# What is a humphrey visual field (HVF) test

The Humphrey visual field (HVF) test is a standard automated perimetry test that maps central and peripheral vision. It is widely used to diagnose and monitor glaucoma and many neurological and retinal disorders.

## Test Procedure

The patient looks into a dome and fixates on a central target while dim lights are presented in different positions.

- Each time a light is seen, the patient presses a button; the machine adjusts stimulus intensity to determine sensitivity.
- Tests are performed one eye at a time and typically take several minutes.
- Reliability indices (false positives, false negatives, fixation losses) help judge test quality.
- Different programmes (for example, 24‑2, 10‑2) sample different regions of the field.

## Interpreting Results

HVF printouts show grey‑scale maps and numerical plots of sensitivity loss.

- Glaucoma often produces characteristic arcuate or nasal step defects.
- Neurological lesions may cause altitudinal or hemianopic patterns.
- Serial tests are compared to detect progression or improvement.
- Field results are interpreted alongside OCT and optic nerve findings for comprehensive care.
