Summary

This trial investigates the effects of different treatments on patients with diabetic macular edema (DME) who have undergone vitrectomy surgery. The study found that anti-VEGF therapy, particularly ran

Who is the study for?
This trial is for patients with diabetic macular edema who have had a vitrectomy surgery. It's designed to see if high doses of Aflibercept can better improve their condition, considering the faster clearance of medication from eyes that have undergone this procedure.
What is being tested?
The study tests whether a higher dose (8 mg) of Aflibercept, an anti-VEGF therapy, can provide better outcomes for those with diabetic macular edema after vitrectomy surgery compared to standard treatments.
What are the potential side effects?
Aflibercept may cause eye-related side effects such as redness, irritation, or blurred vision. There might also be risks associated with intravitreal injections like eye infection or increased intraocular pressure.

Trial Design

1Treatment groups
Active Control
Group I: Patients with previous vitrectomy and diabetic macular edema treated with high dose afliberceptActive Control1 Intervention
Identify patients that have had a previous vitrectomy and have DME that requires anti-VEGF therapy. Then using a treat-extend-stop protocol6,7 that I previously published, treat patients with DME using high dose aflibercept, until the fluid has resolved and then extend the time interval in between treatments for those patients, while maintaining a fluid-free macula.
