Frontiers in membrane dynamics and cellular communication: impact on vision and disease mechanisms – BI
Contributing sections: AP, GEN, GL, IM, PH, RE, RC, and VN
Organizers: Astra Dinculescu, Luminita I. Paraoan, and Elfride De Baere
Speakers: Vadim Y. Arshavsky, Yoshikazu Imanishi, Kapil Bharti, Kirill A. Martemyanov, Luminita I. Paraoan, and Abbot F. Clark
The plasma membrane is a dynamic structure that plays essential roles in maintaining cellular architecture and homeostasis. This Minisymposium will cover recent advances in plasma membrane biology by focusing on specific structural elements and interactions that enable cellular communication. Through specific structures and molecular components, such as the cilium, the synapse, transmembrane receptors, adhesion proteins, and points of contact between the plasma membrane and intracellular organelles, the plasma membrane integrates extra- and intracellular signals within complex functional pathways. This information will be put in the context of diverse ocular disorders, ranging from retinal degenerations and congenital night blindness to glaucoma and uveal melanoma. Understanding the fundamental processes that contribute to cellular communication pathways and context-related signaling provides a solid basis for uncovering therapeutic interventions for a wide range of ocular diseases.
Aging with Vision Loss: Understanding the aging consequences of visual impairment – CL
Contributing sections: LV
Organizer: Bonnielin Swenor
Speakers: Heather Whitson, David Lee, Ellen Freeman, Ecosse Lamoureux, and Alan Morse
A Visual impairment largely affects older adults, and as the global population ages, the prevalence of visual impairment is expected to rise dramatically. Research has documented that the impact of visual impairment goes beyond vision, as older adults with visual impairment have worse physical and cognitive functioning and are a greater risk of negative health outcomes such as disability and mortality. This session is focused on considering the impact visual impairment within the complexities of aging and will outline gaps in our understanding of the long-term health consequences of visual impairment older adults.

Retinal hemorrhage is an important sign of abusive head trauma in infants, but much is unknown about the underlying biomechanical mechanisms and forces. Such knowledge is critical to accurately diagnosing child abuse. This mini-symposium will begin with a review of the clinical context and multidisciplinary biomechanical research approaches, then define fundamental questions in the field, review some of the work already done, identify key gaps in our understanding, and work in collaboration with the audience to map research priorities going forward.
Healthcare transformation with AI: impact in glaucoma and ophthalmology – GL
Contributing sections: BI, CL, RE, and VI
Organizers: M. Francesca Cordeiro, Ross Ethier, and Michael Girard
Speakers: Alexander Thiery, Gustav de Moraes, Anil A. Bharath, Aaron Lee, and Carlos Ciller
Artificial Intelligence (AI) is a field that has recently seen unprecedented growth with applications across all fields of medicine including ophthalmology. In ophthalmology, AI has strong potential to significantly improve disease screening, diagnosis, prognosis, and eventually lead the way to personalized treatment. AI may also help us re-define pathologies. While AI is not yet used in the ophthalmology clinic, within the next 10-20 years, it is extremely likely that clinicians and ophthalmic surgeons will need to rely on or interact with AI software/technologies in their day-to-day clinical routine. This Minisymposium aims to understand how AI will change the clinical landscape in Ophthalmology, particularly focusing on glaucoma as an example, as this is an important example of a chronic, aging disease with a significant health-economic burden. It will discuss current and future research and industry trends that are likely to make an impact in the clinic. It will also discuss the strong limitations inherent to AI. This symposium aims to gather clinicians and scientists with interest in AI, engineers and computer scientists that are developing the next generation of AI algorithms, and industry members and policymakers who will play a critical role in the introduction of AI to the ophthalmology clinic.

Precision through measurement: biomarkers in health and disease – IM
Contributing sections: AP, RE, and VN
Organizers: Richard Lee and Jonas Kuiper
Speakers: Sarah Coupland, Darragh Duffy, Pearse Keane, and Russell Foster
Biomarkers are transforming medicine. In their various forms, they guide precision diagnosis and treatment and can be used to delineate health from the disease at both an individual and population level. Their discovery is not predicated by an understanding of the biological mechanism, but they nonetheless inform a deeper understanding of pathology. Most importantly, biomarkers help us to ensure the right patient gets the right treatment at the right time. In this symposium, we explore how characteristic mutations have recently been shown to define ocular malignancy and look outside the eye to consider the potential for heterogeneity in the human immune response to determine disease susceptibility and outcomes in a diversity of conditions. At a population level, algorithms have now been developed to shape healthcare delivery for common retinal diagnoses based on the automated analysis of images generated using widely available technologies, and this promises to change the landscape of global ophthalmic practice. The goal of the session is to touch on these broad-ranging subjects and give an overview of biomarker development in the context of the eye, concluding with a description of how light changes clock gene expression in our circadian pacemaker, and the impact this has on the ultimate biomarker of health (sleep).

Of mice and men: Comparing primate and rodent retina – VN
Contributing Sections: AP, RE, and RC
Organizers: Jan Kremers, Ulrike Grunert, and Erika Eggers
Speakers: Ulrike Grunert, Yi-Rong Peng, Greg Field, Machelle Pardue, Jan Kremers, and Jens Duebel
The visual system of humans and non-human primates is unique in several aspects. However, due to accessibility and the availability of molecular tools, mice and other rodents are often the models of choice to study the retina, the results of which are then extrapolated to the human situation. When taking results from bench to bedside and back again, it is extremely important to be able to understand the similarities and the differences between the retinae of rodents and primates. This minisymposium compares recent data on rodent and primate retinae at several levels (genetics, cellular properties, physiology, circuitry, etc.).
