Diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness. So early detection of symptoms could help to avoid blindness. In this thesis, we present some experiments on some features of Diabetic Retinopathy like properties of exudates, properties of blood vessels and properties of microaneurysm. Using the features, we can classify healthy, mild non-proliferative, moderate non-proliferative, severe non-proliferative and proliferative stage of DR. Support Vector Machine, Random Forest and Naive Bayes classifiers are used to classify the stages. Finally, Random Forest is found to be the best for higher accuracy, sensitivity and specificity of 76.5%, 77.2% and 93.3% respectively.

International Journal of Advance Research and Innovative Ideas in Education, 2018 Diabetes Retinopathy is human eye affection.It can affect to retina of eye and causes blindness. Diabetes is supposed the one of the most deadliest disease nowadays. Most of the work in this field is based on disease detection or manual extraction of features, but this paper proposed automatic analysis of this disease into different stages using machine learning. This paper presents the preprocessing technique to remove the noise reduction and hence classify high resolution image into 3 stages based on severity by using (SVM,Navie Bayes and LR) algorithm This results clearly show that the advanced technique outperforms over the usable techniques in terms of sensitivity, accuracy and error rate.There are so many datasets are available publicly such as kaggle ,stare ,Drive. The International journal of analytical and experimental modal analysis The damage in the blood vessels of human eye in retina defines the disease known as Diabetic retinopathy (DR).The word "Retinopathy" is specified due to abrasion in the blood vessel of light-sensitive membrane of eye called "Retina". Diabetes Mellitus is a kind of disease that occurs in retina due to high sugar level in the blood and it is the root cause of Diabetic Retinopathy.As the blood cells circulate in retina, it blocks the blood vesselsand thus the blood supply is stopped. Therefore for nourishment of retina; the eye develops new blood vessels which is improper in growth and easily leads to leakagewhich can also lead to loss of vision.The major goal is automatically detect and classify the DR using appropriate algorithm by giving retinal image as an input.This paper specifies the related works on detection and classification of diabetic retinopathy under the domain machine learning. International Journal of Engineering Technology and Management Sciences, 2024 Diabetic Retinopathy (DR) is one of the major causes of blindness. DR mutilates the retinal blood vessels of a patient having diabetes. The DR has two major types: First one is Non-Proliferative Diabetic Retinopathy (NPDR) and second is Proliferative Diabetic Retinopathy (PDR). PDR is the advanced stage of DR which leads to neo vascularization, it is expected that the number of DR patients is to increase from 382 million to 592 million by 2028. In the early stages of the DR the patients were asymptomatic but in advanced stages, it leads to floaters, blurred vision, distortions, and progressive visual acuity loss. It is difficult but utmost important to detect the DR in early stages to avoid the worse effect of latter stages. The colour fundus images were used for the diagnosis of DR, the manual analysis could only be done by highly trained domain experts but it is bit expensive in terms of time and cost. Hence, it is important to use computer vision methods to automatically analyse the fundus images of Retina and assist the physicians/radiologists. The computer vision-based methods are divided into hand-on engineering and end-to-end learning. The hand-on engineering methods extract features using traditional approaches such as HoG, SIFT, LBP, Gabor filters, which failed to encode the variations in scale, rotation, and illumination. The end-to-end leaning automatically learns the hidden rich features and thus performs better classification. International Journal on Computer Science and Engineering, 2018 Diabetic Retinopathy is human eye disease which causes damage to retina of eye and it may eventually lead to complete blindness. Detection of diabetic retinopathy in early stage is essential to avoid complete blindness. Many physical tests like visual acuity test, pupil dilation, optical coherence tomography can be used to detect diabetic retinopathy but they are very time consuming and costly.There are many features present in retina but the exudates feature which is one of the primary signs of diabetic retinopathy and which is a main cause of blindness that could be prevented with the help of this automatic detection process. In feature extraction Pupil dilation is important step in the normal screening process but this affects Diabetes vision. The automatic detection process reduces examination time, and increase accuracy. In this paper we provide review on many techniques and algorithms that helps to diagnose Diabetic Retinopathy in retinal fundus images. This paper also reviews, classifies and compares the algorithms and techniques previously proposed in order to develop better and more effective algorithms. Diabetic retinopathy is the retinal abnormality for the diabetic patient due to imbalanced blood glucose level. To help the ophthalmologist in diagnosing the diabetic retinopathy using retinal images taken from various publicly available databases, efficient classifiers are used to analyze the images and to identify the symptoms of diabetic retinopathy such as microanueryms, hemorrhages, exudates, cotton wool spots etc. The manual screening method of diabetic retinopathy is time consuming and it is difficult for the ophthalmologist in producing accurate results. Thus an automatic computerized system is enabled to detect the diabetic retinopathy with less time consumption and obtain effective results. In this paper, a brief survey is presented on the various classification methods used in the detection of diabetic retinopathy. The various classifiers are efficient in classifying diabetic retinopathy as proliferative and non-proliferative diabetic retinopathy. The machine learning classifiers such as Naïve Bayes, Gaussian, random forest, support vector machine and neural network achieves the greater accuracy of more than 90%. Using these algorithms severity grading of the abnormalities is also improved. Journal of Engineering Research, 2021 Diabetic Retinopathy (DR) is the complicatedness of diabetes that happens due to macular degeneration among Type II diabetic patients. The early symptom of this disease is predicted through annual eye checkups. Hence, one can save their vision at an early stage. Later on, it prompts retinal detachment. There is a requirement for awareness among diabetic patients about this disease to prevent their life from vision misfortune. Along these lines, there is a need for a computer-assisted method to analyze the disease. The proposed system used Adaptive Histogram Equalization (AHE) technique for image enhancement, Hop Field Neural Network for blood vessel segmentation, and Adaptive Resonance Theory (ART) for blood vessel classification. The proposed system analyzes the disease and classifies the disease level effectively with high accuracy. Also, the system notifies the users about the stages of the disease. The proposed system is evaluated with the clinical as well as open fundus image d...

Therefore early medical diagnosis of diabetic retinopathy and it medical cure is essential to prevent the severe side effects of diabetic retinopathy. Manual detection of diabetic retinopathy by ophthalmologist take plenty of time and patients need to suffer a lot at this time. An automated system can help detect diabetic retinopathy quickly and we can easily follow-up treatment to avoid further effects to the eye. This study proposes a machine learning method for extracting three features like exudates, hemorrhages, and micro aneurysms and classification using hybrid classifier which is a combination of support vector machine, k nearest neighbour, random forest, logistic regression, multilayer perceptron network. From the results of the experiments, the highest accuracy values 82%. Hybrid approach produced a precision score of 0.8119,Recall score of 0.8116 and f-measure score of 0.8028.
