The study identifies several limitations and areas for improvement. Firstly, the current version of the web-based system is not yet ready for real-time assessment in hospitals. The researchers are working on an improved system that can accept unstructured and multimodal data, which is crucial for predicting eye diseases. Secondly, the system lacks user login or account security functions, which will be improved in future updates. Thirdly, the system does not have whole dynamic analyses, such as an interactive decision tree, which will be incorporated in subsequent versions to enhance communication between medical staff and patients. Additionally, the study acknowledges that more clustering algorithms will be implemented to improve the robustness and reliability of prediction results. Lastly, while the current system evaluates three chronic diseases, more chronic disease prediction models, such as for coronary artery disease, will be added in the future.
