Convolutional Neural Networks (CNNs) are the most common type of DL model used for processing OCT images in glaucoma diagnosis. They excel in segmenting retinal layers and detecting glaucomatous damage. Ran et al. achieved an AUROC of 0.969 and accuracy of 91% in identifying glaucomatous optic neuropathy.

Recurrent Neural Networks (RNNs) are effective for analyzing sequential OCT scans over time to track changes in ONH and RNFL, crucial for monitoring glaucoma progression. Ashtari-Majlan et al. used a spatial-aware transformer-GRU framework, achieving an F1 score of 93.58% and AUC of 95.24%. Gheisari et al. combined CNNs with RNNs to enhance glaucoma detection, achieving an F-measure of 96.2% compared to 79.2% for standalone CNNs, highlighting the utility of dynamic analysis.

| Diagnostic Accuracy | Enhanced: Integrates temporal dynamics for improved understanding. | Good: Detects spatial features effectively, but misses temporal context. |
Generative Adversarial Networks (GANs) enhance image quality and data augmentation by synthesizing OCT images, increasing depth for training DL models. Lazaridis et al. leveraged GANs to transfer TD-OCT images to SD-OCT quality, boosting statistical robustness for clinical trials. Synthetic data has shown comparable diagnostic performance to real images (AUC 0.97 vs 0.96).

Autoencoders facilitate advanced feature extraction and dimensionality reduction from OCT images, isolating critical features for diagnostic accuracy. Shon et al. used variational autoencoders to identify latent variables in AS-OCT images, distinguishing PACG eyes (P=0.015). Bowd et al. achieved 90% sensitivity for progression detection, significantly higher than traditional methods.

Large Language Models (LLMs) like GPT-4 and Gemini Pro offer multimodal data integration, processing both text and visual data. While promising for vitreoretinal diseases and macular diseases diagnosis, current models show limitations in complex, open-ended medical scenarios, with Gemini Pro achieving 10.7% F1 score for feature detection but higher concordance for referrals.
LLMs in Ocular Diagnostics: GPT-4 & Gemini Pro
Recent studies explored the application of multimodal LLMs in ophthalmology. GPT-4 showed potential in diagnosing vitreoretinal diseases using textual and OCT images, though accuracy was limited in complex cases. Gemini Pro VLM achieved an F1 score of 10.7% for feature detection in macular diseases but demonstrated high internal concordance (96-98%) for referral and treatment recommendations. These early results highlight the need for further refinement but underscore the potential for integrating diverse data types for comprehensive assessments.
Key Takeaway: LLMs present a novel approach to integrate visual and textual patient data, offering comprehensive diagnostic potential. However, current limitations in complex diagnoses require further development and rigorous validation before widespread clinical adoption.
