C. Light Technologies utilizes AI to diagnose Alzheimer’s by way of retinal eye research

All the sessions from Transform 2021 are obtainable on-demand now. Watch now.


C. Light Technologies has raised an investment from the Alzheimer’s Drug Discovery Foundation (ADDF) for its AI technologies that spots adjustments in eye motion to detect the earliest stage of Alzheimer’s illness.

The enterprise received this investment through ADDF’s Diagnostics Accelerator, a collaborative study initiative supported by Leonard A. Lauder, Bill Gates, the Dolby family, the Charles and Helen Schwab Foundation, Jeff Bezos, and MacKenzie Scott, amongst other folks. C. Light lately completed its second and final seed round, raising $500,000, such as the ADDF investment, which brings its total seed funding to more than $3 million.

This new investment will fund a novel pilot study with the University of California at San Francisco Memory and Aging Center to look at adjustments in fixational eye motion throughout the earliest stage of Alzheimer’s illness, typically identified as mild cognitive impairment.

The ADDF’s Diagnostics Accelerator has made prior investments in more than two dozen world-class study applications to discover blood, ocular, and genetic biomarkers, as nicely as technologies-based biomarkers to determine the early, subtle adjustments that come about in individuals with Alzheimer’s.

The purpose is to attempt to get one thing into the market place by 2023.

As new therapeutics for Alzheimer’s are introduced to the clinic, this UCSF technologies has the possible to provide clinicians with a improved strategy to measure illness progression, and eventually therapeutic efficacy, applying C. Light’s novel retinal motion technologies.

The existing lack of objective tools to assess neurological progression and disability hugely impacts pharmaceutical developers. Therapeutic development for the central nervous method is really hard, with results prices of only 8% going from conception to market place. Clinical trials can take a decade to come to fruition in this space, due to inefficient methodologies for assessing the efficacy of drugs. This is exactly where C. Light could make the largest influence.

C. Light cofounder Christy Sheehy stated in an interview with VentureBeat that the enterprise hopes to get a diagnosis machine into the market place.

Sheehy began the enterprise soon after performing a lot of study for her doctorate at the University of California at Berkeley.

“I had really started to think of the power of using AI motion, and retinal imaging, as biomarkers. And so I have family members that have, unfortunately died from neurodegenerative disease. And so for me, this is a personal passion area as well to be able to make sure that for other families, I can extend longevity and quality of life for loved ones,” Sheehy stated.

While C. Light is seeking for automating the diagnosis, existing procedures are a lot more labor intensive, as physicians and other specialists have to evaluate patients with manual testing. Sheehy hopes to construct a $15,000 machine that can be made use of at the offices of the specialists.

Before this year it had been pretty much two decades because an Alzheimer’s drug was brought to market place. Part of the cause for the slow progress is that drug developers haven’t had viable biomarkers they can use to successfully stratify patients and track illness on a fine scale. The ADDF’s investment will allow C. Light to tackle that.

Eye motion diagnostics

Eye motion has been made use of for decades to swiftly triage brain wellness, which is why a medical professional asks you to “follow my finger” with your eyes. In more than 30 years of study, research have revealed that patients with Alzheimer’s exhibit eye movements that are impacted by the illness, although these movements have only been measured on a bigger scale to date.

Sheehy stated that AI’s advances are just now coming into the technologies for diagnosing Alzheimer’s. There are other providers applying AI for retinal diagnosis for diabetes, but it is new in the Alzheimer’s and neuro degenerative space.

In the previous, C. Light has carried out research on several sclerosis and concussion scanning through retina evaluation. But the new study will focus on mild cognitive impairment as a doable early sign of Alzheimer’s. Dementia impacts a bigger body of individuals, but C. Light’s focus for now is on detecting Alzheimer’s, which is usually fatal.

“Using eye motion is a super powerful tool. So it involves many areas of the brain,” stated Sheehy. “A lot of different areas of the brain are interrelated while we move our eyes. So where you’re doing eye motion tracking, and you have an individual execute a motor task or be able to memorize or look at how to draw a clock — all of those can be potentially used as, as biomarkers. And so one of the things that we’re trying to tackle with our device is look for small movements down to about a micron in size.”

C. Light’s study requires the eye movement tests to the microscopic level for faster and earlier assessments. The enterprise says its quickly, non-invasive, and objective technologies enables clinicians to study and measure eye motion on the cellular scale — which means eye motion as little as 1/100th the size of a human hair — assisting physicians improved monitor a patient’s illness and treat it more successfully.

C. Light stated its tests are also quick for clinicians to administer. Patients place their chin in a chinrest and then focus on a target for 10 seconds. The test does not demand eye dilation, and patients are permitted to blink throughout the test. A incredibly low-level laser light is shown by way of the pupil and reflects off the patient’s retina, whilst a sensitive camera records the cellular-level motion in a higher-resolution video. This eye motion is then extracted up to 1000 instances per second and fed into C. Light’s sophisticated analytical platform.

Sheehy stated C. Light is building an completely new information stream about the status of brain wellness through the eye. She stated the company’s developing databases and accompanying AI can transform the way we monitor and treat neurological illness for future generations.

Second-round seed funders integrated ADDF, the Wisconsin River Business Angels, and Abraham Investments.

Howard Fillit, a medical professional and founding executive director at the ADDF, stated in a statement that more than 6 million individuals in the U.S. are impacted by Alzheimer’s. Technology can now gather information from patients in several approaches, and AI can locate patterns to detect early indicators of dementia. C. Light’s retinal measurement option, along with the UCSF study, will enable clinicians determine deficits and could enable for early intervention and faster therapeutic intervention, he stated.

The machines capture eye movements for roughly 10 seconds. The tech extracts the information for the movement, which can be up to 1,000 instances per second, for about 5,000 total information points. C. Light feeds that into a neural net that permits for the diagnosis of the distinctive visual signatures that would be indicators of illness. The information can be sent to the cloud, exactly where several machines could access it. Over time, the AI would get improved.
