Diabetic retinopathy (DR) is one of the leading causes of preventable blindness. This is rampant in people across the globe. Detecting it is a time-consuming and manual process. This experiment aims to automate the preliminary DR detection based on the retinal image of a patient's eye Digital Retinal Screening Programs: Systematic programs for the early detection of eye disease including diabetic retinopathy are becoming more common, such as in the UK, where all people with diabetes are offered retinal screening at least annually. This involves digital image capture and transmission of the images to a digital reading center. Diabetic retinopathy is a disease in which the blood vessels in the retina (which is located in the back of the eye) are weakened due to an imbalance in your blood sugar. This imbalance and weakening is caused by uncontrolled diabetes and it can result in blood and other fluids leaking into the eye, resulting in difficulty with vision and even. Combining Fine- and Coarse-Grained Classifiers for Diabetic Retinopathy Detection. Visual artefacts of early diabetic retinopathy in retinal fundus images are usually small in size, inconspicuous, and scattered all over retina. Detecting diabetic retinopathy requires physicians to look at the whole image and fixate on some specific regions to. Diabetic retinopathy (DR) leads to irreversible vision loss.
