New study suggests novel ways to treat serous retinal detachment

Wet age-related macular degeneration (AMD) is the leading cause of severe vision loss in older individuals. AMD and other serious chronic eye problems that affect younger individuals result when fluid accumulates abnormally under or within the retina. A new study published in The American Journal of Pathology shows for the first time that the release of substances from mast cells may be a causal factor in this type of eye pathology, and inhibitors of this release may offer new ways to treat serous retinal detachment.

Polypoidal choroidal vasculopathy shows distinct classification

Researchers have found that idiopathic polypoidal choroidal vasculopathy has significant clinical differences to neovascular age-related macular degeneration and suggest that it should be considered a distinct entity.

ORT incidence increases in nAMD despite anti-VEGF treatment

Swiss researchers report that patients with neovascular age-related macular degeneration (nAMD) experience increased incidence of outer retinal tubulation over time, despite treatment with a vascular endothelial growth factor blocker.

Johns Hopkins researchers develop new imaging technology to help remove brain tumors safely

Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact — and visually distinguishing the two is often impossible.

UC Davis' John S. Werner wins 2015 Verriest Medal from International Colour Vision Society

John S. Werner, a UC Davis neuroscientist and international authority on visual perception, has been selected to receive the 2015 Verriest Medal from the International Colour Vision Society for his contributions to understanding the structural and functional basis of color vision, how and why vision changes across the life span, and factors that contribute to loss of vision associated with disease. He will receive the award at the society's biennial symposium in Sendai, Japan, in July.
