Perimetry with Zeiss Humphrey FDT. Biometry Cataract Surgery Pretests diagnostic methods (eg, assessment of fundus photographs, visual field and OCT)

Light is projected into a white bowl with a standardized background light intensity. The most common threshold test carried out in an automated perimetry test (i.e Humprey visual field) is Central C24-2. This test means that the central 24 degrees of the visual field were analysed. This test is most often used to detect central visual field defects. Static automated perimetry (such as Octopus or the Humphrey Field Analyzer): Pinpoint flashes of light of varying size and brightness are projected within a large white bowl.

Humphrey perimetry test

The nature of these tests required specific test algorithms with clearly defined test sequences and termination criteria. The method adopted in the Humphrey Visual Field Analyzer (HFA) was to use the standard full-threshold strategy at four visual field locations (12.7° from fixation along the 45, 2000-01-01 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 Humphrey automated threshold perimetry (Program 30-2) was performed on 42 eyes of 25 patients with glaucoma to determine both the sensitivity and specificity of automated perimetry in detecting The Zeiss Humphrey HFA-II 700’s series is the Gold standard in perimetry. The most widely used perimeter in the world, provides standard and custom tests per the Doctors preferences. Fast testing features while maintaining accuracy and repeatability every time.

The mean deviation (MD) of Humphrey central 10-2 perimetry is useful in predicting the visual outcome in eyes with exudative AMD after photodynamic therapy or intravitreal injection of anti-vascular endothelial growth factor.

GDx VCC, Stratus OCT Perimetry (or visual field testing) is a vision test used to evaluate a patient's peripheral vision. It involves a patient fixating on a central target and pressing a button when they see a spot of light in their peripheral vision. It is an important way of deciding whether Glaucoma is progressing or not. In flicker perimetry, test‐points at the same locations as in the Humphrey program 24–2 were selected for generating the ROC curves. The glaucoma patients were classified as early (MD > − 6 dB) moderate (6 dB ≥ MD > 12 dB) and advanced (MD ≤ −12 dB) using the HFA.

The test measures the central 24 to 30 degrees of the visual field; that is, the area measuring 24 to 30 degrees around the point of fixation. The Humphrey Field Analyzer central 30-2 threshold test (HFA 30-2) and central 24-2 threshold test (HFA 24-2) are tests that can meet these criteria.
