IMOvifa\u2122 is a new style of perimeter
\nThe concept of \u201cIMOvifa\u2122\u201d is friendly to people, easy to use, compact design, also, aims for more accurate, more speedy and highly reliable visual field inspection.<\/p>\n

“Original program” and “original examination sequence” which achieved both accuracy and speed<\/p>\n

Original program \u201cAIZE\u201d and \u201cAIZE-Rapid\u201d<\/h2>\n

Increase the inspection speed by increasing the accuracy of the predicted value<\/h3>\n

\"\"
\nThe original program “AIZE (Ambient Interactive ZEST: a\u026az)” for determining the retina sensitivity threshold value,
\nBayesian estimation determines the stimulus intensity for each examination trial and determines the final retinal sensitivity threshold using the maximum likelihood method.
\nBy reflecting the subject’s response at each examination point to the surrounding examination points adjacent to each other, advance prediction accuracy can be improved,
\nReduce the number of trials until threshold determination. “AIZE – Rapid” is strongly reflected on the adjacent points and the inspection speed
\nI will let you up.<\/p>\n

Retinal sensitivity threshold determination with AIZE and AIZE-Rapid<\/h2>\n

Original test sequence “24 plus”<\/h2>\n

# Significant improvement in inspection efficiency<\/h3>\n

# Automatic pupil tracking
\nIndividual monitors of the pupils of both eyes during examination<\/h3>\n

\"\"
\nDuring the examination, the pupils of the left and right eyes are monitored with a near infrared camera, the position of stimuli is automatically corrected by tracking the fixation, and the accuracy of the examination is guaranteed.<\/p>\n

It is easy to use because it does not require a darkroom, and it is possible to perform highly reliable inspections<\/h3>\n

\"\"<\/p>\n

Indication of tracking correctness for each measuring point<\/h2>\n

The reliability is displayed for each measurement point by automatically detecting information (correctness of tracking) unknown only with the gaze information (it can be measured again in correspondence with the time shift mode)<\/p>\n

\"\"<\/p>\n

Defect Curve display<\/h2>\n

Total deviation displayed
\nEasy to understand by displaying total difficulty deviations<\/p>\n

\"\"
\n\n

Accurate and speedy visual field inspection is possible even though it is compact<\/h2>\n
