Prediction of Progression of Age-Related Macular Degeneration

November 17, 2020 updated by: Joelle Hallak, University of Illinois at Chicago

A Novel Approach to Personalized Prediction of Progression of Age-Related Macular Degeneration

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.

Study Overview

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.

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Prediction Algorithm
Patients in the test arm will have a screening visit, then will come for two follow-up visits, at 3 months (if the algorithm determines high-risk of conversion within 3 months) and 6 months.
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).
No Intervention: Control
Patients in the control arm will have a screening visit, then will come for one follow-up visit, at 6 months (standard care) only.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Acuity
Time Frame: one year
The primary outcome measure will be the difference in visual acuity between test and control patients in those who progressed to late stage AMD
one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Actual risk of conversion
Time Frame: one year
The actual risk/ of conversion to wet AMD will be calculated for each eye that progressed using regression analysis. This risk will be compared to the risk that the algorithm predicted.
one year
Number of visits
Time Frame: one year
Number of visits will be compared between the test arm and the control arm of patients who progression to wet AMD
one year
