  • Abstract
  • Look Inside

We invented "sensitometer" (apparatus for messuring the sensitivity of light in the visual field), which can messure sensitivity of various places of the retina in light room, and was used in cases of glaucoma, opto-chiasmatic tumor.

Sensitivity of the retina was found to be lowered upwards and downwards from the Marriott's blind spot in both cases with Seidel's sign and without.

In opto-chiasmatic tumor bitemporal hyposensitivity was observed even if temporal hemia-nopsia was present only one eye. Therfore, it is possible to obtain early diagnosis of he-mianopsia.
