Binary Classification: CSCR vs. Non-CSCR
This task focuses on distinguishing between CSCR vs. non-CSCR, Subretinal Detachment (SRD) vs. non-SRD, and macula-off SRD vs. macula-on SRD. Deep learning models, particularly DenseNet architectures applied to OCT images, have achieved exceptional accuracy (99.78%), sensitivity (99.68%), and specificity (100%).
Multiclass Classification: CSCR Subtypes
This section differentiates among non-CSCR, acute CSCR, and chronic CSCR, further sub-classifying chronic forms. Large datasets from hospitals like Hangil Eye Hospital enable high subtype accuracy with custom CNN architectures (97%). Modular pipelines combining deep learning and statistical classifiers also improve accuracy (94.2%).
Segmentation: Lesion Delineation
Segmentation precisely delineates lesions like Subretinal Fluid (SRF), Pigment Epithelial Detachment (PED), and RPE atrophy in retinal images. U-Net variants, Capsule Networks, and Attention Gate Networks (AGN) on OCT B-scans achieve high Dice coefficients (up to 0.965), improving spatial accuracy for small lesions and adaptability for heterogeneous clinical datasets.
Differential Diagnosis: CSCR vs. Other Retinal Diseases
This task aims to differentiate CSCR from conditions like AMD, PCV, and DME, and detect complications such as Choroidal Neovascularization (CNV). Multimodal imaging with FFA and OCT, combined with pre-trained CNNs and Vision Transformers, yields superior diagnostic performance, with AUCs up to 0.999.
Prognosis: Disease Trajectory & Treatment Response
Prognosis involves predicting disease recurrence, treatment efficacy (e.g., SRF absorption post-PDT), and long-term progression. Fusion models like DeepPDT-Net, combining ResNet-50 with XGBoost, achieve high accuracy (86.4%) and AUC (0.917) by integrating imaging and clinical data. Layer-specific OCT analysis further enhances precision.

Challenges in Clinical Adoption of Deep Learning for CSCR
Despite advanced performance, deep learning models for CSCR face significant hurdles for clinical integration. Key challenges include scarce and imbalanced datasets (e.g., SRF/non-SRF ratio of 1:8), a lack of open-access datasets and models, and inherent risks of overfitting due to limited data. Furthermore, there is insufficient external validation across diverse populations and imaging protocols, which limits generalizability and real-world applicability. Emerging approaches like few-shot learning and diffusion models show promise in mitigating data constraints, but improving dataset quality and rigorous cross-institutional validation remain critical for deployment.
