Abstract

Artificial intelligence (AI) has emerged as a transformative force in modern medicine, with ophthalmology standing at the forefront of its clinical integration. Among ophthalmic disorders, glaucoma—a leading cause of irreversible blindness worldwide—presents unique opportunities and challenges for AI-based solutions due to its chronic, progressive nature and reliance on multimodal data, including structural and functional assessments. This review article offers a comprehensive synthesis of the current and emerging roles of AI in the detection, monitoring, and management of glaucoma. AI algorithms, particularly deep learning and machine learning models, have demonstrated exceptional capabilities in interpreting fundus photographs, optical coherence tomography (OCT) images, and visual field data to identify glaucomatous damage. These systems often approach or even exceed the diagnostic performance of human experts. Moreover, AI has shown significant promise in facilitating large-scale population-based screening, improving early detection rates, and addressing disparities in access to subspecialty care, particularly in low-resource and remote settings. In the monitoring of disease progression, AI tools are being developed to detect subtle structural or functional changes over time, predict future visual outcomes, and support more precise and individualized treatment decisions. Despite these advancements, the widespread clinical adoption of AI in glaucoma care faces several critical barriers. Key limitations include poor generalizability of models across diverse populations, imaging devices, and clinical settings; scarcity of well-annotated, high-quality, and demographically representative datasets; and a lack of transparency and interpretability in algorithmic decision-making—commonly referred to as the “black box” problem. Ethical concerns, regulatory uncertainty, integration challenges within existing healthcare infrastructures, and medico-legal accountability also require thoughtful resolution before AI can be reliably deployed in clinical practice. This review critically evaluates the strengths, limitations, and real-world potential of AI technologies in glaucoma. It provides clinicians, researchers, and healthcare policymakers with a balanced and up-to-date perspective, highlighting promising avenues for future research, including explainable AI, federated learning, multi-modal data integration, and longitudinal validation studies. By fostering a deeper understanding of both the opportunities and challenges associated with AI, this article aims to guide the responsible, equitable, and evidence-based integration of AI into comprehensive glaucoma care.

Abstract

Background: An Electrocardiogram is a non-invasive method for receiving heart signals. Despite advances in imaging methods, the electrocardiogram still plays an important role remains a vital tool in the diagnosis of heart diseases. Analysis of electrocardiogram signals plays an important role in the early detection of heart diseases such as arrhythmias and heart attacks. Today, with the advancement of science and technology, computer methods have received more and more attention from doctors. In this study, machine learning methods were used to classify normal and abnormal heartbeats.
Methods: The data under study were extracted from a dataset called Heartbeat published on the Kaggle website. This dataset includes samples of audio ECG signals that are divided into healthy and unhealthy categories. First, the data were preprocessed and normalized to prepare them for input into the model. Then, temporal and frequency features were extracted from the signals. Next, a hybrid model consisting of one-dimensional convolutional layers was designed and trained. Also, by using the early stopping method, overfitting was prevented and the stability of the model was improved.
Results: In this study, it was shown that by using deep learning, especially using CNN and 1D Conv, an accuracy of 0.99% and a loss of 0.0350 for test data in detecting normal and abnormal heartbeats can be achieved. This model has the ability to analyze complex structures and temporal dynamics of ECG signals and is able to detect patterns related to cardiac disorders.
Conclusion: Today, the electrocardiogram has received more attention than ever before. Appropriate selection of the model, data standardization, and a qualitative range of data are among the factors of high accuracy in this study. This study can be an effective step in the development of intelligent systems for diagnosing cardiac disorders and can be used in medical applications, especially in the field of continuous patient monitoring.
