Prediction Model of Treatment Efficacy for Age-related Macular Degeneration Based on Multi-source Imaging Modalities

Sponsor: Beijing Hospital

Summary

Age-related macular degeneration (AMD) is one of the main causes of blindness in the elderly population. Intraocular injection of anti-VEGF drugs for neovascular AMD (nAMD) is the main treatment method at present. However, patients have different responses to anti-VEGF therapy, and some patients do not respond well to short - and long-term treatment. In this study, a retrospective study was adopted to collate and analyze the clinical data and imaging data of nAMD in the past, and to extract the imaging features from the multimodal modalities before and after treatment for deep learning, and to evaluate and quantify the clinical features, and to construct two multi-source feature models for predicting the short-term and long-term prognosis of nAMD patients. By verifying the accuracy of the model to predict the curative effect, the classification efficiency of the above characteristic models was compared, and the optimal model was selected. Its clinical application value was evaluated by calibration curve and decision curve. In addition, patients with poor treatment response in the study cohort were retrospectively analyzed, and the efficacy and safety of the combination of other treatment options in the actual clinic were analyzed. The purpose of this study is to provide scientific basis for early prediction, dynamic monitoring and optimization of overall treatment strategies for nAMD.
