Bottom Line
This narrative review examines deep learning applications in optical microscopy, highlighting potential benefits for image enhancement, classification, and analysis. While the topic is highly relevant to modern biomedical research, the review lacks systematic methodology, making it unsuitable for evidence-based practice recommendations. The authors acknowledge important challenges including data requirements, model interpretability, and potential biases. For Australian healthcare professionals, this represents an emerging technology area requiring careful evaluation before clinical implementation. The review serves as an introductory overview but should not guide practice decisions without supporting systematic evidence. Clinicians interested in this field should seek more rigorous systematic reviews and primary research before adopting deep learning approaches in diagnostic or research applications.

Abstract
Optical microscopy is a cornerstone imaging technique in biomedical research, enabling visualization of subcellular structures beyond the resolution limit of the human eye. However, conventional optical microscopy faces challenges such as optical aberrations, diffraction-limited resolution, low signal-to-noise ratio (SNR), and poor contrast. The exponential growth of bioimaging data further underscores the need for advanced computational tools. Deep learning (DL) is a subset of machine learning that has emerged as a transformative approach to address these limitations, offering enhanced precision, reduced manual intervention, and diminished reliance on domain-specific expertise for image reconstruction, enhancement, and analysis. This review explores the integration of DL into optical microscopy, focusing on key applications including image classification, segmentation, and computational reconstruction. We examine prominent DL architectures such as convolutional neural networks (CNNs), U-Nets, residual networks (ResNets), and generative adversarial networks (GANs)-and their role in advancing diverse microscopy modalities. These frameworks enhance image quality, improve quantitative analysis, and democratize access to high-performance microscopy. Additionally, we discuss persisting challenges, including the demand for large, annotated datasets, dynamic sample variability, model interpretability, and potential data biases. Collectively, DL is poised to revolutionize optical microscopy, shaping its future developments in biomedical imaging.
