Optos plc (Dunfermline, Scotland) won 510(k) clearance from the FDA for the microperimetry functions on its OptosOCT SLO system. Microperimetry is a technique that analyzes retina’s sensitivity to light and the system superimposes that over OCT (optical coherence tomography) imaging to provide a map of the correlation between physical structures and visual function of the eye.
The OptosOCT SLO is the first system to combine both OCT and microperimetry into one system. Its on-board SLO eye tracking feature adjusts for involuntary eye movements, allowing for fast imaging and coupling of the data.

- View macular and sub-retinal layer definition with absolute clarity
- Enhanced OCT images of the vitreo-retinal and the vitreous
- Capture subtle anatomical structure changes
The confocal scanning laser ophthalmoscope provides high-resolution images and retinal tracking before, during, and after the OCT scan. The SLO “Lock and Track” function ensures the follow-up scans are obtained from the same location without relying on the operator’s subjective judgment.
With the OCT SLO, both the SLO confocal fundus image and the OCT image are generated through the same optics and are pixel- to-pixel correspondent, ensuring precise OCT registration and orientation.
The high-density OCT topography data set captured simultaneously with the SLO fundus image are also generated with the same source and through the same optics, ensuring precise 3D OCT topography orientation.
The OCT SLO 3D topography provides objective measurement of thickness and volume. The SLO “Lock and Track” dramatically increase test reliability, repeatability, and reproducibility.
