Assessment
Primary outcomes
The reduction in the mean central retinal thickness evaluate on optical coherence tomography scan.
Key secondary outcomes
The mean best-corrected visual acuity changes over the follow-up and the proportion of eyes that gained at least 15 letters (approximately 3 lines) at the 12-month examination.
