Decomposing tears in order to detect Dry Eye Disease
By measuring proteins in tears, ophthalmologists can more easily diagnose dry eyes (Dry Eye Disease). Peter Raus, a Belgian ophthalmologist and PhD student at the Institute of Biology Leiden, developed a new method for protein determination in tear fluid. The technique is also promising for the early…
