Anatomical dissections were performed on eight fixed cadavar orbits to observe the relationship of the pretarsal, preseptal, and Horner's muscle to the canaliculus. The attachments of Horner's muscle and the deep preseptal muscle to the lacrimal diaphragm reflected their important role in the lacrimal diaphragm's function. In addition, the muscles involved in lacrimal drainage were mechanically pulled with a forceps to induce canalicular pressures. Shortening and compression of the canaliculus by the pretarsal, preseptal, and lateral Horner's muscle increased canalicular pressure, whereas Horner's muscle and the deep preseptal muscle induced negative lacrimal pressures. A positive-to-negative pressure gradient in the lacrimal drainage system was proposed as the main force in lacrimal tear transport.
对八个固定的尸体眼眶进行解剖，以观察睑前、睑板前和霍纳肌与泪小管的关系。霍纳肌和睑板前深层肌肉在泪膈上的附着反映了它们在泪膈功能中的重要作用。此外，用镊子机械牵拉参与泪液引流的肌肉以诱导泪小管压力。睑前、睑板前和外侧霍纳肌对泪小管的缩短和压迫增加了泪小管压力，而霍纳肌和睑板前深层肌肉则产生负泪压。泪液引流系统中从正压到负压的压力梯度被认为是泪液运输的主要力量。
