Nidek introduces the RS-1 Glauvus OCT system

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.
