Adaptive Optics Scanning Laser Ophthalmoscopy provides highest resolution possible for retinal imaging. The high resolution made it possible for in-vivo single cell imaging. Such high resolution also offers great potential for early disease diagnosis.
The picture below shows the before (left) and after (right) adaptive optics aberration correction on living human retina. Individual photoreceptor cell (~3µm) is well resolved with the help of adaptive optics.
