- Primary Outcome Measures
Name Time Method o increase in macular thickness or fluid on optical coherence tomography.<br><br>No reduction of best corrected ETDRS visual acuity of more than 5 letters[Baseline and Week 24]
- Secondary Outcome Measures
Name Time Method Best corrected visual acuity will be tested by Early Treatment Diabetic Retinopathy Study (ETDRS) eye Charts. The patients will be asked to read letters from the top of the chart to the bottom, and the visual acuity is scored by how many letters could be correctly identified.[Baseline, Week 12, week 24, and Week 48];Central and inner macular thickness (from retinal pigment epithelium to inner limiting membrane) measured by optical coherence tomography[Baseline, Week 12, week 24, and Week 48];The leakage area of the fluorescein dye form retinal or choroidal vessels on fluorescein angiography[Baseline, week 24 and Week 48];Central visual field (Macular function ) is assessed by Flicker Frequency Perimetry (Medmont)[Baseline, week 24 and Week 48];Health-related quality of life assessed by National Eye Institute Visual Functioning Questionnaire-25[Baseline, Week 24 and Week 48]
