Abstract: The Optic Disc (OD) is a vital component of human retina, serving as the origin point for blood vessels. In standard retinal images, the OD becomes visible as a circular, bright yellowish region. Accurate localization of the optic disc (OD) in RGB retinal fundus images is essential for retina image analysis and assists in evaluating the severity of retinal diseases. However, identifying the OD precisely is challenging due to various factors, such as the presence of lesions near the OD and variations in its size, shape, and color. This review paper introduces the OD and highlights some of its key properties. Additionally, it provides a literature survey on OD detection and examines the challenges associated with this task. However, accurately identifying the optic disc (OD) poses challenges due to factors like nearby lesions and variations in its size, shape, and color.
