lacrimal sac

Lacrimal sac massage has been proposed as helping to open the duct, though this is not always successful.

The bone covering the lacrimal sac is nibbled out.

A dacryocystostomy is an incision into the lacrimal sac, usually to promote drainage.

"Maier's sinus": A depression in the internal surface of the lacrimal sac.

The inferior duct at first descends, and then runs almost horizontally to the lacrimal sac.

A dacryocystectomy is the surgical removal of a part of the lacrimal sac.

The upper part of the lacrimal sac is covered by the medial palpabral ligament.

These pass the tears on to the lacrimal sac, in turn to the nasolacrimal duct, which dumps them out into the nose.

The Lacrimal Sac also drains the eye of any debris, bacteria, dirt, etc.

Mucoepidermoid carcinoma can also be found in other organs, as bronchi, lacrimal sac and thyroid.

The operation can also be performed endoscopically through the nose where an opening is fashioned in the lacrimal sac from within the nose.

In this procedure, a nasal endoscope is used to visualise the lacrimal sac through the nasal cavity.

The fluid is conveyed to the lacrimal sac, and thence via the nasolacrimal duct to the inner nose.

Crossing the lacrimal sac, it divides into two parts, upper and lower, each attached to the medial end of the corresponding tarsus.

The upper part of this fossa lodges the lacrimal sac, the lower part, the nasolacrimal duct.

An incision used to release pus in the lacrimal sac in acute phlegmonous dacryocystitis.

The nasolacrimal duct (sometimes called the tear duct) carries tears from the lacrimal sac into the nasal cavity.

This is mainly for high amounts of tears, in which the lacrimal sac pumps inward and outward driven by the orbicularis muscle during blinking.

Regurgitation test, an eye test done by pressure over the lacrimal sac area and observing discharges coming out of puncta lacrimalia.

The lacrimal sac can be pictured by dacrocystography, which is injecting radiocontrast into it and performing X-ray imaging of it.

Dacryoliths or cast formation , within the lacrimal sac can also produce obstruction of the NLD.

A surgical procedure called a dacryocystorhinostomy is done to join the lacrimal sac to the nasal mucosa in order to restore lacrimal drainage.

Her lacrimal sacs emptied into the lacrimal lakes, which reached flood stage, and two more droplets sluiced a little misery out of her eyes.

Bloody punctal discharge or lacrimal sac distension above the medial canthal tendon is also highly suggestive of neoplasm.

Surgical indications include recurrent dacryocystitis, chronic mucoid reflux, painful distension of the lacrimal sac, and bothersome epiphora.
