What are Canalicular lacerations?
What are Canalicular lacerations?
Canalicular trauma refers to sudden physical injury that results in damage to the lacrimal drainage system of the eye. The lacrimal canaliculi are located within the medial aspect of the eyelid. This area area is unlike the rest of the eyelid because it does not contain a tarsal substructure.
How is canaliculitis treated?
Treatment of canaliculitis is warm compresses, irrigation of the canaliculus with antibiotic solution (by an ophthalmologist), and removal of any concretions or foreign bodies, which usually requires surgery (often done in the office with a local anesthetic).
What is the canaliculus in the eye?
The canaliculus (plural, canaliculi) is a short channel near the inner corner of the eyelid through which tears drain into the tear sac. (Each eye has two canaliculi, one for the upper eyelid and one for the lower.)
Where is the lacrimal Canaliculus located?
eyelid
The lacrimal canaliculi, (sing. canaliculus), are the small channels in each eyelid that drain lacrimal fluid, from the lacrimal puncta to the lacrimal sac. This forms part of the lacrimal apparatus that drains lacrimal fluid from the surface of the eye to the nasal cavity.
How do you pronounce Canalicular?
noun, plural can·a·lic·u·li [kan-l-ik-yuh-lahy].
Why is my Caruncle swollen?

How do you unclog a tear duct at home?
Place a clean index finger between the inner corner of the eye and the side of the nose. Gently slide the index finger downwards while massaging the side of the nose. You can repeat it around 10 times in the morning and 10 times at night. You may also use warm compresses to relieve itching and irritation.
What does lacrimal fluid lubricate?
It secretes lacrimal fluid (tear fluid), a watery fluid isotonic to plasma, onto the surface of the eyeball. This fluid forms the aqueous portion of a multilayered tear film that lubricates, protects and provides nutrients to the conjunctiva and cornea. When produced in excess, lacrimal fluid forms tears.
What is the superior canaliculus?
The superior lacrimal canaliculus ascends at first, bends at an acute angle, then passes medially and downward to the lacrimal sac. The inferior lacrimal canaliculus is larger and longer than the superior duct, it descends at first, then passes almost horizontally to reach the lacrimal sac.
What do you mean by lamellae?
A lamella (plural: “lamellae”) in biology refers to a thin layer, membrane or plate of tissue. This is a very broad definition, and can refer to many different structures. All the thylakoids of a granum are connected with each other, and the grana are connected by intergranal lamellae.
