09:00am-12:00pmWorkshop A
Developing Preclinical Models That Recapitulate Disease Phenotypes of Retinal Pigment Epithelium & Photoreceptor Cells for Efficient Translation Into the Clinic
Synopsis
The lack of reliable preclinical models for dry AMD and geographic atrophy have proved to be a major hurdle in current AMD drug discovery and research. Several genetically modified mouse models previously developed have failed to fully recapitulate the AMD phenotypes, therefore, posing as a challenge during translation into the clinic.
Join this workshop to:
- Discuss the lack of accurate preclinical models replicating the retinal microenvironment including cell atrophy, loss of photoreceptor and RPE cells, deposition of drusen and the accumulation of lipofuscin, as seen in patients with dry AMD and GA
- Develop in vitro cell culture models (such as iPSC-derived RPE cell lines), organ-onchips and 3D organoids providing physiologically relevant models combining the various retinal cell types
- Overcome the lack of accurate in vivo models capturing different disease manifestations with the development of novel RPE-specific knockouts mouse models
- Uncover the latest advancements in tissue characterization techniques, including single-cell sequencing, spatial histology, proteomics, and RNA sequencing, and how these techniques provide insights into the origins of diseases by analyzing human tissues at a granular level
- Examine the challenges of comparing data across different models (oxidative stress vs genetically modified), emphasizing the importance of standardized methodologies to facilitate collaboration and data interpretation

Novel Non-Invasive Retinal Imaging Biomarkers to Precede Geographic Atrophy
Synopsis
Geographic atrophy includes photoreceptor depletion, reactive gliosis, and adhesion of retina to underlying tissue. Novel biomarkers are required for fast and accurate detection of disease stages earlier than atrophy. Current biomarkers for dry AMD include the presence and size of visible drusen deposits. However, drusen dynamism and the lack of methods for invisible drusen material limit their use as biomarkers. Recent histology defining the atrophy border in the neurosensory retina and validating OCT reflectivity make it possible to consider new methods, such as ellipsoid zone reflectivity, hypertransmission, and fundus autofluorescence.
Join this workshop to:
- Explore methods for imaging ellipsoid zone reflectivity and thickness, and understand their significance in evaluating retinal health
- Learn about emerging biomarkers, like hypertransmission defects that are valuable indicators of RPE dysfunction, identified through natural history studies, which serve as reliable precursors to geographic atrophy
- Learn about current biomarkers related to the retinal pigment epithelium health, emphasizing that the RPE can remain healthy up to intermediate stages of disease
- Utilizing OCT imaging and colour fundus photography to measure subretinal drusenoid deposits and hyporeflective
