Scientists Discover Hidden Cleanup System in the Eye

Researchers from the University of British Columbia and the University of Toronto have uncovered a previously unknown drainage system at the back of the eye, termed the posterior ocular lymphatic outflow (POLO) pathway. This hidden system, demonstrated in mice, drains fluid and waste into the body's lymphatic network, challenging existing assumptions about eye function and potentially leading to new treatments for conditions like glaucoma and macular degeneration.
