Summary

The goal for this study is to initiate a randomized, controlled clinical trial to test the viability of personalized AMD progression prediction models. Early and intermediate AMD patients will be recruited and randomly assigned them to a control or test group. The test group will include patients who will receive personalized follow-up care based on their predicted risk, and collect baseline and follow-up data. This work will advance the AMD field by improving the identification of high-risk patients as candidates for more frequent screening and earlier treatment, leading to better clinical outcomes.

Detailed description

More than 90% of patients with advanced AMD have severe vision loss. Predicting AMD progression from an early or intermediate stage is crucial, since prompt intervention after a choroidal neovascularization (CNV) event and geographic atrophy (GA) monitoring can greatly improve visual outcomes. Patients at higher risk of progression should have more frequent follow-up visits, since progression often occurs before any visual changes are noticed by the patient. Previous work has determined the risk factors for AMD progression based on drusen features in fundus photos, Optical Coherence Tomography (OCT) and from genetic factors. However, current models are limited by their ability to make predictions over short intervals, which limits their utility in guiding screening intervals. In this study we will recruit patients with early and intermediate AMD in at least one eye who are at risk of converting to wet AMD or GA expansion. We will perform a randomized trial where we will randomly assign them to a control or test group (personalized follow-up care starting at 3 months based on their predicted risk from algorithm results), and collect baseline genetic, demographic, imaging, and clinical data and first follow-up data at the 3 month and 6 month follow-up time points. Outcomes will be measured to determine if an algorithm predicting early follow-up for high-risk patients (3 month) is advantageous over the standard 6 month follow-up time point.

Interventions

Type	Name	Description
OTHER	Algorithm prediction	Patients with early and intermediate AMD in at least one eye who are at risk of converting to wet AMD or GA expansion will be randomly assigned to a test group or control group. The test group will have their baseline data analyzed by an algorithm to predict the probability of conversion to wet AMD. If the probability is high for conversion at or before 3 months, patients will have earlier follow-up care than the control group (standard follow-up care every 6 months).
