The cause of dry eye syndrome, which affects millions of people around the globe on a daily basis, has been visually identified by experts in the US.
Scientists at Harvard Medical School have published new research in the Journal of Leukocyte Biology which suggests that natural killer (NK) cells promote inflammatory responses in dry eyes at both the ocular surface and the eye-draining lymph nodes.
This study is the first to identify the NK cells and helps to shed light on a condition which affects the lives of people across the planet, said Dr Yihe Chen, a researcher from the Schepens Eye Research Institute at the Massachusetts Eye and Ear Infirmary of the Department of Ophthalmology.
"Our study has promoted the further understanding of the pathogenesis of dry eye disease," the expert added.
Meanwhile, recent research carried out at the Cincinnati Children"s Hospital Medical Center into curing retinal damage could also lead to new cancer treatments, experts claim.
