Nidek just launched a new optical coherence tomography system that promises to deliver a streamlined workflow and diagnostic confidence for glaucoma and retinal vascular practices. The RS-1 Glauvas utilizes a scan speed of up to 250kHz, high-quality wide and deep area imaging, enhanced ease of operability and deep learning (DL)-based analytics.

The incorporation of 250,000 A-scans/s accelerates the workflow by reducing capture time and also addresses patient fixation errors, helping to create greater image clarity and patient comfort, according to the company. The wide-area imaging means 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 captures the oblate retinal shape of myopic eyes. Improvements in optional AngioScan OCT-Angiography include wider and clearer images for assessing chorioretinal microvasculature.

Clinical efficiency is improved by features that contribute to greater ease of operability, including auto alignment, preset scanning patterns, user-friendly interface, and diagnostic aid functions allow rapid, easy image capture and interpretation.

Advanced analytics functions for glaucoma and retinal diseases include a long axial length normative database and scan width correction help glaucoma assessment of patients with axial myopia. DL segmentation reduces artifacts and errors in the normative database and thickness maps even in eyes with opacities, Nidek says, thus decreasing false positives and enhancing clinic efficiency by reducing unnecessary follow-up visits. Additionally, the DL segmentation provides a Structural Normality Map (SN Map), which presents structural abnormalities and aids clinicians in immediately detecting minute structural changes. The result is greater diagnostic confidence, even for early signs of retinal changes, Nidek says.
