Outcome

Type
PRIMARY
Title
Proportion of Subjects Demonstrating ≥ 15 Letter Improvement From Baseline in Early Treatment of Diabetic Retinopathy Study (ETDRS)
Description
Best corrected visual acuity (BCVA) refers to the measurement of the best possible vision that can be achieved following refraction or correction. BCVA was assessed following the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol and was measured in the number of letters read correctly on an ETDRS eye chart. An increase from the pre-treatment state in BCVA of 15 letters or more represents a clinically meaningful improvement.
Time frame
2 months
Population
The Intent-to-treat population included all randomized subjects who received at least one study treatment.
