  • Abstract
  • Look Inside

Our newly developed fundus camera fitted with optical fiber bundle for fundus illumina-tion was put to clinical trial with a view to obtain higher resolution of the fundus picture.

The optical system of our fundus camera is composed of specially designed contact lens which corrects spherical aberrations of Gulls-trand's model eye and an object lens which corrects its spherical aberration. The aperture at the cornea is 5 mm in diameter. The theore-tical resolution of the whole system is about 500 lines/mm.
