targeting.

✅ 

H S

Likely “HS” = High-Speed or High-Resolution Scan Mode Toggle

• Lets you switch between:
• HS (High Speed) = Faster scan, lower resolution.
• HR (High Resolution) = Slower scan, higher detail (especially useful in OCT).
•
