Three serial sections from 2 additional eyes were cut in the coronal plane at the level of the ciliary body and immunofluorescence double\u2010stained with Lyve\u20101 and CD31 to map lymphatic channel distribution.

Both of the coronally sectioned globes had Lyve\u20101\u2013positive lymphatic\u2010like structures in the ciliary body.

This could indicate the presence of a novel uveolymphatic outflow pathway, which may play a role in aqueous humor outflow. Future studies are needed to confirm the existence and elucidate the role of this proposed uveolymphatic outflow pathway and potentially develop novel treatment options for managing
