Static perimetry is often undertaken with the Humphrey automated perimeter (Humphrey Instruments, Dublin, CA), whilst kinetic perimetry has most commonly been undertaken using the Goldmann manual perimeter (Haag Streit, Switzerland). Both options, when directly compared, have been shown to reliably detect visual field loss [ 1 – 6 Measurements for Humphrey perimetry were significantly smaller for superior and inferior visual field and rotations with ceiling effects at approximately 40 and 50 degrees, respectively. Automated static threshold perimetry measures the retina’s sensitivity to light at predetermined locations in the visual field. While the individual focuses on a specific point, called the point of fixation, stimuli are presented in random order at each of the predetermined locations within the visual field. Static automated perimetry uses a machine to quantify how well a person is able to detect flashing lights of varying size and brightness in different quadrants of the visual field while looking directly and steadily at a central point within a dome.

Automated static perimetry—and threshold perimetry specifically—presents a stimulus of fixed size but of variable intensity. The sensitivity of the different test locations is recorded based on the patient's responses to these stimuli. A size III stimulus (which is 4mm 2 when projected on a 30cm bowl) is commonly used in clinical practice.

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. Comparison of octopus semi-automated kinetic perimetry and humphrey peripheral static perimetry in neuro-ophthalmic cases. Rowe FJ, Noonan C, Manuel M. ISRN Ophthalmol. 2013;2013:753202. doi: 10.1155/2013/753202. In standard static perimetry, objects of varying sizes and shapes remain fixed in position (hence static) across the visual field, but change in luminosity or size via computer control. These perimeters offer up to 80 degrees of measurement range across the hemisphere.

Advances in computer technology have facilitated more sensitive and reproducible … SERVICES Humphrey Automated PerimetryWhat is Automated Perimetry? Automated Static perimetry is the most important clinical tool for measuring visual function outside the fovea.Threshold testing involves precise quantification of visual sensitivity.while suprathreshold testing is used mainly to establish whether visual function is within the normal range. 2000-01-01 METHODS: Humphrey 10-2 perimetry results and visual acuity were studied in the right eyes of 69 patients with typical RP. Patients whose eyes had cataract, glaucoma, cystoid macular edema, or other complications affecting vision were excluded. As the gold standard of perimetry, Humphrey ® Field Analyzer 3 (HFA3) is your trusted diagnostic partner.
