title: [The region of the origin of the m. obliquus bulbi inferior].
abstract: A small depression usually develops immediately laterally to the entrance to the nasolacrimal canal, for the origin of the inferior oblique muscle. This depression is generally a part of the maxilla. In fetal material it was found that the development of this zone and of the lacrimal bone involves a more complex process than indicated in textbooks. In adults the inferior oblique muscle rises 1.54 mm (mean) laterally to the entrance to the canal and only 0.473 mm behind the inferior orbital rim of this area. The mean width of this muscle at its origin is 3.93:2.26 mm. The location of the muscle origin in relation to the orbital septum, its vascularization and possible causes of damage to its origin are pointed out.
