Nidek Inc. has launched its latest optical coherence tomography (OCT) technology: the RS-1 Glauvus.

First, a company refresh.

Nidek, a manufacturer of equipment designed for diagnosing and treating vision-impairing diseases, was originally founded in 1971 in Gamagori, Japan.

With U.S. headquarters in San Jose, California, the company is a manufacturer of equipment designed for diagnosing and treating vision-impairing diseases.

Its portfolio: Ophthalmic diagnostic equipment, customized refractive surgery tools, and ophthalmic lasers for an array of conditions within the cataract, cornea, glaucoma, and retina spaces.

  • See here for a complete product list, which includes the RS-300 Advance 2 (a predecessor to the RS-1 Glauvus)

Now this OCT system.

The RS-1 Glauvas is designed with up to 250kHz scan speed—reducing capture time and accelerating workflow—and a high-quality wide/deep area imaging with deep learning (DL)-based analytics.

The result: A streamlined workflow and diagnostic capabilities for glaucoma and retinal vascular diseases, particularly in a high-volume clinical practice.

Give me some features.

  • Long axial length normative database and scan width correction (for glaucoma patients with axial myopia)
  • DL segmentation for reducing artifacts and errors in the normative database and thickness maps
  • Structural Normality Map (due to DL segmentation)
    • Provides structural abnormalities and enables physicians to detect minute structural changes (for early signs of retinal changes)

Dive deeper into these imaging capabilities.

This high-speed imaging is intended to address patient fixation errors, ideally leading to “greater image clarity and patient comfort,” per Nidek.

For example: Through this wide-area imaging:

  • A single B-scan image presents a clear area from the optic nerve head to the temporal vascular arcade
  • A 4.2 mm depth B-scan imaging can capture the oblate retinal shape of myopic eyes

Any other updates?

Yes … specifically pertaining to Nidek’s OCT-Angiography option that’s already available for the company’s OCT systems.

Standardly, this option provides the following for OCT:

  • In-depth imaging and diagnostics
    • Seven (for the macula map) and four slabs (for the disc map)
      • Macula map: vitreous, superficial, deep, outer retina, choriocapillaris, choroid
      • Disc map: vitreous, nerve head, radial peripapillary capillary plexus (RPCP), Lamina cribrosa
  • Tracing HD plus function (for image capture accuracy)
    • Tracks eye movement to maintain same scan location on the scanning laser ophthalmoscopy (SLO)
  • Selectable definition and fine mode
    • Two, four, or eight scans per line (2 HD, 4 HD, or 8 HD)
  • Wide area scan
    • Up to 12 x 12 mm image to be captured
  • Vessel density map and perfusion density map
  • Foveal avascular zone (FAZ) autodetection and shape analysis
    • Automatically detected with shape metrics for immediate assessment

What’s been added to this option for the RS-1 Glauvus?

Wider and clearer images for assessing chorioretinal microvasculature, according to Nidek.

Nice! So where can I find this system?

The RS-1 Glauvus is classified as a Class 2a CE 0344-certified product.
