Study Endpoints

Primary Endpoints

Change in Central Subfield Thickness in Study Eye
12 weeks

Change from baseline in Central Subfield Thickness (CST), as measured by Spectral Domain Ocular Coherence Tomography (SD-OCT), compared to placebo. Refer to Study Eye Inclusion/Exclusion Criteria for Study Eye definition. Only one eye was chosen as the Study Eye. In the event both eyes were eligible, the eye with the worse edema (greater CST value) was considered for the purpose of this study as the Study Eye. If both eyes had the same level of edema, the right eye was selected.

Secondary Endpoints

Change in Best Corrected Visual Acuity in Study Eye
12 weeks
Gain of ≥5 Letters in Best Corrected Visual Acuity in Study Eye
12 weeks
Loss of ≥5 Letters in Best Corrected Visual Acuity in Study Eye
