Purpose. To describe an innovative imaging technique to obtain high-quality near-infrared autofluorescence (NIA) images. Methods. Simultaneous fluorescein angiography + indocyanine green angiography (FA + ICGA) acquisition mode (without dye injection) of Spectralis HRA + OCT (Heidelberg Retina Angiograph; Heidelberg Engineering, Heidelberg, Germany), setting maximum level of illuminance, and Automatic Real-time (ART) Module (Heidelberg Engineering) to increase signal-to-noise ratio. Results. The combined confocal scanning laser ophthalmoscope technique allows the Spectralis HRA + OCT device to create high-quality NIA ART images. Conclusions. This innovative imaging technique, consisting of simultaneous FA + ICGA acquisition mode, setting maximum level of illuminance, and ART, allows the Spectralis HRA + OCT device to create high-quality NIA ART images, without requiring the need for the HRA2 (Heidelberg Retina Angiograph; Heidelberg Engineering) device.
