Development of Intravitreal Ranibizumab by Determining the Pathogenesis of Macular Edema With Retinal Vein Occlusion
Study on the Correlation Between the Treatment Effectiveness of Ranibizumab and the Role of the Cytokines in Macular Edema With Retinal Vein Occlusion
研究概览
详细说明
Methodology:
Aqueous humor samples (0.1ml) were obtained during intravitreous injection of ranibizumab to measure the levels of cytokines. Targeted cytokines are follows; IL-1, IL-2, IL-6, IL-8, IL-9, IL-10, IL-12, IL-13, IP-10, MCP-1, MMP-1, MIP-1β, PDGF, VEGF, PlGF, ICAM-1, TNF-α, RANTES, VEGFR-1, VEGFR-2, which has been reported that the expression level is increased in macular edema associated with RVO. Cytokines are measured by multiple ELISA (Luminex). Aqueous humor samples are obtained in the same manner from patients recurred after the first injection or continuous monthly injections. Statistical analysis is conducted to examine the difference of cytokine levels between early or late/incomplete responders of ranibizumab, and predict the number of injections to stabilize cytokine levels.
Number of centers & patients: Single center, 100 patients
Sample size justification: Sample size calculation was not done, since this study is a single-arm, observational study.
Population: Inclusion criteria: patients with RVO and macular edema
