摘要： A perimeter has an optical projection system that projects a target spot on the inside surface of a visual field dome. The position at which the target spot is projected is controlled electronically. Input devices are used to input control information to control the target spot projection position and to record patient response information. A display means provides feedback display of the control information and patient response information, and also functions as an input screen via which the control and response information is input.

摘要： When a Landolt ring optotype is presented in a visual acuity testing unit, an examinee answers a position of a slit of the optotype through an operation of a joystick lever or the like. If an examinee gives a right answer within a standard time at a first presentation of optotype, examination at a higher visual acuity grade is executed by presenting a smaller Landolt ring optotype. In case of a right answer over the standard time, reexamination at the same visual acuity grade is executed twice at the most. If a right answer is given at least once, examination at a higher visual acuity grade is executed. In case of a wrong answer within the standard time at a first presentation of optotype, reexamination at the same visual acuity is executed only once. If the right answer is given at this reexamination, examination at a higher visual acuity grade is executed. Reexamination is thus executed, so that the result of the examination is correct. In addition, the examination time can be shortened since necessary number of times of reexaminations is minimum.

摘要： In a perimeter, luminance judging means measures a sensitivity of an examinee, sensitivity deviation computing means obtains a sensitivity deviation, means for computing ratio to p value obtains a ratio to p value, and means for adding ratios to p value adds ratios to p value of respective measurement positions. The sensitivity deviation at the position where sensitivity dispersion is large is low evaluated and the sensitivity deviation at the position where the sensitivity dispersion is small is highly evaluated. Then, an element of the position where the sensitivity was changed can be also considered in a graph showing test results of perimetry periodically conducted with time.
