ABSTRACT:
An ophthalmological diagnostic system and method providing improved resolution and enhanced visualization of internal anatomical structures of the eye. The optical transform of light reflected and scattered by the internal anatomical structures of the eye is modified to selectively provide dark field, phase contrast and fourier filtered images, and also to provide interference patterns of difficult to visualize transparent or translucent internal structures of the eye such as the nerve fiber layer of the retina.
