Midterm 2- Lacrimal disease Flashcards
Congenital Dacryocele
- Collection of amniotic fluid within an obstructed lacrimal sac
- Appears as a firm bluish mass on the side of the nose and inferior to the medial canthus of the eyelid
- Hot compresses and massage is the initial treatment but most infants will require probing
Congenital Nasolacrimal Duct Obstruction
- A very common disorder in infants; occurs clinically in 2-4% full-term infants
- Results from a failure of the nasolacrimal duct to completely canalize during gestation
- Usually the obstruction is at the nasal end, the “valve” of Hasner
- Unilateral or bilateral
- Most common cause of tearing in childhood
- Can lead to a bacterial dacryocystitis and conjunctivitis
Congenital Nasolacrimal Duct Obstruction signs
Tearing
Discharge
Crusting
Mucus reflux from the punctum with compression over the lacrimal sac
Congenital Nasolacrimal Duct Obstruction management
- Warm compresses bid to qid
- Topical antibiotic ointment (erythromycin bid for 1 week) if mucopurulent discharge
- Massage bid to qid - parent places index finger over infant’s canaliculi (medial corner of eyelid) and makes several slow downward strokes
- -The motion will send hydrostatic forces down the nasolacrimal duct to open the obstruction
Congenital Nasolacrimal Duct Obstruction tx
- Over 90% of nasolacrimal obstruction will resolve spontaneously or with the assistance of nasolacrimal duct massage
- Probing is considered between 6 and 13 months of age; exact timing for probing is controversial
- If probing is not successful, treatment is usually surgical
Congenital Glaucoma
DDx congenital tearing
If the child has both
tearing and photophobia, the possibility of congenital glaucoma should be considered, even if the cornea is not cloudy or large
Congenital Glaucoma signs
Large horizontal iris diameter
HVID- horizontal visible iris diameter
Structural changes in eye
Acquired Nasolacrimal Duct Obstruction etiology
Chronic sinus disease
Age-related stenosis
Naso/orbital trauma
Acquired Nasolacrimal Duct Obstruction findings
Tearing
Discharge
Crusting
Recurrent conjunctivitis
Acquired Nasolacrimal Duct Obstruction dx
Jones test(s) Often leads to acute dacryocystitis
Acquired Nasolacrimal Duct Obstruction management
- Warm compresses
- Topical antibiotic-steroid if partial obstruction
- Dilation/irrigation and/or probing
- If not successful, management is usually surgical
- -Silicone intubation
- -Dacryocystorhinostomy (anastomosis between lacrimal sac and nasal cavity)
Acute Dacryocystitis
Infection of the lacrimal sac
Acute Dacryocystitis
Etiology
Nasolacrimal duct obstruction
Tears stagnate in lacrimal sac
Become infected
Acute Dacryocystitis
causes
Causes of nasolacrimal duct obstruction Long and narrow nasolacrimal ducts Lacrimal sac diverticulum Trauma Dacryoliths- stones formation Inflammatory sinus and nasal problems
Acute Dacryocystitis infection
Bacteria causing infection
- Staphylococci
- Streptococci
- E. coli, Pseudomonas, other Gram negatives
Acute Dacryocystitis findings
- Tenderness, erythema, and swelling over nasal portion of lower eyelid
- Epiphora
- Purulent punctal discharge particularly if pressure is applied to the lacrimal sac
- Fever and malaise may occur
Acute Dacryocystitis
Complications
- Preseptal cellulitis
- Conjunctivitis
- Cutaneous fistulas may form from the lacrimal sac
- Less common, orbital cellulitis and sepsis
Acute Dacryocystitis tx
-Warm compress tid
-Systemic antibiotic
Oral Augmentin (amoxicillin/clavulante)
IV Unasyn (amoxicillin/sulbactam)
- Topical antibiotic ointment (erythromycin) if conjunctivitis exists
- Aspirate lacrimal sac contents with 19 gauge needle for culture and susceptibility testing
