Macular Edema in Diabetes Medication
- Author: Emmanouil Mavrikakis, MD, PhD; Chief Editor: Hampton Roy Sr, MD more...
Medication Summary
As with all complications of diabetes, successful management of macular edema requires good control of the diabetes itself. A variety of intravitreal medications are currently available, with others under study. Medical treatment should focus on optimizing glycemic and hypertensive control and lowering lipid levels.
Corticosteroids
Class Summary
Corticosteroids such as triamcinolone have anti-inflammatory effects and can be used for the treatment of diabetic macular edema.
Triamcinolone acetonide (Triesence)
Triamcinolone is a synthetic corticosteroid with anti-inflammatory effects. It is indicated for several ophthalmic diseases such as ocular inflammatory conditions and visualization during vitrectomy. Intravitreal triamcinolone is also being used in the treatment of diabetic macular edema.
Anti-VEGF Agents
Class Summary
Vascular endothelial growth factor (VEGF) increases retinal vascular permeability, causes breakdown of the blood-retina barrier, and results in retina edema. VEGF is up-regulated in diabetic retinopathy. Three currently available anti-VEGF agents are pegaptanib sodium, ranibizumab, and bevacizumab.
Ranibizumab (Lucentis)
Ranibizumab is a recombinant humanized antibody fragment that is active against all isoforms of VEGF-A. Intravitreal ranibizumab is FDA approved for the treatment of exudative ARMD and retinal vein occlusion.
Bevacizumab (Avastin)
Bevacizumab is a full-length recombinant humanized antibody that is active against all isoforms of VEGF-A. It is FDA approved as an adjunctive systemic treatment for metastatic colorectal cancer.
Pegaptanib (Macugen)
Pegaptanib sodium is a pegylated aptamer directed against the VEGF-A165 isoform. It was the first FDA-approved ophthalmologic anti-VEGF agent for the treatment of choroidal neovascularization (CNV) from age-related macular degeneration (ARMD).
