Zeiss Glaucoma Diagnostic with Variable Corneal Compensation (GDxVCC)

View Video

This refined instrument allows precise measurement of the thickness of your Retinal Nerve Fibre Layer  (RNFL) around the optic nerve head.

Premature thinning of this layer can indicate Glaucoma and the GDxVCC is very good at detecting the progressive thinning in the early stages of Glaucoma.

RNFL analysis improves the detection, diagnosis, and management of Glaucoma.

How does it do it?

The GDxVCC measures the phase shift in a beam of polarized laser light scanning the retina at the back of the eye.

The phase is shifted by the arrangement and density of RNFL microtubules or other directional elements and tissue thickness.

The Variable Corneal Compensation (VCC) feature determines and corrects for each patient's individual non-RNFL retardation.

RNFL phase shift has been shown to closely correlate with the location and severity of RNFL structural defects in glaucoma patients.
 

Clinically proven:   GDx analysis has been proven to accurately discriminate between healthy and glaucomatous eyes and to be predictive of visual field loss. The reports are clear and intuitive.

Provides unique early case detection: The GDx is the only glaucoma imaging device with a separate Screening Mode to help us identify which patients should receive a full glaucoma examination.

Tracks change over time: The Advanced Serial Analysis feature helps us to evaluate subtle RNFL changes so we can manage glaucoma with more confidence. The Serial Analysis can only be done on GDxVCC 'Full' results, not merely the 'Screening' mode.

Simple: GDx examinations are easy for our patients, its just a matter of looking at the little red light.

Fast: Typical exam time ranges from 1 to 3 minutes

This is the instrument we rely on for our Free Glaucoma Screening days, and we give each patient a summary report of their screening scores.

We have found Glaucoma on these days, in people who had absolutely no awareness that they were going blind!
