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
- Seven (for the macula map) and four slabs (for the disc map)
- 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.
