COMPASS Perimeter

Traditional perimetry runs on an assumption: that the patient held fixation, so each stimulus landed where the test map says it did. COMPASS removes the assumption. A built-in confocal scanning ophthalmoscope watches the retina at 25 frames per second throughout the test, records a simultaneous 60° fundus image, and ties every threshold point to a verified retinal location. When the field and the fundus come from the same instrument in the same sitting, progression calls rest on data you can defend, which is the whole point for a glaucoma practice.

Practice Fit

Where COMPASS Wins

COMPASS earns its place when the practice wants field results anchored to the retina that produced them.

Best Fit

Glaucoma-focused practices, advanced disease management, neuro-ophthalmic workups, and any doctor tired of explaining away unreliable fields.

Why This

Ask what your current perimeter does when the patient’s eye wanders. If the answer is “flags it afterward,” that is the difference: COMPASS compensates during the test, tracking the retina at 25 fps, and hands you a fundus image from the same sitting so structure and function overlay without a second instrument.

Practice Impact

Fewer fields get repeated for reliability, progression conversations rest on defensible data, and the glaucoma workup both feels and is more rigorous.

Consider Instead

If the constraint is a room you do not have, look at the Micro Medical VF2000. A headset needs no dedicated lane and travels to satellite sites. If the question is macular function rather than a full field, the MAIA answers it more directly.

Clinical Confidence

Trust What You Measure

Retinal Tracking

The tracker runs at 25 Hz for the entire test, so each threshold point maps to where the retina actually was, not where the fixation target hoped it would be.

Structure + Function

Sensitivity data lands directly on the anatomy that produced it: the confocal fundus image comes from the same test, so there is no cross-instrument alignment to trust.

Smart Progression

Smart Progression Analysis reads longitudinal change two ways, cluster-based and pointwise trends, which is how real progression gets separated from test-retest noise.

What the report looks like

The field and the fundus on one page

Every test produces two things at once: threshold sensitivity, and a confocal photograph of the retina those thresholds were measured on. Below are the outputs a doctor actually reads.

COMPASS Smart Progression Analysis report showing visual field trends

Smart Progression Analysis (SPA): Change over time, read two ways at once: deviation by cluster, and rate of change point by point.

COMPASS visual field report with integrated fundus image

Visual Field Report with Fundus Overlay: Sensitivity values printed onto the 60° retinal image they were measured from, so structure and function are read side by side.

COMPASS SmartMosaic panoramic fundus image

100° SmartMosaic Fundus Image: High-resolution TrueColor confocal panoramic view acquired during visual field testing. No additional imaging session required.
