Computerized Approaches for Retinal Microaneurysm Detection

The number of diabetic patients throughout the world is increasing with a very high rate. The patients suffering from long term diabetes have a very high risk of generating retinal disorder called Diabetic Retinopathy(DR). The disease is a complication of diabetes and may results in irreversible blindness to the patient. Early diagnosis and routine checkups by expert ophthalmologist possibly prevent the vision loss. But the number of people to be screen exceeds the number of experts, especially in rural areas. Thus the computerized screening systems are needed which will accurately screen the large amount of population and identify healthy and diseased people. Thus the workload on experts is reduced significantly. Microaneurysms(MA) are first recognizable signs of DR. Thus early detection of DR requires accurate detection of Microaneurysms. Computerized diagnosis insures reliable and accurate detection of MA's. The paper overviews the approaches for computerized detection of retinal Microaneurysms
