Abstract

Purpose: To evaluate the changes in intraocular cytokine after intravitreal bevacizumab (IVB) for uveiticcystoid macular edema (CME). Methods: The authors evaluated 9 eyes of 8 patients who underwent IVB for uveitic CME. The aqueous humorlevels of vascular endothelial growth factor (VEGF), interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, and transforming growth factor (TGF)-β2were measured using suspension array technology at baseline and 1 month after IVB. Results: The VEGF level was decreased to insignificant level (p=.008). TGF-β2 and TNF-α levels increased significantly (p=.008 and .021, respectively). IL-6 and IL-8 showed no significant change (p=.051 and.110, respectively). Conclusion: IVB resulted in a significant decrease of VEGF levels, which was associated with anatomical improvement of CME at 1 month. Compensatory elevations of proinflammatory cytokines (IL-6 and IL-8) after selective VEGF inhibition were not observed. Marked elevation of TGF-β2 after IVB seems to play an immunosuppressive role.
