The Kay Amblyopia Tracker app lets eye professionals offer their patients a way to better understand and collaborate in their amblyopia journey by monitoring vision changes at home between eye test appointments. The app can only be accessed through a qualified eye professional, ensuring that a diagnosis and treatment plan are in place and ongoing. The test is simple and quick to do without any expertise. Once you’ve read the tutorial, just follow the on-screen instructions. The app displays the same letters and familiar pictures seen in a professional vision test, but with a unique testing process that is easy to use at home for children from 24 months of age. Regular home test scores are uploaded to a chart, making it easy to follow the child’s progress and giving useful feedback and encouragement Sharing the child’s progress chart with their eye professional could help to reduce the frequency of clinic appointments, so saving the time and costs. For patients: - Provides a fun, easy way to keep track of changes and improvements in your child’s amblyopia at home. - Gives you and your child a visual chart of their progress to encourage compliance with treatment. - Displays contact details for your child’s eye professional and an email link to them from the Test History Chart. - Tells you when you last tested and can be set to remind you when to test next. For eye professionals: - The app is configured to accurately display letter and picture optotypes that are validated for visual acuity measurement. - However, the scores given are not a visual acuity measurement, so ensuring no comparisons or treatment decisions are taken by the patient. - Access to the app test process is via activation codes provided only to qualified eye professionals and medical personnel. - Regular home testing and monitoring can aid patient understanding and compliance with treatment. - The progress chart can be shared with you, which may, in time, help you to decide on the frequency of follow up appointments. * Reference O’Connor, A., Waters, M., England, L., Milling, A. and Kay, H., 2021.
