LSFG-NAVI Flicker System |
Flicker stimulates photoreceptor cells
Photoreceptor cells require additional oxygen
Decreased vascular resistance and increased blood flow |
This system can be used to measure elevated blood flow before, during, and after stimulation. |

Measuring not just blood flow volume, but its waveform — the quality of flow — to capture the earliest signals of vascular change. That is what LSFG makes possible.
Softcare is the company that first commercialized LSFG technology as a certified medical device, and continues to advance it.
Every cell in the human body depends on blood flow to receive oxygen and nutrients, and to remove metabolic waste. From the heart to the brain, to the eye, to the fingertips — blood flow sustains every organ, every moment.
Impaired blood flow underlies many of the most serious diseases known to medicine. What these conditions share is a common origin: disruption of blood flow at the microvascular level.
Critically, changes in blood flow often precede structural damage. Observing blood flow continuously offers a window into the earliest stages of disease — before irreversible harm has occurred.
The dynamic pattern of each cardiac cycle — systolic peaks, diastolic troughs, pulsatility indices — carries far richer data about the true condition of the microvasculature than volume alone.
The fundus is the only tissue in the human body where blood vessels can be observed directly, low-invasively, and in real time. Fundus microcirculation reflects the systemic microvascular environment — making the fundus a uniquely privileged window into the body's vascular health.
Softcare is the company that first commercialized LSFG technology as a certified medical device, and continues to advance it.
LSFG technology has been utilized in a broad and growing range of research fields, reflecting the fundus's unique position as a direct and low-invasive observation point for microvascular physiology.
Blood flow assessment holds the potential to inspire entirely new research themes — from the elucidation of disease mechanisms to a deeper understanding of human health. We look forward to the discoveries that lie ahead, together with researchers worldwide.
Blood vessels are working quietly, right now.
Our mission: to bring the technology that listens
to their voice — to the world.
