Is this kind of testing available around the world?

Currently no, as there is no product yet that can be distributed. We are still fine-tuning our research and applying that to make a more efficient and accurate test. We do know that this test can show amyloid-beta and can detect PET positive patients. Our hope is that this retinal scan and test can guide people who suffer from mild cognitive impairment and identify wether they should continue on to get a PET scan. We hope that this test can also help identify people who are suitable for inclusion in clinical trials of disease modifying drugs.
