Static perimetry is currently the most commonly used type of perimetry.
Having to undergo an uncomfortable visual field test twice a year is the reality for patients with glaucoma. Both patients and medical staff have complaints about the machine and wish to see it changed.

2016;5(4):4. 6. on the FDT perimetry and the Humphrey total deviation plot showed a significant correlation for both the location and the depth of the defect. In comparing the Humphrey hemifield test with the FDT perimetry results, if at least one missed point on the frequency doubling test was considered as abnormal then the overall Humphrey tests are widely used in glaucoma clinics, the most common set up being to test the central 24° (‘24-2’ setting). Some examiners test smaller or wider visual angles; however, the wider the visual angle tested, the more coarse the grid, and hence the greater the likelihood of missing small scotomas. Frequency Doubling Perimetry Technology or Frequency Doubling Technology (FDT) Perimetry is a procedure used to detect visual field loss caused by Glaucoma and other Ophthalmological diseases. An enhanced version of FDT Perimetry has been released called the Humphrey visual field test or the Humphrey Matrix.
Some examiners test smaller or wider visual angles; however, the wider the visual angle tested, the more coarse the grid, and hence the greater the likelihood of missing small scotomas.

2. Be relatively still once positioned. 3. Always look straight ahead at the fixation target.
A Humphrey automated perimeter was used to measure the central 24 degrees of vision with static threshold targets and the peripheral field with two automatic

The ages ranged from 15 to 35 years, with a mean age of 25.9 years. The central 30 glaucoma test was used with the Synemed instrument, and the … In static threshold perimetry we map the island of vision using a different technique. Imagine determining the thickness of an island at a predetermined number of points, then using these data to construct a map of the island interpolating between the points tested (Fig. 6-11).

Reporting of visual fields should always include the actual thresholds determined for each field point and the number of false positives, false negatives and fixation losses. DISCUSSIONFDT perimetry has shown several advantages over SAP, including the following 19 : low cost; transportability; tolerance to blur, pupil size, and refractive errors 20 ; shorter test time; and lower test-retest variability.
