Bilateral dacryocystitis complicated by unilateral retrobulbar abscess in a five-week-old infant

The Safety and Efficacy of Endoscopic Lacrimal Duct Probing in Neonates with Acute Dacryocystitis

“…The pathogenesis is not caused by a single factor, and few factors affecting neonatal lacrimal sacculitis have been reported abroad [14]. Some scholars pointed out that in addition to Hasner flap obstruction of the inferior nasolacrimal duct, there are bony and epithelial obstructions [15]. It was found that the main risk factors for x neonatal dacryocystitis were gestational age <37 weeks, family history of rhinitis, cesarean delivery, family economic status, time of birth and birth weight >4 kg [16,17].…”

Orbital Abscess Secondary to Nasolacrimal Duct Obstruction in an Extremely Preterm Infant

“…8 Pediatric orbital cellulitis cases secondary to dacryocystitis that require surgical drainage are even more rare. 7,[15][16][17] In previous reports, drainage was performed via an orbitotomy, 8 incision of the lacrimal sac, 16 or endoscopically 7 with probing of the lacrimal system. In the current case, we chose to perform an inferior orbitotomy to allow access to both the lacrimal sac and medial orbit, allowing drainage of the large intraorbital abscess.…”

“…5 Orbital cellulitis secondary to dacryocystitis or dacryocystocele is even less common, with only a few cases reported in infants, children, or adults. [7][8][9] Herein, the authors present a case of an orbital abscess secondary to nasolacrimal duct obstruction and dacryocystitis in an extremely preterm infant. This case report adhered to the tenets of the Helsinki Declaration, and written consent was obtained for the use of all clinical data and images.…”

Orbital involvement in lacrimal drainage disorders

“…Posterior extension in the form of orbital cellulitis and orbital abscess can happen if the posterior barriers weaken. [ 2 15 16 17 18 19 20 21 22 23 24 25 26 27 ] Various theories for posterior extension of acute dacryocystitis have been suggested. Repeat episodes of acute dacryocystitis can cause distension of the soft tissues, and hence, weaken the posterior barriers, which then predisposes to orbital spread of the infection.…”
