Retina scans utilize advanced imaging technologies to capture high-resolution images of the retinal layers. For example, OCT uses light waves to create cross-sectional images, allowing for the visualization of different retinal layers. Fluorescein angiography involves injecting a fluorescent dye into the bloodstream and taking photographs of the retina as the dye passes through its blood vessels. Fundus photography uses specialized cameras to take detailed pictures of the retina.
