The Humphrey Visual Field Analyser – The Gold Standard in Perimetry

The Humphrey Visual Field Analyser is the gold standard of visual field screening used by eye hospitals. The HFA 3 Zeiss Humphrey Visual Field Screener allow Dr Janjua to offer patients the benefits of the latest state-of-the-art technology.

A visual field test measures how much ‘side’ vision you have. Using the computerised visual field analyser, Dr Janjua is able to assess the peripheral vision of the eye, which is important for evaluating the retina, optic nerve, and visual pathways within the brain.

The test detects blind spots and other visual field defects, which could indicate eye diseases such as glaucoma or conditions that affect the optic nerve. This important clinical screening may also highlight conditions such as brain abnormalities caused by strokes or tumours.

Regular Field Tests

The visual field test determines where your peripheral vision starts and ends and how well you can see objects in your peripheral vision. The optometrist can capture, track and measure your results and review information from all the analyses taken. This is important even if you have a perfect visual field as it can be used as a baseline measurement for future monitoring.

Ophthalmologist Requests

Local ophthalmologists regularly request that we carry out detailed SITA-24 field tests for their patients. This particular field test examines the field of vision in far greater detail than a standard field test, therefore giving more precise measurements and results for them to analyse.

What Does the Test Involve?

One eye is tested at a time
You will be asked to focus on a central orange light throughout the test
The machine will then flash blinking white lights in various positions in your visual field and you will press a button to let us know when you have seen the light.
All the information will be collated, and Dr. Janjua will interpret the results right away.
