Ten Pearls in Interpreting Humphrey Visual Field. Dr. Faisal Thattaruthody,Prof. Sushmita Kaushik. A visual field encompasses the area of space or area of the

The visual field is a three-dimensional area of asubject’s surroundings that can be seen at any onetime around an object of fixation. The extent of normalvis

Perimetry is the systematic measurement of visual field function (the total area where objects can be seen in the peripheral vision while the eye is focused on a central point). The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry. Der Humphrey Field Analyzer 3 (HFA3) ist der führende, zuverlässige Analyzer in der Perimetrie. Er liefert genau die interaktive Analyse, die Sie benötigen – immer und überall. Schnellere Gesichtsfelduntersuchungen mit SITA™ Faster.

Traquair defined visual field as “ island or hill of vision surrounded by the sea of darkness” The shape of hill of vision correlates to density of photoreceptors and their receptive field sizes.

The first two editions introduced Humphrey perimetry itself (in 1986) and the internationally-based normative data application we called Statpac (in 1987). perimetry are not interchangeable. The Goldmann perimeter can also be used for manual static threshold perimetry, and other machines are also available for manual kinetic perimetry.

Since, in most eyes with retinal diseases quality of vision is greatly affected by visual field defects including paracentral scotoma and inferior field defects, visual function should be assessed by central 30- or 10-degrree automated static perimetry as well as visual acuity testing.
