Fig. 5. Scheimpflug slit-lamp photographic images of: (A) normal; (B) cortical; (C) nuclear; and (D). Posterior subcapsular cataracts. The Scheimpflug method allows for slit-lamp imaging wherein the entire lens is in focus. The gray scale on the left of each image was built-in to aid standardization of the image during densitometry (for objective quantification of the opacities).
