Secondary Outcome Measures

Name	Time	Method
Best-corrected visual acuity	Change from Baseline at 8 weeks	Measurement of Best-corrected visual acuity (distance and near) using a logMAR chart.
The change of Endothelin-1 (ET-1)	Change from Baseline at 8 weeks	Fasting venous blood will be sampled to measure concentrations of ET-1.
