Structured Light Entoptic Device
Introducing SLED
"World’s first adoption of Structure Light Technology in Vision Sciences"
Introducing SLED
SLED is a simple and quick tool using unique structured light to assess the health of the macula. This is done through a rapid perception task performed by patients, which quantifies their retinal health.
​
This technology allows for the screening of eye diseases such as macular degeneration, which is usually detected at a later stage with current diagnostic tools. SLED goes hand-in-hand with currently available eye treatments to help prevent vision loss and blindness.
Age-Related Macular Degeneration (AMD)
AMD occurs primarily in individuals over the age of 60. Characterized by the gradual deterioration of the macula, it can lead to a loss of central vision and difficulty with tasks like reading and recognizing faces.
-
Leading cause of irreversible blindness globally
-
​More than 200 million patients with AMD worldwide
-
No current device for screening and early diagnosis of AMD
-
Due to later diagnosis, there is no effective treatment options

Here's where SLED fits
Introducing the first and only early screening optometric device for macular degeneration. Through a simple perception test, SLED can screen healthy and non-healthy retina. See details below.
How SLED works
Structured light is a unique beam generated by SLED is tailored to match the symmetry of the macular fibres. It interacts with the retina to induce an entoptic pattern. ​

Why SLED
Easy to Use
No medical training is required to operate SLED.
​Concise
SLED outputs a single parameter which clearly indicating "healthy" vs "unhealthy" retina
Fast
No pupil dilation is required. Standard protocol timing is less than 2 minutes
Repeatable
Monitoring perception results over time allows for detection of any functional changes in the macula
