Trial Outcomes & Findings for Ranibizumab for Treatment of Persistent Diabetic Neovascularization Assessed by Wide-Field Imaging (NCT NCT00606138)

NCT ID: NCT00606138

Last Updated: 2023-04-10

Results Overview

This is a measurement of how much change in neovascularization has occurred, using the Optomap FA readings to calculate the increase or decrease in surface area of the retina that is affected by neovascularization.

Recruitment status

COMPLETED

Study phase

PHASE1/PHASE2

Target enrollment

9 participants

Primary outcome timeframe

Baseline to Week 4; Baseline to Month 4-6

Participant Flow

Subjects will be recruited starting in 2007 and until sufficient subject population is reached. They will be seen in an eye clinic at Rush University Medical Center.

There is no wash-out period. Recruited subjects must be in need of treatment for their PDR, and will be randomized and treated at the baseline visit. There were a total of 8 participants treated.
