Study used curated real-world data from the IRIS Registry to report risk of progression by stage

SAN FRANCISCO, Dec. 15, 2022 —Verana Health®—a digital health company elevating quality in real-world data—today announced that Ophthalmology and Therapy, an international, peer-reviewed medical journal, has published the results of a study Verana Health conducted to analyze American Academy of Ophthalmology (Academy) IRIS® Registry (Intelligent Research in Sight) data for insights into characterizing the most common form of vision loss in the elderly population, age-related macular degeneration (AMD). The study, “Dry Age-Related Macular Degeneration: Distribution of Visual Acuity and Progression Risk in a Large Registry,” is a novel study to report on how the stage of disease, as determined by visual acuity (VA), can help predict the risk of progression in dry AMD (dAMD) by stage.

Macular degeneration occurs when a person’s retina becomes damaged over time, leading to different levels of vision loss. There are two types of AMD: dry and wet. Dry AMD occurs in 85% to 90% of all AMD patients. The most advanced form of dAMD is called geographic atrophy (GA), a condition in which regions of the macula cease to function. There are no available treatments for GA, which impacts roughly 1.5 million Americans and can lead to irreversible vision loss and even blindness. 

The study used curated real-world data (RWD) from the Academy IRIS Registry—managed by Verana Health’s VeraQ population health data engine—to better understand how patients progress through the stages of dAMD. After searching a database of de-identified patient records, researchers evaluated a cohort of approximately 645,000 patients with confirmed dAMD. 

Tracking these patients over a four-year period (2016-2019), the study determined that patients with a lower ability to see, or lower VA, at the beginning of the study period had more advanced dAMD. Researchers also concluded that as these patients’ disease worsened, so did their vision. More specifically, the study concluded that:

“The clinical recommendation we can draw from this study is that if you have a patient with intermediate AMD, you need to watch them more closely than someone with mild dry AMD,” said Theodore Leng, M.D., director of research at the Byers Eye Institute at Stanford University School of Medicine and a Verana Health medical advisor. “These findings highlight the need for new medication options to reverse or delay the worsening of dry AMD and improve the quality of life for patients. We are hopeful that the results will guide novel therapies for dry AMD that are on the cusp of being approved.” 

The IRIS Registry is one of the largest specialty society clinical data registries in all of medicine, containing ophthalmic records for more than 75 million patients stretching approximately 10 years. Verana Health is the end-to-end data and technology partner for the IRIS Registry, responsible for data curation, electronic health record (EHR) integration, analytics, practice support, and quality reporting for physicians contributing to the registry.
