This 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 10th October 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. AIMSO_ST_ABSPrimary ObjectiveC_ST_ABSO_LITo develop a mathematical model (or in silico model) 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). C_LI Secondary objectivesO_LITo apply deep learning models in combination with in silico models of blood flow to OCTA analysis, to confirm diagnosis of nAMD and its clinical subtypes. C_LIO_LITo develop prognostic models to predict treatment outcome based on longitudinal patient follow-up. C_LIO_LIUsing in silico simulations, to understand why certain patients do not respond optimally to anti-VEGF treatment. C_LIO_LITo define and simulate individualised anti-VEGF treatment for optimal response. C_LI OUTCOME MEASURESA validated in silico model of patient response to nAMD and anti-VEGF treatments tailored to individual patients using OCTA scans. O_LIIdentify optimal intravitreal anti-VEGF therapy drug regime for individual patients using in silico models C_LIO_LIImprove on the classification and characterisation of neovascular AMD into its subtypes C_LIO_LIPredict risk factors for poor treatment outcomes such as retinal vascular topology C_LI POPULATION 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 months Clinical QueriesClinical queries should be directed to Dr Savita Madhusudhan who will re-direct the query to the appropriate person if necessary.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
