| Abstract | Retinal diseases such as age-related macular disorders, diabetic retinopathy [1], and glaucoma areprogressive eye conditions that remain among the leading causes of preventable blindness worldwide.Initial detection and correct classification of these disorders are essential for timely treatment and visionpreservation. Now a days, deep learning has emerged as a transformative approach for analysing retinalfundus images, offering high accuracy and efficiency in automated diagnosis and grading [1, 6]. Thissurvey explores the latest advancements in DL-based classification of multiple retinal diseases, focusingon key architectures such as CNNs, RNNs, DBNs, and autoencoders [4, 15]. It also reviews widely usedpublic datasets such as EyePACS, APTOS 2019, and MESSIDOR [16], and discusses pre-processingtechniques including image enhancement, de-noising, and data augmentation [12, 13]. Furthermore, thepaper highlights the role of transfer learning and hybrid models in improving performance when labelledmedical data is limited [5, 7]. Challenges such as data imbalance, lack of image quality, and ethicalfactor in clinical adoption are addressed. Finally, future directions are outlined, including thedevelopment of lightweight models for mobile deployment [1], improved dataset diversity [13, 16], andstronger collaboration between AI researchers and healthcare professionals to reduce the gap between research and real-world healthcare applications. |
