Diabetic retinopathy damages the blood vessels in the retina and is the leading cause of vision loss in working-age adults. About one-third of people with diabetes develop some form of retinopathy. Current treatment includes laser therapy, anti-VEGF injections into the eye, and careful blood sugar control to slow progression.

What's actually going on in research

Trials are testing longer-acting anti-VEGF drugs to reduce injection frequency, combination therapies that address inflammation alongside leaky vessels, gene therapy approaches, and drugs delivered as eye implants. Research also focuses on identifying people at highest risk through AI analysis of retinal images and on early interventions before vision loss begins.

Longer-acting anti-VEGF drugs

New formulations aim to extend the time between eye injections from every month or two to three or four months. Several drugs in late-stage trials use different approaches to sustain drug levels in the eye.

Gene therapy

Trials are testing one-time gene therapy that would enable the eye to produce its own anti-VEGF protein. If successful, this could replace the need for repeated injections over years.

Sustained-release implants

Small drug-releasing devices placed in the eye aim to deliver medication continuously for months at a time. These could reduce the treatment burden for people requiring frequent anti-VEGF injections.

What to know before you search

Eligibility typically depends on retinopathy severity, whether the center of the retina is affected, visual acuity level, and previous treatments received.

What types of trials are currently open

  • Anti-VEGF trialsTesting new drugs that block vascular endothelial growth factor, which drives abnormal blood vessel growth in the retina. These trials often compare injection frequency and vision outcomes.
  • Combination therapy trialsTesting anti-VEGF drugs combined with steroids or other drugs that target inflammation and fluid buildup.
  • Gene therapy trialsTesting one-time treatments that introduce genetic instructions for the eye to produce anti-VEGF protein on its own.
  • Prevention trialsTesting whether early treatment in people with mild retinopathy can prevent progression to vision-threatening disease.
  • Device and delivery trialsTesting implants, port systems, and new injection techniques to deliver drugs more effectively or reduce treatment burden.
