Article Abstract
Aims: To evaluate the acceptability, applicability, and cost-utility of AI-powered portable fundus cameras for diabetic retinopathy (DR) screening in Hong Kong, providing a viable alternative screening solution for resource-limited areas.
Methods: This pragmatic trial conducted in an optometric clinic and two optical shops. A self-testing system was used, integrating a portable fundus camera and AI software that automatically identified DR. Three months following the screening, selected participants were invited to complete an open-ended questionnaire.
Results: A total of 316 subjects participated, with age of 60.80 ± 8.30 years. The success rate of the self-testing system without active assistance was 89 %. Among 61 subjects who completed follow-up interview, a majority agreed that the system and report were easy to follow and understand (85.3 % and 75.4 %). The satisfaction rate was 64 %, and the willingness to use again was 80 %. The AI screening showed a cost saving of 6312.92 USD per QALY, while the adjusted AI model saved 18639. AI screening and adjusted model outperformed traditional screening (Net Monetary Benefit 367,863.31 and 354,904.76 vs 339,919.83 USD).
Conclusions: The AI-powered portable fundus camera demonstrated high acceptability and applicability in real-world settings, suggesting that AI screening could be a viable alternative in resource-limited settings.

Introduction: Dry eye disease (DED) affects over 300 million people worldwide and continues to pose diagnostic challenges due to fluctuating symptoms and reliance on static, clinic-based tests. Conventional methods such as Schirmer's test and tear osmolarity provide only episodic insights, failing to capture the dynamic behavior of the tear film. Recently, biosensor-embedded wearable devices, including smart contact lenses, eyelid-mounted patches, and sensor-equipped spectacles, have emerged, enabling real-time and continuous tracking of tear metrics and blink patterns.

Introduction: Diabetic retinopathy (DR) detection is made easy with the use of a fundus camera. The evidence of the use of a fundus camera for DR detection in non-mydriatic conditions with limited technical challenges is scarce. This is a pilot study that evaluates the performance of the Oivi fundus camera (Oivi AS, Oslo, Norway), a novel non-mydriatic tabletop fundus camera for DR detection using a single-field, macula-centered imaging approach.

Purpose: Leveraging an artificial intelligence system (AI) for glaucoma screening can mitigate the current challenges and provide prompt detection and management crucial in averting irreversible blindness. The study reports the real-world performance of a glaucoma AI system deployed on a smartphone-based fundus camera across various severities of glaucoma.
Methods: In this prospective comparative study at a tertiary care glaucoma clinic, consecutive patients were evaluated by a glaucoma specialist using clinical assessment, visual field tests, and SD-OCT, and categorized as definite glaucoma, glaucoma suspect, or no glaucoma.

Introduction: A shortage of trained retinal specialists has created a growing need for a telehealth retinal screening alternative. Recent developments in handheld fundus cameras, enhanced by artificial intelligence (AI) and machine learning (ML) methods, have created a promising avenue to satisfy the unmet need for efficient retinal disease screening. This paper discusses the state of current handheld fundus cameras as well as promising future directions.
