Stingl et al. (1685) describe their effort to modify an existing stereophoto camera, which used a standard film-based method, to a digital imaging system. There modification utilized a custom adaptor which allowed them to mount as 21.10 megapixel full-frame digital camera (Canon EOS-5D, Mark II, Canon, Tokyo, Japan) back to a Topcon TRC-SS (Topcon, Tokyo, Japan) film-based system. High-resolution digital imaging of the optic nerve head using this simultaneous stereo system was possible with this system and the provided images were impressive, subjectively. However, only two sample images were provided in the article. It would be helpful if there was a masked qualitative and quantitative comparison of photographic quality to determine how comparable the image quality was with this conversion. Regardless, the author's method may provide a low cost way to convert existing simultaneous stereophoto systems into digital systems. This is especially important with the increasingly common transition to electronic medical record systems.
