“…Of the GAN models used in this study, RegGAN showed the best performance in predicting residual fluid. This result is in accordance with a previous study by Lui et al 15 We hypothesize that this is due to the more refined structure of the RegGAN model compared to the others. RegGAN has been updated from CycleGAN so that the generator is trained with an additional registration network to fit the misaligned noise distribution adaptively.…”

“…Lui et al compared the performances of several GAN models for the prediction of OCT appearance 1-month after an uncontrolled anti-VEGF treatment. 15 They reported that 92% of the images were difficult to differentiate from the real OCT images by retinal specialists, which was similar in the present study.…”

“…An MAE of 26.74 ± 21.28 µm compared to the real image (327.67 ± 209.11 µm, 8.16% difference) was observed for central macular thickness (CMT) in the study by Liu et al 15 It is unclear how they measured CMT in that study. As the present study utilized one central B-scan from the volume scan, the retinal area was calculated instead of the central subfield macular thickness.…”

“…You et al [32] conducted a survey analyzing the use of GANs in ophthalmology, covering a range of tasks and identifying key challenges. Shaopeng Liu et al [33] assessed six GAN models for predicting diabetic macular edema response to anti-VEGF therapy with OCT images, identifying RegGAN as the most precise in replicating post-treatment results. Furthermore, Xiaojun Yu et al [34] developed MDR-GAN, a generative adversarial network incorporating multi-scale and dilated convolution res-network for OCT retinal image despeckling, demonstrating superior denoising performance compared to existing methods.…”

This study investigates the effectiveness of using conditional generative adversarial networks (CGAN) to synthesize Optical Coherence Tomography (OCT) images for medical diagnosis. Specifically, the CGAN model is trained to generate images representing various eye conditions, including normal retina, vitreous warts (DRUSEN), choroidal neovascularization (CNV), and diabetic macular edema (DME), creating a dataset of 102,400 synthetic images per condition. The quality of these images is evaluated using two methods. First, 18 transfer-learning neural networks (including AlexNet, VGGNet16, GoogleNet) assess image quality through model-scoring metrics, resulting in an accuracy rate of 97.4% to 99.9% and an F1 Score of 95.3% to 100% across conditions. Second, interpretative analysis techniques (GRAD-CAM, occlusion sensitivity, LIME) compare the decision score distribution of real and synthetic images, further validating the CGAN network’s performance. The results indicate that CGAN-generated OCT images closely resemble real images and could significantly contribute to medical datasets.

Background Type 1 diabetes (T1D) simulators, crucial for advancing diabetes treatments, often fall short of capturing the entire complexity of the glucose-insulin system due to the imprecise approximation of the physiological models. This study introduces a simulation approach employing a conditional deep generative model. The aim is to overcome the limitations of existing T1D simulators by synthesizing virtual patients that more accurately represent the entire glucose-insulin system physiology. Methods Our methodology utilizes a sequence-to-sequence generative adversarial network to simulate virtual T1D patients causally. Causality is embedded in the model by introducing shifted input-output pairs during training, with a 90-min shift capturing the impact of input insulin and carbohydrates on blood glucose. To validate our approach, we train and evaluate the model using three distinct datasets, each consisting of 27, 12, and 10 T1D patients, respectively. In addition, we subject the trained model to further validation for closed-loop therapy, employing a state-of-the-art controller. Results The generated patients display statistical similarity to real patients when evaluated on the time-in-range results for each of the standard blood glucose ranges in T1D management along with means and variability outcomes. When tested for causality, authentic causal links are identified between the insulin, carbohydrates, and blood glucose levels of the virtual patients. The trained generative model demonstrates behaviours that are closer to reality compared to conventional T1D simulators when subjected to closed-loop insulin therapy using a state-of-the-art controller. Conclusions These results highlight our approach’s capability to accurately capture physiological dynamics and establish genuine causal relationships, holding promise for enhancing the development and evaluation of therapies in diabetes.
