RTVue 3D OCT

RTVue is an ultra-high speed, high resolution OCT retina scanner used for retina imaging and analysis. It is based on the next generation Fourier-Domain Optical Coherence technology just emerging from clinical research in the last two years. The ultra-high speed and high resolution features enable the FD-OCT to visualize the retinal tissue with ultra-high clarity in a fraction of seconds.

Advanced clinic scan protocols, designed by OCT thought leaders:

Retinal scan patterns:

1. High Definition B-Scan
2. Speckle Less Image
3. Horizontal and vertical views
4. Dense thickness/elevation maps
5. Fast raster scan (click for video)
6. 3D retinal animation 1 click for video
   3D retinal animation 2 click for video
7. 3D, B-Scan, C-Scan and SLO images

Glaucoma Scan Patterns:(protocol of AIG Study, http://www.aigstudy.net/)

1. Disk/rim/cup contours and RNFL thickness map
2. Inner retinal thickness & Superior/Inferior
3. 3.45mm diameter RNFL thickness with progressive/asymmetry analysis

Benefits

The founders of Optovue have hands on experience on the development of all three previous and current generations of ophthalmic OCT products. RTVue is designed with the goal to advance the retinal diagnosis for routine clinic use in mind.

RTVue overcomes all StratusTMOCT short comings with following new features:

1. Ultra-high speed: 65 time faster (26,000A-scan/s) for 3D and high density mapping
2. High Resolution: Twice the resolution (5µm) than StratusTM OCT
3. Two scan depth range: 2mm for imaging the macular and 2.3mm for imaging a tilt disk.
4. Two image modes:
   • Vitreo mode: for better vitreoretinal tissue image
   • Choriod mode: for better chorioretinal tissue image
5. High transverse scan resolution:15µm (1/e2 spot size on retina)
6. Video fundus image: Fundus camera optical design for high quality NIR retina image
7. Non-mydriatic imaging: The pupil size required for the fundus image is 3.0mm
8. Long working distance: 22mm from cornea to ocular lens
