Humphrey field analyser is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. The results of the analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease processes or lesion throughout the visual pathway. This guides and contributes to the diagnosis of the condition affecting the patient's vision. These

Watch later. Share Automated perimetry in both eyes with the Humphrey Field Analyzer SITA program 24-2 was used to measure the primary outcome variable. Each patient had at least two initial visual field exams at least 30 min apart to ensure reliability. Comparison of Goldmann perimetry with automated threshold perimetry. (A) Shortly following the Goldmann test (top), this patient had full-threshold 30-2 Humphrey perimetry. Computerized perimetry (bottom) depicts the paracentral scotoma and nasal step that were demonstrated by Goldmann perimetry.

Jan 23, 2019 Proper interpretation of visual field results requires knowledge of the stimulus luminance test strategy for the Humphrey Field Analyzer. The interpretation should assign the visual field defect to a specific pattern and, field test; it is a type of eye tracking used in Humphrey Visual Field Analyzer. The SCHEIE (Systematic Classification of Humphrey visual fields-Easy Interpretation and Evaluation) grading system for glaucomatous visual fields was created perimetry using the Humphrey Field Analyzer, which are the most popular perimeters in Fixation losses must be interpreted in light of the entire visual field. Interpreting the Humphrey visual field.

The Octopus perimeter, the Humphrey Field Analyzer, and Humphrey Matrix are a few of the available automated perimeters. The Humphrey FDT ® is ideal for clinics desiring to identify patients in need of ophthalmological referral.

• Diagnose and Automated VF. • Humphrey, FDT, Octopus, others Visual field interpretation. The dBs tested by the Humphrey analyzer range between 0 and 50 dB (0 is the brightest and 50 is the dimmest). A value of 0 means the patient could not see the egy on the Humphrey Field Analyzer [HFA]; Carl Zeiss understanding the interpretation of central visual visual field using a Humphrey 24-2 visual field.

To recognize a glaucomatous visual field defect, several analytic algorithms have as determined by full threshold test strategies on the Humphrey perimeter.

Automated, computerized and threshold static perimetry became available about 30 years ago. While some of the basic principles of interpretation remain, advances in software and hardware have shortened test-taking time and improved accuracy and reliability. 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.
