The incidence of diabetic retinopathy globally calls for advanced and more universally applicable computer-aided diagnosis (CAD) systems. This survey paper explores the current state vision-based CAD techniques detection classification retinopathy, a diabetes-induced eye disorder that can lead to severe visual impairment or blindness. Characterized by variety manifestations including microaneurysms, exudates, hemorrhages, macular detachment, presents substantial challenges automated detection. is primarily due heterogeneity retinal fundus images, which display diverse spatiotextural features intricate vascular structures. Our exhaustive review indicates most existing methodologies predominantly concentrate on isolated types, employing localized feature analysis classification. Such specificity often results in limited accuracy generalizability, restricting practical real-world application. Furthermore, contemporary leading methods generally focus single characteristics, necessitating patients undergo multiple procedures, thereby increasing time, costs, possibly intensifying complexities. To overcome these obstacles, we propose adoption multi-trait-driven solutions. Utilizing potent capabilities deep learning, solutions could employ high-dimensional, multi-cue sensitive extraction ensemble learning approach designed improve generalizability dependability systems, offering holistic solution capable effectively managing retinopathy. study highlights need fundamental transformation motivating further research towards robust, multi-modal enhance detection, classification, grading this widespread ailment.
