Special Issue Information

Dear Colleagues,

Artificial intelligence (AI) applications in ophthalmology have emerged as transformative tools, reshaping various facets of eye care. Leveraging AI's capacity to analyze extensive datasets and interpret the intricate imaging, automated diagnosis and early detection of ocular diseases, including diabetic retinopathy and glaucoma, has become more precise. Machine learning algorithms exhibit exceptional accuracy in image analysis, facilitating swift and accurate diagnoses by clinicians. Furthermore, predictive modeling enhances prognosis and contributes to personalized treatment plans. The integration of AI not only streamlines clinical workflows and enhances efficiency, but also holds the promise in broadening access to eye care, especially in remote or underserved regions. Despite these promising advancements, numerous challenges and ethical concerns must be addressed before the safe deployment of AI in ophthalmic care.

Ensuring the validation of the quality and fairness of AI-generated outputs, safeguarding patient privacy and optimizing collaboration between AI and healthcare professionals are imperative for achieving optimal patient outcomes wherever AI tools are employed.

This Special Issue is dedicated to exploring advancements in the realm of AI applications within ophthalmology. We invite contributions that illustrate the diverse ways in which AI can positively impact various facets of eye care. Potential topics of interest include, but are not limited to:

• Anomaly detection in ophthalmic imaging;
• Bias/fairness of AI models in ophthalmology;
• Applications of diffusion /generative models in ophthalmology;
• Domain adaptation, domain generalization, data harmonization and transfer learning techniques;
• Federated learning techniques in ophthalmology;
• Few-shot learning techniques in ophthalmology;
• Interpretability of AI models in ophthalmology;
• Multi-modality AI models in ophthalmology;
• Applications of multi-task learning in ophthalmology;
• Out-of-distribution detection techniques in ophthalmology;
• Self-supervised learning applications in ophthalmology;
• Weakly supervised learning / multi-instance learning applications in ophthalmology
• Image registration of ophthalmic imaging;
• Uncertainty quantification of AI models in ophthalmology;
• Applications of medical phrase grounding/visual question answering/ChatGPT in ophthalmology.

Background/Objectives: Glaucoma is the leading cause of irreversible blindness, with a significant proportion of cases remaining undiagnosed globally. The interpretation of optic disc and retinal nerve fibre layer images poses challenges for optometrists and ophthalmologists, often leading to misdiagnosis. AI has the potential to improve diagnosis. This study aims to validate an AI system (a convolutional neural network based on the Inception-v3 architecture) for detecting glaucomatous optic neuropathy (GON) using colour fundus photographs from a UK population and to compare its performance against Australian optometrists. Methods: A retrospective external validation study was conducted, comparing AI’s performance with that of 11 AHPRA-registered optometrists in Australia on colour retinal photographs, evaluated against a reference (gold) standard established by a panel of glaucoma specialists. Statistical analyses were performed using sensitivity, specificity, and area under the receiver operating characteristic curve (AUROC). Results: For referable GON, the sensitivity of the AI (33.3% [95%CI: 32.4–34.3) was significantly lower than that of optometrists (65.1% [95%CI: 64.1–66.0]), p < 0.0001, although with significantly higher specificity (AI: 97.4% [95%CI: 97.0–97.7]; optometrists: 85.5% [95%CI: 84.8–86.2], p < 0.0001). The optometrists demonstrated significantly higher AUROC (0.753 [95%CI: 0.744–0.762]) compared to AI (0.654 [95%CI: 0.645–0.662], p < 0.0001). Conclusion: The AI system exhibited lower performance than optometrists in detecting referable glaucoma. Our findings suggest that while AI can serve as a screening tool, both AI and optometrists have suboptimal performance for the nuanced diagnosis of glaucoma using fundus photographs alone. Enhanced training with diverse populations for AI is essential for improving GON detection and addressing the significant challenge of undiagnosed cases. Full article

Background: The purpose of this study was to compare geographic atrophy (GA) area semi-automatic measurement using fundus autofluorescence (FAF) versus optical coherence tomography (OCT) annotation with the cRORA (complete retinal pigment epithelium and outer retinal atrophy) criteria. Methods: GA findings on FAF and OCT were semi-automatically annotated at a single time point in 36 pairs of FAF and OCT scans obtained from 36 eyes in 24 patients with dry age-related macular degeneration (AMD). The GA area, focality, perimeter, circularity, minimum and maximum Feret diameter, and minimum distance from the center were compared between FAF and OCT annotations. Results: The total GA area measured on OCT was 4.74 ± 3.80 mm2. In contrast, the total GA measured on FAF was 13.47 ± 8.64 mm2 (p < 0.0001), with a mean difference of 8.72 ± 6.35 mm2. Multivariate regression analysis revealed a significant correlation between the difference in area between OCT and FAF and the total baseline lesion perimeter and maximal lesion diameter measured on OCT (adjusted r2: 0.52; p < 0.0001) and the total baseline lesion area measured on FAF (adjusted r2: 0.83; p < 0.0001). Conclusions: We report that the GA area measured on FAF differs significantly from the GA area measured on OCT. Further research is warranted in order to determine the clinical relevance of these findings. Full article
