Analysis of the Deep Learning Method in Identifying Diabetic Retinopathy through the Retinal Fundus Image

Diabetic Retinopathy (DR) is a serious disease that affects the retina and is one of the main causes of blindness, especially in individuals with diabetes. This disease can continue without visible symptoms, but can cause severe damage to vision if not treated. Eye specialists use various tools, including optical coherence tomography (OCT) and retinal fundus images, to assess the thickness of the retina, structure, and detect the presence of edema, bleeding, and scars in the retina. Early detection and diagnosis of DR are crucial to prevent vision loss and blindness.

The Role of Deep Learning in Medical Imaging

In the era of modern technology, the use of Deep Learning models is increasing, especially in the medical field. This model is able to analyze OCT or Fundus images, extract unique features that exist in each stage of diabetic retinopathy, then identify the image to determine the stage of the disease. Deep Learning models have shown great potential in medical imaging, including the detection of diabetic retinopathy.

The research process begins with the image processing stage which includes several important steps. First, the selection of green channels is carried out to clarify the details on the fundus image. Furthermore, the contrast limited adaptive histogram Equalization (CLAHE) is applied to increase image contrast, so that important features can be more easily recognized. The process of morphological close and background exclusion is then carried out to eliminate noise and focus on relevant areas in the image.

Image Segmentation and Feature Extraction

After the processing stage, segmentation is carried out to produce binary images using thresholding techniques. This binary image functions as training data, which is then processed using the CNN algorithm. The training process was carried out as many as 30 EPOCH to ensure the model reached optimal accuracy.

After conducting a series of testing, the Deep Learning method with the CNN algorithm shows very promising results. The accuracy achieved in the identification of diabetic retinopathy based on the image of the retina fundus reaches 95.355%. These results indicate that the deep learning approach, especially CNN, has great potential to be used in the initial diagnosis and handling diabetic retinopathy.

The use of the Deep Learning method in identifying diabetic retinopathy through the retinal fundus image not only increases the accuracy of detection, but also provides a more efficient approach in handling this disease. This is very important given the serious impact that can be caused by diabetic retinopathy if not diagnosed early. By integrating this technology in clinical practice, it is expected to reduce blindness due to diabetes and provide better care for patients.

The application of advanced technology such as deep learning in the health sector is a significant advanced step, opening new opportunities to improve the quality of diagnosis and care, and provide new hope for diabetics to prevent the adverse effects of diabetes retinopathy. Future research should focus on the development of more accurate and efficient deep learning models, as well as the integration of this technology with other medical imaging modalities.

Despite the promising results, there are several limitations and challenges that need to be addressed. First, the availability of high-quality retinal fundus images is a major challenge. Additionally, the development of deep learning models requires a large amount of data, which can be time-consuming and expensive to collect. Furthermore, the interpretation of results requires expertise in both medicine and computer science.

In conclusion, the use of the Deep Learning method in identifying diabetic retinopathy through the retinal fundus image has shown great potential in improving the accuracy of detection and providing a more efficient approach in handling this disease. Future research should focus on the development of more accurate and efficient deep learning models, as well as the integration of this technology with other medical imaging modalities.
