Measure Description |
Time Frame |
|---|---|---|
|
Mean Increase From Baseline in ETDRS Letters Read at 26 Weeks and Off-drug Follow-up Visit
Time Frame: 26/39 weeks
|
Best Corrected Visual Acuity (BCVA) was assessed at all the visits, with refraction as necessary.
VA measurements were taken in a sitting position at a test distance of 4 meters using early treatment diabetic retinopathy study (ETDRS) charts.

Changes in Visual Field Observed Following the Treatment
Time Frame: 26 weeks
|
Visual field mean deviation (MD) changes from the screening at week 26 using with the HVF 24-2 FASTPAC program using the size III or Size V test stimulus
|
26 weeks

|
Changes Mean RNFL Thickness in NAION Eyes Change From Screening to Week 26
Time Frame: 26 weeks
|
TMean RNFL thickness measured by OCT.
The data are in microns, as measured with an Opko OCT machine.
