This app is a tool to help you capture better images using your Peek Retina Product by optimising your camera settings for fundus imaging. When using Peek Retina to examine a dilated eye you need to examine the optic disc and the macular area. The phone’s standard settings make it easier to capture disc images but difficult to capture areas of the macular. Our Peek Retina Camera app automatically optimises your phone’s camera settings for use with Peek Retina to make it easier for you to capture good quality fundus images. Unfortunately, the app does not work on all phones. We have optimised development on those phones most often in use in diabetic retinopathy screening programs. Once the functionality is proven we will strive to develop for more phones. We have also published the manual adjustments people can make if they wish.
