Abstract :

One of the common causes of visionloss and blindness in patients with diabetes is Diabetic Retinopathy.The damage to the retina of human eye caused by the complication of increase in blood glucose level consequently leading to blindness is termed as Diabetic retinopathy. The longer the patient has diabetes the higher the chance of developing diabetic retinopathy [1].No specific symptoms are seen in DR patients until the illness is at the final stage. Thus , prior detection and timely treatment has to be ensured. Dark lesions such as Microaneurysms and Hemorrhages or bright lesions like Exudates are the visible symotoms of Diabetic Retinopathy [3]. Microaneurysms are reddish in color with a diameter less than 125 μm,which turn into hemorrhages at a later stage [6]. Conventionally , An ophthalmologist visualizes the blood vessels of the patient’s brain using an ophthalmoscope . This method is often time consuming and requires fluorescein angiograms for precise diagnosis. Moreover , it also requires highly trained and skilled clinicians to perform the DR severity grading technique. Tis paper presents a low cost retinal algorithm for detecting microaneurysms and hemorrhages which will assist opthalmologists across the globe in timely detection of diabetic retinopathy.
