The lacrimal canaliculi form the first part of the nasolacrimal drainage apparatus that drains tears produced by the lacrimal gland.
Gross anatomy
There are two lacrimal canaliculi - superior and inferior on each side. They commence at the superior and inferior lacrimal puncta, which drain tears from the lacrimal lake that lies at the medial angle of the eye. They unite to form a common canaliculus and drain via the sinus of Maier into the lacrimal sac posterior to the medial palpebral ligament and anterior to the orbicularis oculi muscle. It is approximately 10 mm in length.
