Coherent options: Top six OCTs

The updated Nidek Retina Scan Duo 2 (RSD 2) combined high-resolution OCT and colour fundus camera (12 megapixel) benefits from high-resolution 6x6mm macula and disc OCT-A with vessel density and perfusion density displays.  

It features a retina map scan, incorporating macula and disc scans and colour fundus in one rapidly captured scan with an intuitive clinical data display. An automatic B-scan reduces noise to maximise scan resolution. The one-touch fully automated device provides exports for Opera and the Cues platform, sending OCT scans to the NHS referral service.  

An anterior module is included, while Navis 1.11 software provides a simple follow-up with progression analysis and trend prediction for advanced diagnostic understanding. The RSD 2 produces 70,000 A-scans per second and offers nine retinal scan patterns and four anterior scan patterns.
