Cutting-edge tear fluid biomarker research
June 11 | 9 - 10:30am EDT
Organizer: Marlies Gijs, PhD, University Eye Clinic Maastricht, School for Mental Health and Neuroscience (MHeNs), Maastricht University Medical Center (MUMC+), Maastricht, The Netherlands
Tear fluid is emerging as a source of non-invasive biomarkers since tear fluid biomarkers are the only way to gather biological information about the eye (and the body) in real time. However, clinical applications of tear biomarkers are not there yet, as the field is facing a lack of standardization and harmonization. Accurate quantification of tear proteins can be improved by standardizing methods to collect and process tear fluid. During this Special Interest Group session, the following themes will be discussed: How to normalize your raw data into clinically meaningful biomarkers?; The need for reference values of commonly investigated tear biomarkers.; How to set up your own tear fluid biobank.; and the need for an open repository of tear proteomics.

Eye movements as a window to ophthalmic diagnostic decision-making
June 11 | 6 - 7:30pm EDT
Organizer: Kaveri A. Thakoor, PhD, Columbia University Irving Medical Center, NY, NY, USA
The goal of this significant interest group (SIG) is to launch awareness of the potential wealth of information embedded in the eye movements of expert ophthalmic clinicians as they view ophthalmic images for disease diagnoses. Such eye movements have the potential for aiding in understanding of mechanisms behind expert diagnostic decision-making (from a neuroscience perspective), for aiding in medical education/training, and for training of AI systems to perform with higher accuracy and interpretability (already has shown some promise in radiology). This SIG will include talks from an ophthalmology residency program director, a visual neuroscientist, and an AI-in-ophthalmology engineer who will share their newest initiatives and latest results toward using eye movements to inform multiple fields from visual neuroscience and AI to medical education. The target audience is everyone at ARVO from ophthalmologists (the experts themselves) and ophthalmologists-in-training to AI engineers and visual neuroscientists – anyone interested in the role of eye movements in informing our understanding of medical-expert decision-making and how this information can be harnessed to help create more explainable automated diagnostic systems and more objective medical education.
Presentations
- Educational insights derived from resident vs. expert eye movements
Royce WS Chen, MD, Columbia University Irving Medical Center, NY, NY, USA
Eye movements of trainees vs. experts show significant differences in terms of quantity and location; these differences can serve to aid in medical education and quantification of skills progression in exciting new ways. - What small eye movements reveal about internal states
Susana Martinez-Conde, PhD, State University of New York, Downstate Health Sciences University, Brooklyn, NY, USA
To maintain our perception of a stable world, our oculomotor system must calibrate how much our eyes must move when we fixate. Too little movement can lead to visual fading, and too much motion to blurred and unstable vision. Central and peripheral pathologies can disturb this fine balance. Determining how normal fixation differs from pathological fixation has the potential to aid early and differential diagnosis of neurological and ophthalmic disease, as well as the quantification of its progression and response to treatment. - Creating an expert–AI team for eye disease detection driven by expert gaze data
Kaveri A. Thakoor, PhD, Columbia University Irving Medical Center, NY, NY, USA
We are using the power of Vision Transformers (built from the same natural language processing-inspired transformer backbone behind ‘ChatGPT’) to learn the eye movement trajectories of ophthalmologists as they view optical coherence tomography data. Just as transformers learn the grammar of a language, our models learn the ‘grammar’ of a clinician’s eye movement trajectory across OCT images, creating more accurate, efficient, and interpretable AI ‘teammates’ for medial experts in the ophthalmic clinic.
Unravelling the causes of reticular pseudodrusen in age-related macular degeneration: Genetics, stem-cell modelling and immune regulation
June 11 | 6 - 7:30pm EDT
Organizers: Carla J. Abbott, BOptom, PhD, Centre for Eye Research Australia, Royal Victorian Eye and Ear Hospital, Melbourne, Victoria, Australia; Robyn H. Guymer, MBBS, PhD, FRANZCO. Centre for Eye Research Australia, Royal Victorian Eye and Ear Hospital, Melbourne, Victoria, Australia
Reticular pseudodrusen (RPD; aka subretinal drusenoid deposits) are a critical age-related macular degeneration (AMD) phenotype, associated with a high risk of progression to sight-threatening late-stage disease. However, much is still unknown about their underlying cause, genetic associations and pathophysiology. The RPD Consortium was formed to solely investigate RPD and has combined and harmonized phenotyping and genotyping data from 15 international research groups for the purposes of conducting a meta-analysis of a genome-wide association study for RPD in the setting of AMD. Our group has also targeted key areas of basic research into improving our understanding of their pathogenesis and impact, through further deeply phenotyping patients, including generating stem cells from RPD patients, investigating immune regulation from RPD patients and deriving mouse models that recapitulate aspects of RPD biology. These disease models have the potential to improve our understanding of the cause of RPD and in doing so, identify novel therapeutic targets for treating AMD with coexistent RPD and prevention of vision loss from late-stage disease.
Presentations
- A genome-wide association study of reticular pseudodrusen in age-related macular degeneration
Samaneh Farashi, PhD, Walter and Eliza Hall Institute, University of Melbourne, Melbourne, Victoria, Australia.
Several genes known to associate with AMD are reportedly associated with RPD, including the ARMS2/HTRA1 loci, however, there are inconsistent findings. Revealing genetic risk factors of RPD is not straightforward given the difficulty of detecting RPD via standard clinical examination and color fundus photos. Our Reticular Pseudodrusen Consortium aims to obtain the largest cohort of well-phenotyped RPD and genotype data and perform a genome-wide association study (GWAS), to determine the genetic risk factors of RPD. The presentation will discuss the approach to the multi-cohort GWAS and post-GWAS analyses and advanced bioinformatics methods to tease out the genetic risk factors of RPD. - Using stem cells to help our understanding of reticular pseudodrusen
Alice Pébay, BSc (Psych), PhD, University of Melbourne, Melbourne, Victoria, Australia
A hallmark of age-related macular degeneration pathogenesis is the accumulation of drusen underneath the retinal pigment epithelium, a biological process also observable in vitro. The accumulation of drusen is able to predict the progression to advanced AMD, making accurate characterisation of drusen in vitro models valuable in disease modelling and drug development. Reticular pseudodrusen (RPD) deposits above the retinal pigment epithelium in the subretinal space is a critical AMD subtype that is high risk for AMD progression. The talk will describe a semi-automated pipeline for quantifying the presence of drusen-like deposits in vitro, using cultures derived from patient-specific induced pluripotent stem cells (iPSCs). High-throughput confocal microscopy and 3D reconstruction can be used to quantify the drusen-like deposits including location and composition and whether the deposits are on the apical or basal surface of the retinal pigment epithelial cells. The application of in vitro iPSC modelling in understanding AMD and RPD pathophysiology will be discussed. - The immune system and reticular pseudodrusen
Erica L. Fletcher, PhD, University of Melbourne, Melbourne, Victoria, Australia
Reticular pseudodrusen (RPD) are a risk factor for the progression of age-related macular degeneration, however the mechanism by which they develop are unknown. Potential systemic changes in the immune system may be linked to RPD pathophysiology. This talk will discuss how the phagocytic function of human peripheral blood monocytes and serum cytokine changes can be assessed. Immune system findings in participants with AMD both with and without reticular pseudodrusen compared to healthy controls will be discussed, along with the role of systemic immune factors in RPD pathogenesis.

Harmonizing big data and building research networks for AI applications: A global perspective
June 11 | 9 - 10:30pm EDT
Organizers: Sally L. Baxter, MD, MSc, University of California San Diego; Michelle Hribar, MS, PhD, National Eye Institute, Oregon Health & Science University; Kerry E. Goetz, MS, National Eye Institute
Advancements in computational tools and data have provided researchers with increasing ability to discover patterns, improve risk stratification, and predict patient outcomes. Data standardization is necessary for harmonization and analysis of data from different sources. The OMOP Common Data Model (CDM) is a widely used data model, including in the All of Us Research Program and the National COVID Collaborative (N3C), that standardizes and harmonizes data from multiple institutions. The OMOP CDM has supported both centralized data repositories and distributed research networks. These are crucial for big data analytics and AI applications. This SIG will convene an international group of experts to share their experiences developing or using data sources that leverage common data models. Speakers and moderators include experts from the All of Us Research Program, the European Health Data Evidence Network, the NIH Bridge2AI Consortium, the National Eye Institute, and the OMOP Workgroup in Eye Care & Vision research. Attendees will learn about recent advances and ongoing initiatives, and they will have an opportunity to engage in active discussion to help inform future efforts.

C. Ross Ethier, PhD, FARVO, Georgia Institute of Technology & Emory University
Aqueous humor outflow resistance is generated and homeostatically regulated by multiple, complex signaling processes. This presentation will give an overview of mathematical and computational models that relate the microarchitecture of the outflow pathway to its ability to generate flow resistance, and important signaling loops that maintain this resistance.
Secondary glaucoma: Bridging metabolomics to develop potential disease-specific therapies
June 20 | 9 - 10:30am EDT
Organizers: K'Mani Khimoii Blyden, BS, Medical College of Georgia, Augusta University, Augusta, GA, United States; Omar Badla, MBBS, Bascom Palmer Eye Institute, University of Miami, Miami, FL, United States
During this session, we aim to explore the role of metabolomics in developing disease-specific interventions for common causes of secondary glaucoma, such as pseudoexfoliative (PEXG) and pigmentary glaucoma (PG). Currently, there are no disease-specific interventions available for the treatment of either disease, resulting in a significant overlap in the treatment of these conditions and primary open-angle glaucoma/Glaucoma. Recent advances in metabolomic and molecular research have highlighted various pathways and molecules that play crucial roles in the pathophysiology of these diseases. These findings could serve as potential targets to create treatments that are specific to PEXG and PG. Our aim is to foster discussions among experts from various fields of ophthalmology to share insights and enhance our understanding. Through these collaborative efforts, we hope to encourage a multidisciplinary approach to better develop strategies addressing this issue.

Beyond the eye: Insights into Cerebral/Cortical Visual Impairment (CVI)
June 20 | 6 - 7:30pm EDT
Organizers: Kerry E. Goetz, MS, National Eye Institute; Erika Nelson, BS, National Eye Institute
CVI is a leading cause of pediatric visual impairment in the United States. Despite the disease burden, children with CVI are often misdiagnosed or their condition is not recognized until later in life due to a gap in clinician awareness and a lack of consensus definition. A working definition developed at a Trans-NIH Workshop in November 2023 defines CVI as a spectrum of visual impairment caused by an underlying structural and/or functional brain abnormality, which impacts development of visual function and processing. The visual dysfunction in CVI is greater than expected by any co-morbid ocular conditions. The visual abnormalities in CVI may manifest as lower- or higher-order afferent visual deficits, with or without efferent (oculomotor) disturbances, which adversely affect functional vision. While CVI may be co-morbid with other neurodevelopmental disorders, CVI is not primarily a disorder of language, learning, or social communication. Although the neurologic insult resulting in CVI occurs in the developing brain, individuals with a diagnosis of CVI may require long-term support extending into adulthood. In this SIG, expert panelists will share proposed definitions of CVI and research opportunities. Attendees will benefit by understanding ongoing initiatives and will have an opportunity to engage with experts in active discussion to help inform and be involved in future efforts.
Panelists

Ocular toxicity due to immunotherapies
June 20 | 6 - 7:30pm EDT
Organizers: Meghan Berkenstock, MD, Wilmer Eye Institute; Jasmine H. Francis, MD, Memorial Sloan Kettering Cancer Center; Lauren A. Dalvin, MD, Mayo Clinic
Treatment of systemic malignancies has evolved in the last 12 years with the FDA approval of immunotherapies. As new receptors and molecular targets within pathways are identified, new agents are developed and studied in clinical trials. Unfortunately, the same ligands targeted by the immunotherapy agents may also be located in the eye or adnexa. Similarly, off-target delivery of cytotoxic payloads may negatively impact ocular structures. Several meetings would occur, where each focused on one drug class per session. This SIG will also provide a forum to allow ARVO members to ask questions to ophthalmologists specializing in ocular toxicity management about the basic science behind or treatment of adverse events associated with these medications. Finally, this SIG would serve as a platform for discussion on how to create a resource for practitioners on ocular toxicities. Special attention would be paid to developing a system that is accessible and comprehensive , remains current and up to date and, legally complaint. Likewise, a dialog on developing systems for seamless communication between ophthalmologists and medical oncology care teams would be included in each meeting.

OCT biomarkers of intraocular inflammation
June 25 | 9 - 10:30am EDT
Organizer: Edmund Tsui, MD, MS, UCLA Stein Eye Institute
Uveitis is a vision threatening disease where accurate evaluation and treatment of inflammation is crucial to prevent the development of ocular complications and vision loss. Optical coherence tomography (OCT) of the anterior and posterior segment have recently been used in research settings to objectively quantify intraocular inflammation, such as anterior chamber cell, vitreous cell, vitreous haze, and structural biomarkers. Current research has sought to quantify the number of hyperreflective foci, which represent cells in the aqueous or vitreous, as well as the signal intensity, which has correlated with vitreous haze. Evaluation of the retinal and choroidal vasculature with OCT has also provided additional insight into disease monitoring. However, more research surrounding standardization of image acquisition and image analysis, still needs to be performed. Our SIG seeks to review the current landscape of OCT biomarkers of intraocular inflammation and discuss strategies in image acquisition and processing and formulate studies for further collaboration. This SIG will be an interactive discussion that also seek to discuss ideas and challenges in implementation of OCT as an objective measure of intraocular inflammation.

Get outer here: Should we consider the inner retina in AMD?
June 25 | 6 - 7:30pm EDT
Organizer: Lisa Nivison-Smith, B.Sc (Hons), PhD, School of Optometry and Vision Science, University of New South Wales, SYDNEY
Advances in retinal imaging have resulted in a wealth of evidence showing that the inner retina undergoes anatomical and physiological changes alongside the outer retina in age-related macular degeneration (AMD). However, there is a critical gap in understanding how this knowledge translates to improving outcomes for patients with AMD. Considering that the retina functions as a sum of its parts, measuring the compromise of the inner retina may be essential to determine the full extent of AMD pathophysiology and optimizing AMD diagnostics and interventions. This session will discuss: • What inner retina changes exist in AMD? • What are the origins of inner retinal changes in AMD? • What are the considerations of inner retinal changes in clinical assessment? Attendees will be encouraged to exchange ideas on how we can best harness current understanding of retinal imaging, biomarkers, and anatomy, to develop ideas for clinical translation of inner retinal assessments in AMD as well as furthering our understanding of the pathophysiology of AMD.
Presentations
- Inner retinal changes in the early stages of AMD
Matt Trinh, PhD, School of Optometry and Vision Science, University of New South Wales, SYDNEY
This presentation will provide an overview of the neuronal and vascular changes which have been recently observed in the inner retina in the early stages of AMD using a range of clinical retinal imaging techniques. The diagnostic and prognostic applications of these changes will also be discussed. - Central retinal artery and retinal VD/FAZ in AMD

Photoreceptor loss as an endpoint in clinical trials
June 25 | 9 - 10:30pm EDT
Organizers: Jayashree Sahni, MD, PhD, FRCOphth, Novartis Pharma AG & University of Liverpool; Nadia K. Waheed, MD, MPH, Tufts University School of Medicine, New England Eye Center @ Tufts Medical Center
With the identification of novel targets, the number of interventional clinical trials in ophthalmology has increased. The measurement of photoreceptor (PR) integrity using artificial intelligence/machine learning (AI/ML) algorithms on OCT is gaining traction in geographic atrophy, with reports suggesting better prediction of disease progression and potential to show greater benefit of novel therapies. However several steps including (a) standardization of image acquisition protocols (b) definition & terminology of PR alteration (normal vs attenuated vs loss) (c) AI algorithms developed using these definitions (d) well-powered natural history studies data on what PR change is clinically significant (e) validation and regulatory approval of algorithms, including suitability and performance of the algorithm when confounded by other retinal structural changes (f) conclusive structure/function correlation are needed. This SIG will bring together a panel of experts from industry and academia to a) Illustrate the potential for the broad application of PR loss as an endpoint for multiple retinal diseases. b) Discuss similarities and differences in parameters used to define PR loss in AI algorithms from recent literature and need for harmonization c) Discuss path forward with academic, industry and health authority collaboration to address gaps in order to leverage this novel endpoint for clinical trial and the real world

Intraocular pressure-independent models of glaucoma
July 11| 9 - 10:30am EDT
Organizers: Kevin C. Chan, PhD, FARVO, New York University Grossman School of Medicine; Henry Tseng, MD, PhD, Duke Eye Center
Glaucoma patients often continue to lose vision despite successful treatment with current intraocular pressure (IOP) lowering therapies, partly because IOP is only a major clinical risk factor for glaucoma, and a majority of primary open-angle glaucoma (POAG) patients have low or normal intraocular pressure. There is no neuroprotective therapy that minimizes retinal ganglion cell (RGC) loss in glaucoma, as the mechanism of RGC degeneration remains largely unclear. A major challenge in glaucoma research is the limited experimental model systems to study RGC degeneration independent of IOP. Unveiling the processes underlying age-dependent, progressive, and non-IOP-dependent features of RGC neurodegeneration in glaucoma will be crucial for basic and clinical applications. In this SIG, speakers will discuss exciting progress made in studying non-IOP-dependent RGC loss. We will discuss the challenges and opportunities of how novel retinoid, rodent, and non-human primate models can help uncover neurodegenerative mechanisms in glaucoma and identify potential drug compounds for pre-clinical pharmaceutical trials.
Presentations
- Retinoids and iPSC-based glaucoma model systems
Jason S. Meyer, PhD, Department of Medical and Molecular Genetics, Indiana University School of Medicine
One way to study glaucomatous neurodegeneration independent of intraocular pressure (IOP) is to utilize human retinal ganglion cells (RGC) derived from induced pluripotent stem cells. These cells can be studied in culture and induced to form a retinoid which allows multiple layers of the retina and RGC connections to be modeled. This talk will discuss current approaches and new developments. - Rodent models of normal tension glaucoma
Richard T. Libby, PhD, FARVO, University of Rochester School of Medicine
This talk with give an overview of recent developments in rodent glaucoma models that do not involve inducing elevated intraocular pressure. - Non-human primate models of glaucoma
Anita Chan, MBBS, MMed, FRCS, FRCPath, Singapore National Eye Center, Singapore Eye Research Institute
While few non-human primate (NHP) models of glaucoma exist, this talk will address the challenges involved in creating an NHP model of glaucoma independent of IOP.

Bioactive lipids in corneal and ocular surface disease
July 11 | 6 - 7:30pm EDT
Organizers: Nawajes Mandal, PhD, University of Tennessee Health Science Center, Memphis, TN, USA; Shizuya Saika, MD, PhD Department of Ophthalmology, Wakayama Medical University School of Medicine, Japan.
Lipids are essential components of every cell, but lipids as signaling molecules (bioactive lipids) for cellular physiology and metabolism is a recent discovery. Consequently, lipid metabolism and signaling are increasingly associated with many human diseases. Lipid signaling and lipid pathways are therefore being actively investigated to determine their role in the pathophysiology of the disease, find novel targets for therapeutic development, and be recognized as disease biomarkers. Bioactive lipids in corneal and ocular surface diseases are underexplored areas. Bringing together a group of clinical experts and ocular lipid biologists, this SIG will discuss the current standings of our understanding of lipid signaling in the cornea and ocular surface diseases and identify the gaps where future research should focus.

July 11 | 6 - 7:30pm EDT
Organizers: Rajat N. Agrawal, MD, MS, Retina Global; Charles DeBoer, MD, PhD, Byers Eye Institute at Stanford
Anti-VEGF injections are the current standard of care for management of retinal diseases and help preserve vision in a significant number of patients. But a substantial number of patients do not tend to do well with these injections. Also, the treatment burden associated with receiving multiple intravitreal injections over time leads to lack of compliance in a number of patients, affecting outcomes. There is a a strong push for developing a drug with a different mechanism of action and a different formulation to address the unmet need. Oral medications are currently in development for retinal diseases, which bring a unique set of challenges and perspectives. Being oral, they affect both eyes equally, while as systemic drugs, they may affect other systems in the body. This SIG will cover all relevant aspects of the process for getting these new types of drugs in retina to the patient, including clinical development, regulatory pathway and post-approval process, along with input from companies as well as perspectives on venture fund support for these initiatives.

Methodological considerations for real world data studies in ophthalmology
July 11 | 9 - 10:30pm EDT
Organizer: Durga S. Borkar, MD, MMCi, Duke University Eye Center
Real world data (RWD) are any data collected in routine clinical practice, including administrative claims, electronic medical record (EMR), imaging analyses, and patient-reported outcomes. Leveraged appropriately, RWD in ophthalmology can generate meaningful real world evidence to describe patient outcomes and inform care delivery. There are numerous methodological considerations in leveraging RWD that differ from clinical trials. Maximizing the potential of RWD in ophthalmology requires a deep understanding of data collection methods, data standards and interoperability, and the inherent strengths and limitations of each data source. This SIG will convene a panel of experts from across a variety of backgrounds to discuss methodological considerations in RWD uses in ophthalmology research, from visual acuity data derived from EMRs, approaches for capturing and interpreting output from optical coherence tomography imaging, and leveraging RWD for economic analyses. The panel will discuss important methodological considerations required to appropriately leverage each of RWD sources in the most meaningful way and engage in a conversation with the broader audience on the biggest areas for development in real world evidence generation and research.

Glaucoma, a leading cause of global irreversible blindness, is characterized by the progressive loss of retinal ganglion cells (RGCs) and optic nerve (ON) atrophy. While current treatments aim at reducing intraocular pressure (IOP), RGC loss and ON axon degeneration may occur independently of normal IOP. Consequently, recent progress has been made in developing potential new drug targets and neuroprotective therapies to restore visual function. Prolonged use of glucocorticoids (GCs) can lead to iatrogenic secondary ocular hypertension (OHT) and GC-induced glaucoma (GIG), mimicking primary open-angle glaucoma (POAG) clinically and pathologically. In light of this, the present session explores the role of corticoids and their receptors in glaucomatous eyes, emphasizing the molecular mechanisms behind GC-induced OHT, GIG, and POAG. Additionally, the discussion addresses potential new drug targets in glaucoma, focusing on neuroprotective strategies and corticoid receptor manipulation. Attendees are invited to contribute by sharing research findings, clinical experiences, and insights. Proposing new research questions and innovative treatment opportunities for glaucoma is also encouraged.

Advancements in defining and understanding the human ocular surface microbiome
July 23 | Noon - 1:30pm EDT
Organizers: Anat Galor, MD, MPH, University of Miami/Miami VA Medical Center; Anthony St. Leger, PhD, University of Pittsburgh School of Medicine
Recently, a great amount of effort, both financial and personnel-related, has been devoted towards defining and understanding the human ocular surface microbiome. The National Eye Institute has selected five teams to participate in a funded consortium to develop and optimize protocols towards collecting and analyzing the microbiome signatures from healthy human subjects. In addition to this, the consortium aims to establish causal relationships between specific microbes and physiological responses from host epithelial and immune cells. The purpose of this SiG is to present data from the consortium to include the definition of the microbiome signature using genomic approaches, isolating, and identifying live bacteria using culturomics, and establishing causal relationships using cell culture and in vivo animal models.

Evaluating biomarkers of Angiopoietin-2 inhibition in retinal vascular diseases
July 23 | 9 - 10:30pm EDT
Organizer: SriniVas R. Sadda, MD, FARVO, Doheny Eye Institute/ University of California - Los Angeles
Anti-VEGF therapies have improved outcomes in diabetic macular edema (DME), neovascular age-related macular degeneration (nAMD), and retinal vein occlusion (RVO), however they do not address the multifactorial nature of the diseases. In the phase 3 YOSEMITE/RHINE (DME) and TENAYA/LUCERNE (nAMD) studies, dual inhibition of Ang-2/VEGF-A with faricimab demonstrated improved anatomical outcomes with extended durability vs aflibercept Q8W. Determining the additional benefits of Ang-2 inhibition on disease biomarkers is an opportunity to explore how the biology may translate into improved clinical outcomes for patients. To assess the impact of dual Ang-2/VEGF-A inhibition on biomarkers in retinal vascular diseases, a panel of experts will discuss the scientific knowledge in the field of vascular biology as well as clinical findings from the phase 3 trials of faricimab on emerging Ang-2 biomarkers and their correlation with clinical outcomes.
