STAMP: Steroid vs. Anti-vascular Endothelial Growth Factor for Diabetic Macular Edema Prior to Phacoemulsification
Study Details
Study Description
Brief Summary
The primary objective of this study is to compare the efficacy of antecedent intravitreal anti-vascular endothelial growth factor therapy vs. Ozurdex in reducing post-cataract surgery related macular edema in patients with pre-existing diabetic macular edema.

Phase 4 |
Detailed Description
In patients with pre-existing diabetic macular edema, anti-vascular endothelial growth factor therapy (Bevacizumab, ranibizumab, or aflibercept) will be compared to Ozurdex therapy administered 1 week prior to phacoemulsification cataract extraction. Spectral domain optical coherence tomography and visual acuity will be acquired at 1 week, 1 month, 2 months, and 3 months following cataract surgery.

Outcome Measures
Primary Outcome Measures
- Comparison of central foveal thickness outcomes of anti-vascular endothelial growth factor vs. Ozurdex therapy [3 months after cataract surgery]
Central foveal thickness will be measured in microns by spectral domain optical coherence tomography (Heidelberg) and compared to baseline at post-operative week 1, postoperative month 1, postoperative month 2, and postoperative month 3 for both anti-vascular endothelial growth factor and Ozurdex groups
Secondary Outcome Measures
- Visual acuity outcomes of anti-vascular endothelial growth factor vs. Ozurdex therapy [3 months after cataract surgery]
Snellen visual acuity will be measured and converted into logMAR and compared to baseline at post-operative week 1, postoperative month 1, postoperative month 2, and postoperative month 3 for both anti-vascular endothelial growth factor and Ozurdex groups
