What does Dacryocystitis mean?
Dacryocystitis is an infection or inflammation of the nasolacrimal sac, usually accompanied by blockage of the nasolacrimal duct. Dacryocystitis can be acute or chronic and congenital or acquired. When present, medial canthal swelling of dacryocystitis is usually located below the medial canthal tendon.
What is endoscopic Dacryocystorhinostomy?
Dacryocystorhinostomy is the preferred surgical solution for cases of nasolacrimal duct obstruction. The procedure involves the creation of an alternative pathway between the lacrimal sac and the nasal cavity, resulting in the bypass of the duct and allowing tears to be drained directly into the nasal cavity.
How is eye and nose connected anatomically?
Though sight and smell are two very different senses, the eye and nose are intimately connected by the nasolacrimal apparatus, the drainage system that carries tears from the ocular surface to the nose and ultimately to the gastrointestinal tract. The interconnected nature of the nasolacrimal system.
Can something go up your nose to your eye?
It would be virtually impossible for a nasally administered drug to reach the eye directly, as the vast majority of a drug does not reach that high and what does is cleared downward to the throat.
What is the pink thing in the corner of your eye?
The lacrimal caruncle, or caruncula lacrimalis, is the small, pink, globular nodule at the inner corner (the medial canthus) of the eye. It consists of tissue types of neighbouring eye structures.
How is a DCR performed?
Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. It may be performed through an external skin incision or intranasally with or without endoscopic visualization.
What is nasolacrimal stent?
Nasolacrimal stents are small diameter tubes placed within the nasolacrimal system to maintain patency.
Can your sinuses drain through your eyes?
If you blow your nose and the nose is congested- or hold the nose too tightly when you blow- mucus from the nose can go the other way- through the tear ducts and around the eye. This is likely what is going on in your case.
Can a deviated septum affect your eyes?
The septum is the bone and cartilage that divides your nose in half. A deviated or displaced septum may cause snoring, nosebleeds, create difficulty breathing, and can also cause recurrent sinus infections which can be painful and even disrupt your vision.
Can a foreign object get stuck behind the eye?
A foreign object that lands on the front part of the eye cannot get lost behind the eyeball, but they can cause scratches on the cornea. These injuries usually are minor. However, some types of foreign objects can cause infection or damage your vision.
Can sinus drainage come out eyes?
How are eye problems solved through the nose?
Solving Eye Problems Through the Nose. The source of the problem is often the tear sac, the first collecting point for tears on their way into the nose, or the duct that carries the tears from the sac into the nasal passage. A common surgery to repair tearing is to bypass the duct by making an opening directly from the sac into the nose,…
What are the passages between the eye and nose called?
The passages between eye and nose containing the canaliculi, lacrimal sac and nasolacrimal ducts represent something of a no man’s land between the ophthalmic and the ear, nose and throat specializations, but maintaining vigilance on both ends can ensure the appropriate identification and treatment of problems in the middle.
How do tears travel from eye to nose?
We’ll take a moment here to review the exact pathway tears take to travel from eye to nose. Once tears have been secreted from the main and accessory lacrimal glands and distributed evenly over the ocular surface by the eyelids, they are then passed into the nose through the lacrimal drainage system beginning with the upper and lower puncta.
Why is it important to maintain a close connection between eyes/noses?
It’s important to maintain an awareness of the close connection between the eye and nose: To some degree, what you are doing to the eye you are also doing to the nose, and what you’re doing to the nose you’re doing systemically.
