Eyelid Surgery: Eyelid surgery, also known as blepharoplasty, is perhaps the most common type of oculoplastic procedure. It involves the removal of excess skin, fat, or muscle from the eyelids to correct drooping lids and puffy bags. Tear Duct Surgery: When tear ducts are blocked or damaged, it can cause chronic tearing or infections. Tear duct ...
A silastic tube or stent may be employed along with probing to maintain tear duct patency. [6] A systematic review comparing immediate probing with deferred probing found that in children with unilateral nasolacrimal duct obstruction, immediate probing resulted in a higher success rate of treatment compared to deferred probing. [7]
Tears are produced by the lacrimal gland, situated just outside the eye. Blinking the eyelids distributes the tears to keep the eyes moist, clean and lubricated. Excess tears are drained via the punctum through the tiny channels called canaliculi located on the inner side of the eyes into the tear sac, from there to the tear duct, the nose and finally down the throat.
A dacryocystorhinostomy (DCR) or dacryocystorhinotomy is a procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function. [8] [11] A dacryocystostomy is an incision into the lacrimal sac, usually to promote drainage. [8] A dacryocystotomy is an incision into the lacrimal sac. [8]
Atrophic rhinitis is an absolute contraindication. In case of acute dacryocystitis, this operation can not be done immediately, rather it is done after a period of time. In case of elderly patients (above 70 years of age), dacryocystectomy is preferred to dacryocystorhinostomy as old age naturally causes atrophy in nasal mucosa.
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture. During an ear infection, excess mucus may drain through the nasolacrimal duct in the opposite way tears drain. [citation needed] In humans, the tear ducts in males tend to be larger than the ones in ...
In each eye, there are two puncta [59] – little openings that drain tears into the tear ducts. [4] There are methods to partially or completely close the tear ducts. [16] This blocks the flow of tears into the nose, and thus more tears are available to the eyes. [13] Drainage into either one or both puncta in each eye can be blocked.
Causes of epiphora are any that cause either overproduction of tears or decreased drainage of tears, resulting in tearing onto the cheek. [2] This can be due to ocular irritation and inflammation (including trichiasis and entropion) or an obstructed tear outflow tract, which is divided according to its anatomical location (i.e., ectropion, punctal, canalicular or nasolacrimal duct obstruction).
