What is a Dacryocystography?

Dacryocystography is used to diagnose the condition causing problems with your tear duct. This is a minimally invasive procedure that is performed on an out-patient basis. You will receive an injection of contrast medium, which will allow the interventional radiologist to clearly visualise the lacrimal sac under X-ray.

How do you do Dacryocystography?

Dacryocystography/lacrimal scan With the patient lying down, a drop of topical anesthetic is placed in the palpebral aperture. Both lower puncta are simultaneously intubated and injected with low-viscosity oil. Serial radiographs are taken during injection. The lacrimal scan is the most physiologic test to date.

Why is Dacryocystography important for evaluation of the eye?

Dacryocystography allows the identification of the obstruction site and, in some cases, the cause of the obstruction of tear flow, which is fundamental to define the type of clinical or surgical conduct. With an experienced physician, the examination is only slightly uncomfortable.

What is a Dacryocystorhinostomy procedure?

Dacryocystorhinostomy (DCR) surgery is a procedure that aims to eliminate fluid and mucus retention within the lacrimal sac, and to increase tear drainage for relief of epiphora (water running down the face).

What is a Dacryolith?

A dacryolith is a concretion within the lacrimal drainage system. Although it may cause intermittent epiphora without inflammation, dacryoliths are often underlying contributors to recurrent or chronic dacryocystitis. It may occur anywhere along the lacrimal drainage system, albeit most commonly in the lacrimal sac.

Which bone is cut in DCR surgery?

Kerrison rongeurs or a high-speed drill are used to remove the bone of the lacrimal fossa, inferiorly to the lacrimal duct at the inferior orbital rim, and anteriorly past the anterior lacrimal crest.

Which bones are cut in DCR?

DCR is an operation whereby the lacrimal sac is drained into the nose via a bypass conduit called the ostium or rhinostomy as an opening is made in the lacrimal fossa and ascending process of the maxilla, which is lined with lacrimal sac and nasal mucosa.

Why is Dacryocystorhinostomy performed?

How successful is Dacryocystorhinostomy surgery?

In conclusion, the success rate of external DCR was 98.8% anatomically and 81.9% functionally in a large case series with primary lacrimal drainage obstruction.

What causes Dacryolith?

Several predisposing factors related to dacryolith formation have been suggested, such as chronic obstruction and inflammation of the lacrimal sac, facial trauma, bacterial or fungal infection, a foreign body such as an eyelash, cigarette smoking, congenital anomalies of the Hasner’s valve, dehydration, and alterations …

How do you remove Dacryolith?

Results: Methods to extract dacryoliths include minimally invasive techniques such as nonsurgical radiologic or endoscopic removal during dacryoplasty or surgical approaches such as external or endonasal dacryocystorhinostomy.

What is DCG in the army?

The PCG is an armed and uniformed service tasked primarily with enforcing laws within Philippine waters, conducting maritime security operations, safeguarding life and property at sea, and protecting marine environment and resources; similar to coast guards around the world.

What do CDG mean?

CDG stands for Congenital Disorders of Glycosylation. CDG is a large group of rare inherited diseases affecting glycosylation.

How is the tube removed after a DCR?

The tube is simply removed externally by grasping it at the medial canthus with non-toothed forceps and firmly pulling laterally in a single movement (Figure 1c). This obviates the need of any intranasal manipulation or tube cutting. The short sleeve segment rests within the nose before finding its own way out.
