Orbital septa: anatomy and function

Ophthalmology. 1979 May;86(5):876-80. doi: 10.1016/s0161-6420(79)35444-6.


As a consequence of some puzzling motility disturbances in patients with blow-out fractures, a new anatomic approach to the human orbit was developed. This new approach revealed unknown connective tissue septa inside the orbit. These connective tissue septa were highly organized and formed an accessory locomotor system. This system is involved in pathologic circumstances like blow-out fractures and can account for the motility disturbances in these cases; additionally, it plays an important, yet to be unravelled, role when normal eye movements are performed.
