A Survey on Diabetic Retinopathy Diagnosis by Automated Detection of Microaneurysm

Chronic hyperglycemia is caused by diabetes, which causes a chain reaction of molecular processes that results in microvascular damage. Microvascular problems like diabetic retinopathy are the leading cause of diabetic blindness. A person with chronic hyperglycemia must have regular eye exams to ensure they are not developing any eye problems. When diabetes is poorly managed, the retinal vasculature is affected by metabolic changes and altered hemodynamics, resulting in persistent hypoxia. Because the retina is a metabolically active tissue that requires adequate oxygenation, efforts are being made to combat retinal hypoxia via mechanisms such as the overexpression of the VEGF protein. In the end, the pathological processes of NPDR: retinal capillary microaneurysms, vascular permeability, and capillary closure, are the outcome of these fruitless attempts. Here, we have summarized some of the most recent published research on Diabetic Retinopathy Diagnosis by Automated Detection of Microaneurysm (DRD).
