Top Cities for Diabetic Retinopathy Clinical Trials
Diabetic Retinopathy clinical trials are recruiting across 80 cities. Here are the cities with the most active studies:
Diabetic Retinopathy Trial Phases
27 research organizations are sponsoring diabetic retinopathy trials.
About Diabetic Retinopathy
Diabetic retinopathy is a diabetes complication that affects the blood vessels in the retina and is the leading cause of blindness in working-age adults. Diabetic macular edema (DME) involves fluid accumulation in the macula. Treatment includes anti-VEGF injections, laser therapy, and blood sugar control.
Clinical trials are advancing new treatments for diabetic retinopathy. Currently, 33 studies are recruiting a combined 11,186 participants across the United States. Research is being conducted by 27 organizations including University of Wisconsin, Madison, Johns Hopkins University, National Eye Institute (NEI) and 24 others.
2026 Diabetic Retinopathy Research Landscape
As of August 2026, the diabetic retinopathy clinical trial landscape includes 33 actively recruiting studies across 80 cities in the United States. These studies are collectively seeking 11,186 participants, with an average enrollment target of 339 per study.
The research spans multiple phases of development: 9 studies are in PHASE2, 6 studies are in NA, 6 studies are in PHASE3, 6 studies are in PHASE1, 1 study is in PHASE4. The presence of Phase 3 trials indicates that some diabetic retinopathy treatments are in late-stage testing and may be approaching regulatory review.
Research is being led by 27 different organizations, including University of Wisconsin, Madison, Johns Hopkins University, National Eye Institute (NEI), Ocular Therapeutix, Inc., iHealthScreen Inc, and 22 others. The large number of sponsors reflects significant research interest and investment in diabetic retinopathy treatment advancement.
Geographically, diabetic retinopathy trials are most concentrated in Glendale, California (4 trials); Phoenix, Arizona (4 trials); Beverly Hills, California (4 trials); Hagerstown, Maryland (3 trials); Pasadena, California (3 trials) and 7 other cities.

Video-based Patient Education Intervention for Diabetic Eye Screening in Latinx Communities
An online survey (n=1,500) and 4 focus groups will be conducted with Latinx patients with diabetes (n=20) to obtain preliminary data regarding whether and how patient and clinician video testimonial interventions (n=6) increase eye health literacy and trust in healthcare.
Optical Coherence Tomography Angiography in Subjects With Retinal Vascular Disease
This study will perform a prospective, longitudinal analysis of clinical and imaging findings from normal controls and subjects with retinal vascular disease to better define the diagnostic imaging criteria that signify change in disease stage. This includes disease progression in early stages of disease or disease regression with appropriate standard-of-care treatment.
Cell Collection to Study Eye Diseases
Background: \- Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, saliva, urine, and blood can be used for research. Researchers want...
