Medical diagnostic apparatus utilizing line-of-sight detection

A medical diagnostic apparatus utilizing line-of-sight detection for diagnosing a disease related to brain function by detecting the line-of-sight of a subject, comprising:

• eye movement detecting means for detecting eye movement of said subject;
• target presenting means for presenting a target to said subject;
• calculating means responsive to a detection output from said eye movement detecting means while said subject is gazing at a target presented by said target presenting means for calculating spatial movement of the line-of-sight of said subject to determine whether or not the disease is related to brain function;
• output means for outputting the movement of the line-of-sight calculated by said calculating means and information indicating whether or not the disease is related to the brain function;
• and
• head movement detecting means for detecting head movement of said subject,
• wherein said target presenting means include means for presenting targets from different angles with respect to said subject, and
• said calculating means include means responsive to the detection output from said head movement detecting means for calculating a rotation velocity component of the head movement of said subject to output a result to said output means.
