简要总结
This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

结局指标
主要结局
Mean Average BCVA Change From Month 1 Through Month 6 to Baseline
时间窗: Baseline, month 6
the average of the changes in BCVA (letters) from baseline to any post-baseline visit, i.e. the mean of six differences to baseline for the six post-baseline visits at month 1 to 6. BCVA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. An ETDRS visual acuity score of 85 is pproximately 20/20. An increased score indicates improvement in acuity
次要结局
- Change Over Time in BCVA(Baseline, month 6)
- Time to Achieve a Significant Improvement ≥ 15 Letters(Baseline, month 6)
- Number of Patients Gaining / Losing ≥ 15 / 10 / 5 Letters(Baseline, 6 month)
- Change Over Time of the Central Retinal Thickness (CRT)(Baseline, month 6)
- Changes in the Quality of Life According to the National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) Questionnaires(Baseline, month 6)
- Changes in the Quality of Life According to the Short Form (36) Health Survey (SF-36)Questionnaires(Baseline, month 6)
- Changes in the Quality of Life According to Euro Quality of Life (EQ-5D) Questionnaires(Baseline, month 6)
- Increase Rate of the Internal Ocular Pressure (IOP ) : Patients With ≥10% Increase in IOP Compared to Baseline(Baseline, month 6)
- Mean BCVA Change at Month 6(Baseline, month 6)
