Visionstar APS-6000

Light Emitting Diode Stimulus

The stimulus type and stimulus source are both listed as light emitting diode, giving a solid state light source rather than a projected one at the heart of the examination.

Integrated Hemispherical Bowl

The stimulator screen is an integrated hemispherical bowl with a radius of 30cm, which is the conventional geometry for a seated field examination.

Stimulus Intensity and Size

Stimulus intensity is listed at up to 10000 asb with background illumination of 4 asb, and stimulus size is given as Goldmann III, the size used routinely in field work.

Adjustable Duration and Delay

Stimulus duration is adjustable from 0.2 to 2 seconds and the minimum delay between stimuli across the same range, so pacing can be matched to how quickly a patient responds.

Yellow and Red Stimulus

Stimulus colour covers yellow and red. A dedicated yellow spot test across the central 0 to 10 degrees is listed among the test range options.

Four Point Densities

The data lists 144 points across 0 to 60 degrees, 72 across 0 to 30 degrees, 61 red points across 0 to 10 degrees and 114 points for blind spot testing.

Two Fixation Methods with Warnings

Automatic monitoring offers a blind spot method and an eye tracking method. Fixation errors are announced immediately by visual and audible warnings during either.

Video Camera and Windows Software

A standard video camera gives the operator sight of the patient's eye for additional monitoring, and the software is described as developed on a Windows platform with an intuitive report.

Routine Central Field Testing

The central 0 to 30 degree test, backed by 72 stimulus points across that area, covers the region where most clinically significant loss declares itself. For a practice running regular reviews, this is the workhorse procedure. Stimulus duration and inter stimulus delay adjust from 0.2 to 2 seconds each, which matters more than it sounds: a patient who responds slowly can be given time without the software recording hesitation as a missed point.

Peripheral and Quadrant Assessment

A peripheral test covering 60 to 90 degrees sits alongside a quadrant test and a default test spanning 0 to 60 degrees with 144 stimulus points. Field loss arising outside the central region, or confined to one quadrant, is exactly what a central procedure can miss, so having dedicated procedures for both means a clinician can follow a suspicion outward rather than settling for what the standard pattern happened to sample.

Yellow Spot and Blind Spot Procedures

A yellow spot test covers the central 0 to 10 degrees, supported by 61 red stimulus points across that same area, and a dedicated blind spot test draws on 114 points. The blind spot procedure has a double value here, since one of the two automatic fixation monitoring methods works from the physiological blind spot, tying the reliability check to a structure every patient has.

Reliability in Difficult Patients

Two automatic fixation methods, immediate visual and audible warning of fixation errors, and a video camera showing the operator the patient's eye combine to address the perennial weakness of perimetry. An unreliable field looks like disease, and a clinician who cannot tell the two apart is left repeating examinations. Being alerted at the moment fixation slips allows the operator to intervene while the test is still running.

A Solid State Light Source

Listing light emitting diodes as both the stimulus type and the stimulus source puts a solid state emitter where many instruments place a projection assembly. For a clinic, the appeal of that architecture is simplicity: fewer moving optical parts between the source and the bowl surface. What the arrangement means for servicing intervals and consumables is not stated on the material held, so it is worth raising with Medigear.uk alongside the rest of the specification.

Pacing That Follows the Patient

Both the stimulus duration and the minimum delay between stimuli are adjustable from 0.2 to 2 seconds. That range covers the brisk pace suitable for an alert younger patient and the slower rhythm an elderly or anxious person needs. Since fatigue is the main enemy of a usable field, the ability to set both parameters rather than one gives the operator genuine control over how demanding the examination becomes.

Fixation Errors Caught as They Happen

Automatic monitoring runs by a blind spot method or an eye tracking method, with errors announced immediately through visual and audible warnings, while a video camera shows the operator the eye itself. The value lies in the timing: a warning during the examination lets the operator steady the patient and continue, where a reliability figure discovered afterwards only tells a clinic that the appointment was wasted.

The Visionstar APS-6000 puts a light emitting diode stimulus inside an integrated hemispherical bowl of 30cm radius, working at up to 10000 asb against a background illumination of 4 asb with a Goldmann III stimulus size. Duration and the minimum delay between stimuli each adjust from 0.2 to 2 seconds, stimulus colour covers yellow and red, and point densities run from 144 across 0 to 60 degrees down to focused sets for the central and blind spot procedures. Two automatic fixation methods with immediate visual and audible warnings sit behind all of it.

This page states what the technical data states. Housing dimensions, mass, electrical supply, software version, variant designation, configuration and condition do not appear reliably on that material, and nothing here should be read as a claim about testing or regulatory approval. Medigear.uk will confirm each of those points.

If your practice needs a straightforward bowl instrument covering central, peripheral, quadrant and blind spot work, and you want the specification checked against the patients you actually see, speak to Medigear.uk. As a verified medical equipment supplier working across medical, dental, rehabilitation and aquatic therapy settings, the team will confirm what this instrument offers and help you judge whether it belongs in your clinic.
