Neovascular AMD: Bevacizumab Injection Increases Angiogenic Biomarkers

Dr. Thiago Cabral

Neovascular age-related macular degeneration (nAMD) is induced by the development of new abnormal ‘leaky’ blood vessels in the choroid and retina, when the balance of pro- and anti-angiogenic factors is upset. Vascular endothelial growth factor (VEGF) is considered a critical modulator of angiogenesis and is related to induction of endothelial cell migration and proliferation after hypoxia. The development of anti-VEGF agents, such as bevacizumab (Avastin®), ranibizumab (Lucentis®) and aflibercept (Eylea®), revolutionized the treatment of nAMD.

A novel drug for treatment of diabetic retinopathy

Scientists at the Centenary Institute have developed a novel drug which could potentially be used to effectively treat patients with diabetic retinopathy.

Diabetic retinopathy often occurs in diabetic patients, even when their blood sugar levels are controlled. In diabetic retinopathy, the tiny blood vessels in the retina are damaged and can leak fluid or haemorrhage, often leading to vision loss.

A Biomarker could predict response of intravitreal injections in Diabetic Macular Edema

Researchers at St. Michael’s Hospital have found an association with a biomarker from aqueous fluid in the eye that predicts which patients will respond best to current treatments for diabetic macular edema. Their findings suggest this biomarker may be not only a marker of disease severity and anatomic response but also a potential therapeutic target in DME, recognizing that in patients with DME, there is not always a direct correlation between anatomic and visual acuity response.
