Bevacizumabe or Triamcinolone for Persistent Diabetic Macular Edema

Summary

Background: Diabetic macular edema (DME) shows a sustained functional and morphologic response to anti-vascular endothelial growth factor (VEGF) drugs, but the optimal approach for persistent macular edema still in debate. Purpose: To evaluate 24-week visual and anatomical effects of intravitreal bevacizumabe or triamcinolone in patients who have residual edema after 24-weeks to "pro re nata"(prn) intravitreal bevacizumabe therapy. Methods: This study will enroll a total of 100 DME eyes. Each patient will receive "prn" bevacizumabe therapy throughout 24 weeks. At week 24, patients who have recurrent or persistent edema were randomized 1:1 to Group 1 (prn bevacizumane) or Group 2 (prn triamcinolone). Patients with no recurrent or persistent edema at week 24 will comprise to Group 3 and continue receive prn bevacizumabe. Prn treatment was administered when central subfield thickness of the macula (CST) \> 300 µm and/or there are intraretinal cystoid spaces in the fovea. Study visits will occur every 4 weeks with the endpoint at week 48. At each visit, patients will have an eye exam and CST, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were assessed. Fundus photography and fluorescein angiography will also perform at baseline, week 16, week 40, and week 48. All patients will resume standard care after exiting.
