Visionstar BIO-1100

Halogen Projection Source

The stimulation source is halogen projection across the wide band visible spectrum, which the manufacturer relates to meeting coloured cone cell stimulation.

Full Goldmann Target Set

Target size covers Goldmann I, II, III, IV and V. Having the whole set available lets the operator raise target size for a patient whose responses are unreliable at the standard size.

Wide Stimulus Range

The target runs from 0.08 asb to 10000 asb, listed as 0 to 51 dB, with white background at 31.5 asb and yellow at 315 asb, and a stimulation time of 200 ms.

Blue on Yellow Examination

Standard short wavelength testing uses a 440nm blue size V target against an OG530 yellow background at 315 asb, described as sensitive to earlier field defects.

Threshold and Upper Threshold Policies

Threshold policies list macula, 10-2, 24-2, 30-2, 60-4 and nasal side. Upper threshold policies list C-40, C-64, C-76, FF-81, FF-120 and FF-135 among others.

Kinetic and Custom Policies

Dynamic policies cover standard dynamic, blind dynamic, dark spot dynamic and straight line dynamic testing, with static custom and dynamic custom policies alongside them.

Fixation Monitoring

Physiological blind spot monitoring runs with eye position monitoring, an eye position moving alarm and a recorded eye tracking curve. Pupil size and environment light testing are automatic.

Hemifield and Progression Reporting

The software lists reliability analysis, single and triple reports, a GHT glaucoma hemifield report, GPA glaucoma developing analysis, VFI analysis and blue yellow analysis.

Early Glaucoma Detection

Two listed capabilities bear directly on catching disease early. The GHT glaucoma hemifield report compares the upper and lower halves of the field, a pattern that reflects how the nerve fibre layer is organised, and the manufacturer describes it as making diagnosis easier. Behind that sits a database of the normal population across all ages, which is what allows a subtle result to be recognised as abnormal for that patient rather than simply unusual in isolation.

Short Wavelength Screening

Blue on yellow examination is provided in its standard form, using a 440nm blue size V target on an OG530 yellow background at 315 asb. The rationale is that short wavelength sensitive pathways register damage before conventional white testing does, and the manufacturer describes the examination as sensitive to earlier defects. For a practice following patients considered at risk, that offers a second view of the same field.

Progression Monitoring

GPA glaucoma developing analysis and VFI analysis are both listed, alongside single and triple reports. The manufacturer describes the progression analysis as making slight development obvious, which is precisely the judgement clinicians find hardest by eye. Reliability analysis attaches to each result, so a clinician can weigh whether an apparent change reflects the disease or simply a poorer performance on the day.

Kinetic and Occupational Testing

Dynamic policies cover standard, blind, dark spot and straight line dynamic work, giving a moving stimulus option alongside the static threshold policies. Esterman monocular and binocular tests are listed for occupational and fitness to drive questions, and an upper 36 degree screening plus blind point testing round out the shorter procedures a busy clinic reaches for.

Colour Testing Built on the Light Source

A halogen source spanning the wide band visible spectrum is what makes coloured cone stimulation practical, and everything colour related follows from it. Red and blue targets are listed, and the standard blue on yellow examination is specified down to the 440nm target and the OG530 background. A practice gaining short wavelength testing gains a genuinely different view of the field, not a variation on the one it already had, and that matters most in exactly the patients where the conventional result looks unconvincing.

Static and Moving Stimuli in One Bowl

The threshold policies handle static work from a tight macular pattern out to 60-4, while the dynamic policies add standard, blind, dark spot and straight line moving procedures. Clinics that would otherwise choose between two approaches can hold both, which suits neurological questions and advanced field loss where a moving stimulus often maps a boundary more usefully than a grid of static points ever will.

Confidence in a Difficult Examination

Perimetry lives or dies on patient concentration. Physiological blind spot monitoring, eye position monitoring, a moving alarm and a recorded tracking curve give the clinician evidence about fixation, while automatic pupil size measurement and automatic environment light testing remove two variables that quietly distort results. Combined with reliability analysis in the software, a field arrives with a clear sense of how far it can be trusted.

The Visionstar BIO-1100 is a perimeter built around colour and flexibility. Halogen projection across the wide band visible spectrum supports coloured cone stimulation, the full Goldmann target set from I to V is available, and the target range runs from 0.08 asb to 10000 asb, listed as 0 to 51 dB. Standard blue on yellow examination uses a 440nm blue size V target on an OG530 yellow background at 315 asb. Threshold policies run from macula through 10-2, 24-2, 30-2 and 60-4, with dynamic and custom policies alongside, all within a 90 degree testing scope at 30 cm.
