AI and the Eye – Integrating deep learning andin silicosimulations to optimise diagnosis and treatment of wet macular degeneration

Abstract

AbstractThis protocol describes the A-EYE Study and provides information about procedures for entering participants. Every care was taken in its drafting, but corrections or amendments may be necessary. These will be circulated to investigators in the Study. Problems relating to this Study should be referred, in the first instance, to the Chief Investigator.This study will adhere to the principles outlined in the UK Policy Framework for Health and Social Care Research (v3.2 10thOctober 2017). It will be conducted in compliance with the protocol, the UK General Data Protection Regulation and Data Protection Act 2018, and other regulatory requirements as appropriate.DESIGNSingle centre non-interventional study of patients with age-related macular degeneration to develop computational models of disease prediction and treatment outcome involving analysis of macular OCTA scans.AIMSPrimary ObjectiveTo develop a mathematical model (orin silicomodel) of blood flow and anti-VEGF transport in the retina that, in combination with AI-based analysis of macular OCTA scans and clinical data, can be used to predict treatment response in patients with neovascular age-related macular degeneration (nAMD).Secondary objectivesTo apply deep learning models in combination within silicomodels of blood flow to OCTA analysis, to confirm diagnosis of nAMD and its clinical subtypes.To develop prognostic models to predict treatment outcome based on longitudinal patient follow-up.Usingin silicosimulations, to understand why certain patients do not respond optimally to anti-VEGF treatment.To define and simulate individualised anti-VEGF treatment for optimal response.OUTCOME MEASURESA validatedin silicomodel of patient response to nAMD and anti-VEGF treatments tailored to individual patients using OCTA scans.Identify optimal intravitreal anti-VEGF therapy drug regime for individual patients usingin silicomodelsImprove on the classification and characterisation of neovascular AMD into its subtypesPredict risk factors for poor treatment outcomes such as retinal vascular topologyPOPULATION ELIGIBILITYAll patients aged 55 years or more, with a new diagnosis of nAMD in at least one eye, attending the Macular Clinic at Royal Liverpool University Hospital, who have had a macular OCTA scan at baseline i.e. at the time of diagnosis.DURATION48 monthsClinical QueriesClinical queries should be directed to Dr Savita Madhusudhan who will re-direct the query to the appropriate person if necessary.SponsorThe University of Liverpool is the research Sponsor for this Study.
