Preliminary evaluation of a simple photographic cataract classification for epidemiological surveys.
A preliminary evaluation of the agreement between clinical and photographic cataract classification and its reproducibility by utilizing a very simple classification system is presented. Photographic classification was based on color Zeiss 75-SL transparencies. Results indicate that photo-derived cataract classification based on slitlamp photographs has good validity for nuclear opacities but tends to underestimate posterior subcapsular cataracts.
