Patients with diabetic macular oedema (DME) who received aflibercept injection demonstrated a significantly greater improvement in mean change in best-corrected visual acuity (BCVA) from baseline at 52 weeks compared to those who received either bevacizumab or ranibizumab.

There is a correlation between functional cell loss in the retina and signs of dementia in people who have a genetic risk for frontotemporal dementia (FTD), according to researchers from the US.

The US Food and Drug Administration (FDA) has approved a low-dose corticosteroid intravitreal implant for the treatment of diabetic macular oedema. (DME).

Monthly monitoring is no longer required for patients taking ranibizumab (Lucentis, Novartis) for a condition that is stable, due to a change in the drug's licence.

Non-damaging photothermal therapy using a pattern-scanning laser (PASCAL) guided by proprietary software is a safe and effective treatment for chronic central serous retinopathy (CSR), according to a recent study.

Long-term observational data presented at the 2014 European Society of Retina Specialists (EURETINA) conference support the safety and efficacy profile of the anti-vascular endothelial growth factor (anti-VEGF) agent ranibizumab (Lucentis, Novartis) for the treatment of appropriate patients across its indications

The European Commission has extended marketing authorization for an intravitreal implant with 700 mcg of dexamethasone in an applicator (Ozurdex, Allergan) for the treatment of adults with visual impairment caused by diabetic macular oedema (DME) who have pseudophakia or whose condition is considered insufficiently responsive to or unsuitable for non-corticosteroid therapy.

In a recent satellite symposium, sponsored by Bayer, the topic of macular oedema following CRVO was discussed by a panel of experts. Here, we present a summary of this meeting, highlighting the key outcomes.

KalVista Pharmaceuticals has begun a Phase I trial of its plasma kallikrein inhibitor KVD001 for the treatment of diabetic macular oedema (DME).

Researchers examining age-related changes in heparan sulphate (HS) quantity and composition in human Bruch's membrane (BrM) have discovered that the quantity greatly decreases with age, resulting in fewer binding sites for complement factor H (CFH) and affecting the ability of the 402H variant of CFH to bind BrM.

Aflibercept is effective in inhibiting vascular endothelial growth factor (VEGF) for a prolonged period of time, but possible side effects draw concerns about its long-term use in patients with age-related macular degeneration, diabetic macular oedema and retinal vein occlusion, according to the conclusions of a new study.

Inhibiting thrombin activity may be a treatment option for proliferative vitreoretinopathy (PVR), given that such activity is increased in the vitreous of patients with the disease and is associated with the activation of pro-inflammatory and pro-fibrotic pathways in retinal pigment epithelium (RPE) cells.

Vasodilators and oral beta-blockers are associated with an increase in the hazard of incidence of early age-related macular degeneration (AMD) and exudative AMD, respectively, according to research recently published online.

The systemic pharmacokinetics and pharmacodynamics of three anti-vascular endothelial growth factor (VEGF) treatments after they are administered intravitreally differ in ways that "may provide biological plausibility for potential differences in systemic safety risk," according to recently published research.

In 2010, 2.1 million people were blind and 6 million people were visually impaired because of macular diseases other than diabetic maculopathy, according to a meta-analysis conducted by members of the Vision Loss Expert Group of the Global Burden of Disease Study Group.

To address issues around ourcomes, dosing and safety of anti-VEGFs, an independent scientific symposium (sponsored by Novartis) was held during COPHy. Here, we present some brief highlights of this meeting.

The AREDS 1 and 2 studies provide important information about the role of ocular nutrition in macular degeneration. However, to benefit patients, the findings must be condensed into clear and concise advice that will help them select appropriate vitamin supplements and follow a healthy lifestyle.
