Breakthrough Technology - iSelfie Test for Cardio Signals

AiZtech is developing a new class of digital health technology called  "Selfie Diagnostics™". This novel modality can screen various disease states and cardiac status using a smartphone camera to scan facial and ocular topography.



This AI-powered secure technology was first be deployed as a COVID-19 screening test.

Everyone

This novel COVID-19 test is as simple as taking a selfie on a smartphone. Yes, that simple! So everyone can do a self-test and get the results in 30 seconds. 

Everyday

As it is as simple as a selfie, this non-invasive test can be done every day. Rapid testing is key for controlling COVID-19 infections when done regularly. This technology makes it a daily habit.

Everywhere

This non-contact test is run 100% online, making it accessible everywhere. It does not require a healthcare professional for administration it is not limited by the traditional supply chain.

 Why It Matters?

- The most prevalent ocular surface manifestation found within COVID-19 samples is conjunctivitis (Inomata et al., 2020). 
- Various forms have been found including follicular conjunctivitis (Aggarwal, et al., 2020) keratoconjunctivitis (Cheema et al., 2020), bilateral (Salducci et al., 2020), and unilateral (Sindhuja et al., 2020; Guo et al., 2020).
- Research shows that pathological ocular surface changes occur at the onset of COVID-19 infection at the cellular and tissue level even if ocular manifestations remain at a subclinical level.
- These ocular surface manifestations can be detectible by AiZtech's deep learning engine and used in screening and surveillance testing for COVID-19 infections. This novel modality compliment is to compliment available tools to bend the curve of infections and enable everyone to live a life unlimited by a pandemic. 

Why The Eye?

Here is a summary of key findings on how the eye plays a key role in the detection of active COVID-19 infection up to 7 days before pulmonary symptoms occur.
- SAR-COV-2 virus penetrates human cells through ACE2 receptors among others. ACE2 receptors are commonly found at cells lining the lungs nasopharynx, and nasolacrimal duct, (Bourgonje et al., 2020). 
​- Zhou et al. showed ACE2 expression on the ocular surface, predominantly on the superficial conjunctival and corneal epithelial surfaces. With this evidence, the eye can serve as a portal for viral entry and/or inoculation, (Zhou et al., 2020). 
- Other studies stated that ocular manifestations in the form of local, transient vasculitis cannot be excluded because of the high vascularity of the conjunctiva and the expression of ACE2 on the surface of endothelial cells (Aiello et al., 2020).
