  • Abstract
  • Look Inside

The vertical grating images are projected onto the ocular fundus from either nasal or temporal side and the fundus is photographed in theroutine manner. And then,a fundus photograph with ver-tical grating lines can be obtained. When the surf-ace of the fundus is uneven, the grating lines are distorted. By this means, excavation of the optic disc is represented by the distortion of the grat-ing lines and it is possible to measure the amo-unt of excavation by analyzing the distortion. In the present work, the distortion was measured by densitometry.
