In the context of an increasing need for clinical assessments of foundation models, we developed EyeFM, a multimodal vision-language eyecare copilot, and conducted a multifaceted evaluation, including retrospective validations, multicountry efficacy validation as a clinical copilot and a double-masked randomized controlled trial (RCT). EyeFM was pretrained on 14.5 million ocular images from five imaging modalities paired with clinical texts from global, multiethnic datasets.

Researchers have utilized various imaging modalities, including slit beam, diffuse anterior segment, and retinal imaging, to develop deep learning (DL) algorithms for automated cataract analysis. However, the comparative performance of these algorithms across different ocular imaging modalities remains unevaluated, mainly due to the absence of standardized test sets across studies.

Medical phrase grounding is crucial for identifying relevant regions in medical images based on phrase queries, facilitating accurate image analysis and diagnosis. However, current methods rely on manual extraction of key phrases from medical reports, reducing efficiency and increasing the workload for clinicians. Additionally, the lack of model confidence estimation limits clinical trust and usability.

Importance: OpenAI's recent large language model (LLM) o1 has dedicated reasoning capabilities, but it remains untested in specialized medical fields like ophthalmology. Evaluating o1 in ophthalmology is crucial to determine whether its general reasoning can meet specialized needs or if domain-specific LLMs are warranted.
Objective: To assess the performance and reasoning ability of OpenAI's o1 compared with other LLMs on ophthalmological questions.

Importance: Timely disease diagnosis is challenging due to limited clinical availability and growing burdens. Although artificial intelligence (AI) has shown expert-level diagnostic accuracy, a lack of downstream accountability, including workflow integration, external validation, and further development, continues to hinder its clinical adoption.
Objective: To address gaps in the downstream accountability of medical AI through a case study on age-related macular degeneration (AMD) diagnosis and severity classification.
Purpose: To generate fundus photographs of multiple kinds of retinal disease, bypassing the requirement of coding technique.
Methods: The dataset contained fundus photographs of 10 categories of retinal conditions, with 500 fundus photographs in each category. We randomly divided the collected data into a training set (80%) and a test set (20%).
Objective: We aimed to examine the cross sectional and causal associations of grip strength with cataract, glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD) and probe the underlying mechanisms by evaluating the mediating role of metabolomic alterations.
Design: Cross sectional study.
Subjects: A total of 307 796 UK Biobank participants with grip strength and covariates data available.

Despite generative AI's enormous potential in medical report generation, automatic FFA interpretation lacks robust models and sufficient evaluation metrics. This study introduces InterpreFFA, a diagnosis-supervised contrastive learning framework, to emulate ophthalmologists' decision-making process in FFA report generation.

Systemic lupus erythematosus (SLE) is a serious autoimmune disorder predominantly affecting women. However, screening for SLE and related complications poses significant challenges globally, due to complex diagnostic criteria and public unawareness. Since SLE-related retinal involvement could provide insights into disease activity and severity, we develop a deep learning system (DeepSLE) to detect SLE and its retinal and kidney complications from retinal images.

Background: The global rise in myopia, particularly in Asia, presents significant public health challenges. Analyzing trends and forecasting impacts are critical for developing strategies to mitigate this burden.
Methods: We conducted the largest study to date on myopia and high myopia prevalence in Chinese children and adolescents aged 7-18 years, analyzing data from 5,095,256 individuals across 119 studies from 1998 to 2022.
Uncorrected refractive error is the leading cause of vision impairment in children globally, and studies have demonstrated that spectacle correction addresses the large majority of childhood vision impairment. Furthermore, trial evidence illustrates the beneficial impact of spectacles on learning, with effect sizes exceeding that of other school health interventions. While it is established that good vision is important for learning and optimising childhood development and quality of life, many countries lack healthcare systems that provide vision screening or universal access to eyecare for all citizens.
