Evidence for Lymphatics in the Developing and Adult Human Choroid [Retinal Cell Biology]

Conclusions. The system of blind-ended initial lymphatic segments seen just external to the fenestrated vessels of the choriocapillaris is ideally placed for recirculating extracellular fluid and strategically placed for immune surveillance. The presence of a system of lymphatic-like channels in the human choroid provides an anatomical basis for antigen presentation in the posterior eye, with a possible route from the eye to the sentinel lymph nodes, similar to that already described for anterior eye lymphatics.
