Ocular photography: Comparison of a +90 Diopter Volk lens and a contact Hruby lens

1 May 1988

Abstract

Photographic slides were taken through both a +90 Diopter Volk lens and a contact Hruby lens with a photo slit lamp. Being non-invasive, the +90 D procedure was usually quicker and easier on the subject compared to the contact lens. Photos taken through the +90 D lens had more reflections, a yellow tinge, less magnification, and a wider field of view, while those taken through the contact Hruby had more shadows, truer color, more magnification, and a smaller field of view. Both were capable of providing well-focused photographs of the ocular fundus.
