Lights and Shadows on Artificial Intelligence in Glaucoma: Transforming Screening, Monitoring, and Prognosis
Executive Impact: AI in Glaucoma Management
Artificial intelligence (AI) is rapidly integrating into ophthalmology, particularly for glaucoma. This analysis explores how AI-driven tools, utilizing fundus images, OCT scans, and visual field tests, are transforming glaucoma diagnosis, monitoring, and prognosis. While promising for accuracy, efficiency, and access to care, challenges such as data limitations and bias persist. The review emphasizes the ongoing need for ophthalmologist oversight in AI development and validation.

Fundus Photographs and AI
AI, particularly deep learning (DL) algorithms, is highly effective in categorizing fundus images as glaucomatous or non-glaucomatous. This involves locating the optic nerve head (ONH) using intrinsic characteristics, vascular information, or both. Automated segmentation of the optic disc and excavation contours significantly improves the detection and monitoring of glaucoma progression, essential for early intervention.
Visual Field Test and AI
Visual field (VF) testing is the gold standard for glaucoma diagnosis and monitoring. AI-based methods, including CNNs, variational autoencoders, and recurrent neural networks (RNNs), are developed to classify, stage, and predict glaucomatous VF loss. These approaches analyze complex VF data over time to identify characteristic patterns and predict future VF progression, often earlier than traditional methods.
Optical Coherence Tomography and AI
Optical Coherence Tomography (OCT) provides objective analysis of structural damage in glaucoma. AI algorithms enhance OCT image quality, remove artifacts, and segment retinal vessels, improving detection of glaucomatous optic neuropathy (GON). OCT Angiography (OCT-A) combined with AI helps detect vascular-related changes and predict future VF progression.
AI Combined Approach in Glaucoma Diagnosis
Predicting glaucoma progression requires integrating multimodal data. AI models like FusionNet combine fundus photographs, OCT volumes, and visual field data to segment ONH and cup boundaries, and predict progression. This approach leverages complementary information from different diagnostic tools to improve accuracy and provide more personalized treatment strategies.

Personalized Treatment & Monitoring
| Feature | AI-Based Methods | Traditional Methods |
|---|---|---|
| Detection Speed | Automated, rapid analysis of large datasets. | Time-consuming manual inspection by specialists. |
| Diagnostic Accuracy | High sensitivity and specificity, often surpassing human experts. | Subjective, reliant on physician expertise, inter-observer variability. |
| Early Glaucoma Detection | Identifies subtle changes before functional deficits, years earlier. | Often detects changes only when functional deficits are evident. |
| Resource Intensity | Automates routine tasks, cost-effective for large-scale screening. | Resource-intensive, impractical for population screening. |
Tele-Glaucoma Service via AI
A systematic review of 45 studies demonstrated that AI-powered tele-glaucoma services achieved a diagnostic sensitivity of 83.2% and specificity of 79%. This approach, utilizing stereoscopic digital imaging, enabled detection rates higher than traditional in-person examinations, proving particularly beneficial for remote and underserved populations.
