Macula
    (Measuring range: Central 10 degrees / 21 points)
    For Macula, and neurologic disorders.

Periphery
    (Measuring range from 30 degrees to periphery points / 68 points)
    Adaptable for examining late stage Glaucoma, or peripheral field examinations, can be combined with central threshold for full field examination.

    The above 4 programs are available on some Quick modes that obtains accurate test results in minimal time (can reduce the average time by 40%).

Medidian
    (Measuring range; Any of 10 Meridians may be selected / 14 points)
    For even more detailed examination after the use of other screening programs.

Interpreting Analysis Results AP-5000C(15)

    (Measuring range from 30 degrees to periphery points / 68 points)
    Adaptable for examining late stage Glaucoma, or peripheral field examinations, can be combined with central threshold for full field examination.

1.Total Deviation⋆
    The total deviation indicates the differences between the measured values of person being tested at each test point and normal values corrected for different ages, using numeric values. The black inverted points show deterioration in sensitivity.

2.Pattern Deviation⋆
    The pattern deviation indicates the difference between the normal visual field value of person being tested (forecast from the total threshold) and the measured value, expressing this difference as a numeric value.)

3. MD (Mean Deviation)⋆
    Mean value of difference between the measured value and normal value corrected for different ages.

4. PSD (Pattern Standard Deviation)⋆
    PSD is the mean value of calculation showing how far the visual field value of person being tested has deviated. This value will be larger if there is any deterioration of local sensitivity.

    PSD is the mean value of calculation showing how far the visual field value of person being tested has deviated. This value will be larger if there is any deterioration of local sensitivity.

5. Bebie-curve
    The differences between the measured values of person being tested at each test point, and normal values corrected for different ages, are arranged in order from the largest value and indicated using a curve.
    ⋆Probability Value is available

Screening Program
    For the patient's first visit; to locate and detect defects in and efficient manner.

Standard
    (Measuring range: General / 83 points)
    For patient's first visit, or to measure vision disorder. Also adaptable for Glaucoma and Hemianopsia.

Precision
    (Measuring range: General / 140 points)
    Adaptable for measuring Glaucoma from its midstage to later stages.

Center
    (Measuring range: Central 30 degrees / 82 points)
    For Glaucoma and central vision disorders.

Periphery
    (Measuring range: From 30 degrees to Periphery / 58 points)
    To examine the progress of mid-stage Glaucoma.

Glaucoma
    (Measuring range;; Bjerrum Sphere / 117 points including nasal step)
    Comprehensive coverage of the early to later stages of Glaucoma.

V.Meridian
    (Measuring range: Vertical direction / 53 locations)
    Quickly detects Hemianopsia.

Perimetry of Fundus image
    In the ocular fundus perimetry, the visual field is examined with an ocular fundus image displayed on the screen. By overlapping the ocular fundus images and the primetery result, you can grasp the correspondence between the two.
    The data and coordinate is also with Kowa image filing system ↦ VK-2 making it possible to totally manage the fundus images and perimetry results, and ensure smooth fundus image perimetry.

Isopter Program AP-5000C(6).png

    Technology of a Goldmannand automatic perimeter are combined.
    Adaptable for measuring the peripheral field and determine the shape of visual field as isopter.
