A General Overview of Retinal Lesion Detecting Devices

Many diseases cause harm to the human eye. Diabetic retinopathy could be one of the eye diseases, and the essential blindness reason, the lesions in the eye cause blood vessels that lead for blindness. The examination of the retina help in reduces the effect of disease on eye. In addition, diabetic patients regularly have to take a digital image for Retina. Then they are evaluated by skilled, which takes a long time and costs a lot of money due to the vast diabetic population. Then they are evaluated by skilled, which takes a long time and costs a lot of money due to the vast diabetic population. So, this field of study is vital and has the benefit of introducing systems for detection to decrease in an automated way. This work provides a brief overview of algorithms and devices for detecting exudates in the retina in an automated way. A device is designed to aid the auto-detection and grading of these diseases since the computer can expedite the test and correct the diagnosis. Using ocular imaging equipment to implement active data acquisition, nowadays, digital fundus pictures and optical coherence tomography (OCT) images are diagnosed as Diabetic Retinopathy (DR). To attain sufficient image quality for clinical diagnosis, most of the presently available fundus cameras and optical OCT instruments require the assistance of a professional operator.
