Don’t shoot the messenger… even though Gunvald doesn’t justify it much further than a “trust me bro” argument, I strongly believe he is right. A small handheld device loses to a larger tabletop device in image quality because the laws of optics cannot be cheated.
There are many publications on the Aurora, but they focus on comparing diagnostic metrics between cameras. And with an optimal patient, a device with slightly poorer image quality is certainly sufficient. However, usability is what matters. How long does one screening take? How fast and easy is it to enter patient data into the machine? It looks like on the Aurora, they are typed in using the camera’s touchscreen. Seems slow.
In a study published on Optomed’s website, it was mentioned that it took 4 weeks to train a layperson to use the camera.
