Visual Field Analyzers & Perimeters

Visual Field Analyzers (Automated Perimeters)

A visual field analyzer, or automated perimeter, measures how well a patient sees across the field of vision by presenting light stimuli at set points and recording which ones are seen. Visual field testing is a standard part of glaucoma care and is also used in neuro-ophthalmic, retinal and lid assessments.

This page brings together the visual field analyzers US Ophthalmic offers in the US: Frey automated perimeters, from compact static models to systems with both static and kinetic testing. US Ophthalmic is a US provider of ophthalmic equipment and backs every unit with an in-house technical department and spare-parts stock. Tell us which tests you run and we will recommend a model with a quote.

How to choose a visual field analyzer

• Static, kinetic or both: Static threshold testing is the routine for glaucoma follow-up. Kinetic testing maps the outer boundaries of the field and is used in neuro-ophthalmic work; choose a model with both if you need it.
• Test programs: Check that the threshold strategies, test patterns and screening programs you use are included, and how long a typical test takes.
• Fixation monitoring: Reliable results depend on steady fixation; look at how the system monitors the patient's gaze and flags unreliable tests.
• Footprint and setup: Check the space and lighting the perimeter needs, whether it has an embedded PC, and whether a monitor is included.
• Reports and data: Confirm how results are printed, exported and compared over time, and whether reports can be sent to your EMR.
• Service and parts: Ask who services the instrument in the US, how consumables and spare parts are supplied, and what the US warranty covers.

Frequently asked questions

What is a visual field analyzer used for? It maps a patient's field of vision to detect and follow conditions that cause field loss, such as glaucoma, and to assess neurological and lid-related field defects.

What is the difference between static and kinetic perimetry? Static perimetry measures sensitivity at fixed points by changing the stimulus brightness; kinetic perimetry moves a stimulus from the edge of the field inward to find where it is first seen.

Do you sell refurbished visual field analyzers? No. US Ophthalmic sells new equipment only. For a lower budget, contact us about open-box availability; open-box units are inspected and function-checked.
