Advanced OCT and Adaptive Optics Imaging in Retinal Disease (The ACAD Study)

"The SD-OCT provides faster images and the ability to scan more of the central retina (macula). SD-OCT simultaneously measures multiple wavelengths of reflected light across a spectrum generating up to 40,000 A-Scans (axially sample points) per second. This allows the generation of 3 dimensional faster based volumetric images of the retina. The Spectralis OCT utilises real-time hardware eye tracking to resample lines scan enhancing the signal to noise ratio by improving the image quality.~The swept-source OCT (SS-OCT) uses a tuneable laser light source with a longer wavelength of light (typically 1040-1050 nm) that the light source seen in more conventional SD-OCT devices. The tissue penetration and resolution is greater with fast acquisition speeds and longer line scan lengths."
