|
Hot compresses and massage, most infants will require probing. you can also use upward massage to open the punctum.
|
|
what is the result of a failure of the nasolacrimal duct to completely canalize during gestation? And what could it cause as a secondary problem?
|
Congenital nasolacrimal duct obstruction, and it could cause bacterial dacryocystitis and or conjuctivitis, because the tears are held in the canals allowing bacteria to grow.
|
|
How do you manage a congenital nasolactimal duct obstruction?
|
warm compresses bid to qid, also use a topical antibiotic such as erythromycin bid for one week if there is a mucopurulent discharge. also have parents massage downward to open valve of hasner. If it doesn't resolve spontaneously by the age of 6 to 13 months probe it.

how could you test for Acquired nasolacrimal duct obstruction?
|
Jones test
|
|
Acquired nasolacrimal duct obstruction could often lead to?
|
Acute dacryocystitis. (inflammation of lac sac).
|
|
How do you treat Acquired nasolacrimal duct obstruction?
|
first try warm compresses, a topical antibiotic- steroid if there is partial obstruction.
If this is not successful then turn to surgery. Dacryocystorhinostomy (DCR). the insertion of a silicone tube (Jones tube). |
|
what type of bacteria cause the infection acute dacryocystitis?
|
staphylococci, streptococci, E. coli, pseudomonas, and other gram negatives.
|
|
what are some of the causes of nasolacrimal duct obstruction?
|
long and narrow nasolacrimal ducts, lacrimal sac diverticulum, trauma, dacryoliths (stone), or inflammatory sinus and nasal problems.
|
|
what would show as a tender red bump in the area inferior to the medial canthus? could extend about 2 cm below canthus.
|
Acute dacryocystitis
|
|
what is the treatment for Acute dacryocystitis?
|
-Warm compress tid,
-systemic antibiotic such as oral augmentin -also a topical antibiotic suchas erythromycin if conjunctivitis exists -aspirate the lacrimal sac contents with 19 gauge needle for culture testing. -could consider incision and drainage. - Consider dacryocystorhinostomy DCR. |
|
If the infection in the lacrimal region has no sign of being acute reactions it should be considered?
|
chronic daryocystitis
|
|
Which lobe of the lacrimal gland is affected more frequently?
|
the palpebral more than the orbital.
|
|
Most often Acute dacryoadenitis is caused by?
|
Acute dacryoadeitis is usually associated with systemic infections such as mumps, epsein barr virus and herpes zoster.
|
|
what is the diagnosis if the pt has temporal upper eyelid inflammation, sinusoidal lid tearing, discharge, fever, and possible proptosis
|
Acute Dacryoadenitis, the proptosis only occurs if the orbital lobe is involved (not often)

chronic dacryoadenitis - sarcoi
|
|
what is the triad of sjogrens syndrome?
|
dry eye, dry mouth and arthritis.
|
|
what is a possible diagnosis if there are no signs of inflammation but the globe is displaced. with enlargement of the lacrimal fossa?
|
lacrimal gland tumor.
|
|
what is the most common and the second most common etiology of canaliculitis?
|
1. actinomyces Israelii (filamentous grom + rod)
2. Candida albicans (yeast) |
|
Pt has erythema and swelling of punctum and adjacent tissues, also conjunctivitis around the medial canthus. What is a possible diagnosis.
