简要总结

Retroillumination photography is difficult. The reflections on the cornea and the lens are constant and prevent from obtaining a complete and clear image. Study team have modified a slit lamp intended to photograph the anterior segment of the eye in retroillumination by using a light source in the near infrared (780 nm), and a process which eliminates the reflections.
