Nidek Launches the RS-1 Glauvas Optical Coherence Tomography Device

Nidek has launched the RS-1 Glauvas Optical Coherence Tomography (OCT). The RS-1 Glauvas has up to 250kHz scan speed, wide and deep area imaging, operability, and deep learning-based analytics. The incorporation of 250,000 A-scans/s accelerates the workflow by reducing capture time. The high-speed imaging also addresses patient fixation errors, thus contributing to greater image clarity and patient comfort, according to Nidek. 

"With the capability of wide area imaging, a single B-scan image clearly presents the area from the optic nerve head to the temporal vascular arcade, and the 4.2 mm depth B-scan imaging readily captures the oblate retinal shape of myopic eyes. Improvements in optional AngioScan OCT-Angiography include wider and clearer images for assessing chorioretinal microvasculature," Nidek stated in a news release. Other features include auto alignment, preset scanning patterns, user-friendly interface, and diagnostic aid functions that allow rapid, easy image capture and interpretation.

The RS-1 Glauvas incorporates various advanced analytics functions for glaucoma and retinal diseases. The long axial length normative database and scan width correction are designed to help glaucoma assessment of patients with axial myopia. Deep learning (DL) segmentation reduces artifacts and errors in the normative database and thickness maps, even in eyes with opacities, thus decreasing false positives and enhancing clinic efficiency by reducing unnecessary follow-up visits, Nidek stated. The DL segmentation provides a Structural Normality Map (SN Map) developed in collaboration with Kagoshima University. The SN Map presents structural abnormalities and aids clinicians in detecting minute structural changes at a glance, contributing to greater diagnostic confidence for early signs of retinal changes.
