• Abstract: Ocular diseases, ranging from diabetic retinopathy to glaucoma, present a significant public health challenge due to their prevalence and potential for causing vision impairment. Early and accurate diagnosis is crucial for effective treatment and management.In recent years, deep learning models have emerged as powerful tools for analysing medical images, including ocular imaging . However, challenges persist in model interpretability and uncertainty estimation, which are critical for clinical decision-making. This study introduces a novel application of GFlowOut, leveraging the probabilistic framework of Generative Flow Networks (GFlowNets) to learn the posterior distribution over dropout masks, for the classification and analysis of ocular diseases using eye fundus images. We develop a robust and generalizable method that utilizes GFlowOut integrated with ResNet18 and ViT models as backbone in identifying various ocular conditions. This study employs a unique set of dropout masks - none, random, bottomup, and topdown - to enhance model performance in analyzing ocular images. Our results demonstrate that the bottomup GFlowOut mask significantly improves accuracy, outperforming the traditional dropout approach.

  Glaucoma is a leading cause of irreversible blindness worldwide. Deep learning approaches using fundus images have largely improved early diagnosis of glaucoma. Variations in images from different devices and locations (known as domain shifts) challenge the use of pre-trained models in real-world settings. We propose a novel Graph-guided Test-Time Adaptation framework to generalize glaucoma diagnosis models to unseen test environments.

  glaucoma is challenging to detect since it remains asymptomatic until the symptoms are severe. Early identification of glaucoma is generally made based on functional, structural, and clinical assessments. Deep learning methods have partially solved this dilemma by bypassing the marker identification stage and analyzing high-level information directly to classify the data.

  Retinopathy of Prematurity (ROP) is an eye disorder primarily affecting premature infants with lower weights. It causes proliferation of vessels in the retina and could result in vision loss and, eventually, retinal detachment, leading to blindness. In recent years, there has been a significant effort to automate the diagnosis using deep learning. This paper builds upon the success of previous models and develops a novel architecture, which combines object segmentation and convolutional neural networks (CNN) Our proposed system first trains an object segmentation model to identify the demarcation line at a pixel level and adds the resulting mask as an additional "color" channel in
