For the last decade Optalert’s focus has been driver drowsiness. We are now turning our attention to other health conditions and have developed an AI-based model that tests for obstructive sleep apnoea (OSA). The condition affects 13.2% of the world’s population and it is chronically underdiagnosed: 80% of people with OSA never undergo diagnosis or treatment. To address this challenge, we are pioneering a breakthrough OSA test. It is performed on a fully awake subject, takes minutes to complete, and the result will be instantly available!
With our innovative technology, we are laser-focused on an ambitious but achievable mission:
The performance of our first version is exceptionally accurate compared to the commonly used screening tests. And it sets us up to approach a diagnostic-grade test in future iterations built on a greater volume of data.
The first stage of development of the testing device involved the following two broad steps:
Blepharometry is the study of eyelid movements. Interestingly, the eyelid is controlled by two muscles in the brain. The pons stimulates the orbicularis oculi muscle, which closes the eyelid. The midbrain stimulates the levator palpebrae superioris muscle, which opens the eyelid.
Over a long period, someone with OSA gets less oxygen to their brain as they sleep. This presents as neurological degradation and impaired coordination between these two parts of the brain. The resulting model is vastly different from our Johns Drowsiness Scale (JDS) that measures impairment from drowsiness in the immediate term. Our OSA model detects the long-term impacts of the sleep disorder.
It is remarkable how much information the eyelids give us! They truly are a window into our cognitive state.
We foresee a multitude of ways our breakthrough could transform the OSA landscape, across both active and passive screening, diagnosis, and treatment.
It offers significant advantages compared to current tests:
As with all AI models, more data will drive the test’s accuracy even higher. Our goal is for it to become a diagnostic-grade test, with accuracy nearing the gold standard of polysomnography (PSG).
This technology will have a profound impact on public health outcomes. Service providers and product manufacturers across the ecosystem will benefit. Test subjects will benefit from more reliable and readily available data. People with OSA will be given a more frictionless path to diagnosis and treatment. The longer-term comorbidities that arise from untreated OSA will be inhibited, in turn reducing public health costs.
Further development is underway. Optalert is now in the process of seeking one or more partners in the OSA ecosystem to bring this technology to market. We are confident this will positively impact the health of millions of people.
