Search for lymphatic drainage of the monkey orbit
Colloid solutions of technetium Tc-99m and india ink injected into the retrobulbar space of the cynomolgus monkey outside the extraocular muscle cone were removed from the orbit by the lymphatic vessels of the conjunctiva and eyelids and were then concentrated within the lymph nodes that drained the conjunctival and eyelid areas. Colloid solutions injected into the retrobulbar space inside the extraocular muscle cone did not reach the conjunctiva and did not collect in any lymph nodes over a 24-hour period. Within the orbit, the injected colloids spread along the planes of the connective-tissue septa. No lymphatic vessels were identified within the orbits posterior to the conjunctiva. Small amounts of india ink left the posterior orbit and ultimately entered the contralateral orbit. This posterior pathway did not lead to lymphatic vessels or lymph nodes and therefore does not appear to represent a prelymphatic pathway.
