A single procedure may be as effective as repeated anti-VEGF injections claims Timothy L. Jackson.

Blindness in millions of people with diseases that starve eye tissue and nerves of oxygen might be averted with a procedure being developed by researchers at Oak Ridge National Laboratory, the University of Southern California and the University of Tennessee.

According to Eye Research Australia researchers at the University of Melbourne, a high intake of fresh and processed red meat is positively associated with early AMD, the leading cause of blindness among older people. Diet has often been postulated to alter the risk of AMD.

The CABERNET (CNV Secondary to AMD Treated with Beta RadiatioN Epiretinal Therapy) clinical trial is pivotal to establishing the safety and effectiveness of a beta radiation based focal epimacular brachytherapy device. Its development in bringing a paradigm shift in the way retina specialists treat wet AMD patients moved a step closer as Neovista Inc. secured more than $18 million in its Series D private venture funding round.

The Iluvien fluocinolone acetonide intravitreal insert (Alimera Sciences, Inc) is safe and effective in the management of diabetic macular oedema (DME) at twelve months, according to study results released by Alimera.

Scientists studying a neural retina in a salamander have found Müller cells in the promoted cone-specific pigment regeneration and dark adaptation that are independent of the pigment epithelium.

Laser burn to the retina of a single eye can compromise the immune privilege of the fellow eye.
