Nasolacrimal duct anomaly in calves.

Supernumerary openings of the nasolacrimal drainage apparatus were found in 13 Brown Swiss calves. The cause of the anomaly was not determined but was assumed to be similar to that in man.

Probing and bicanalicular silicone tube intubation under nasal endoscopy in congenital nasolacrimal duct obstruction.

PURPOSE: To evaluate the beneficial effects of nasal endoscopy on preventing complications during probing and bicanalicular silicone intubation, and to determine the structural nasal abnormalities in congenital nasolacrimal duct obstruction. METHODS: Probing and silicone tube intubation under nasal endoscopy were performed in 37 eyes of 26 patients who ranged in age from 7 to 60 months (mean, 18.8 +/- 13.4 months). RESULTS: By nasal endoscopy, the inferior turbinate and meatus appeared normal in 15 patients (58%), whereas 11 patients (42%) had hypertrophy of the inferior turbinate and/or stricture in the inferior meatus. Twenty-four of 26 eyes (92%) were cured by probing only. We performed silicone tube intubation and cured 11 of 12 eyes (92%) including two failures. Of 14 eyes that had undergone failed probings elsewhere, the success rate was 92.8% (13 of 14 eyes). The overall success rate of probing and silicone tube intubation under nasal endoscopy was 97%. CONCLUSION: Nasal endoscopy during probing and bicanalicular silicone tube intubation is useful especially in selected cases of failed probings. Nasal endoscopy should assist the inexperienced surgeon in preventing trauma to the nasal base and septal mucosa, hemorrhage, and passage of the probe under the mucosa rather than through the ostium.

Nasolacrimal duct obstruction following transantral-ethmoidal orbital decompression.

Of 200 patients undergoing bilateral transantral-ethmoidal orbital decompression for Graves' ophthalmopathy, nine suffered symptomatic postoperative obstruction of the lower nasolacrimal excretory system. Five of the nine patients had persistent symptoms of epiphora or repeated episodes of dacryocystitis that necessitated dacryocystorhinostomy. Dacryocystorhinostomy relieved symptoms and objective evidence of obstruction in these five patients. We believe that nasolacrimal duct obstruction occurred in these patients as a complication of nasoantral window construction.

[Results of endonasal intubation of the nasolacrimal duct in children with congenital dacryocystitis].

Results of endonasal catheterization of the naso-lacrimal canal of 74 children with congenital dacryocystitis (bilateral problem in 10 of them) are presented. Prior to this manipulation, the patients were exposed to contrast X-ray study of the lacrimal sac for diagnostic purposes. Retrograde catheterization as a method for treating congenital dacryocystitis was very good in 97.3% children of up to 2 years old, 50% children of up to 3 years old, and 33.3% children between 3-4 years old. The patency of the naso-lacrimal canal also recovered in an 8-year-old child. All this gives evidence that, irrespective of children's age, retrograde catheterization should be applied to treat congenital dacryocystitis. After the patency of the naso-lacrimal canal was restored, the external fistula of the lacrimal sac was cauterized with 7% solution of trichloroacetic acid.

Community-acquired methicillin-resistant Staphylococcus aureus in association with chronic dacryocystitis secondary to congenital nasolacrimal duct obstruction.

Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as an important pathogen responsible for serious ocular and systemic disease. MRSA has been reported to occur in dacryocystitis in the adult population. This is the first case report of community-acquired MRSA in the pediatric population in association with chronic dacryocystitis secondary to congenital nasolacrimal duct obstruction in an infant.

Intranasal visualization for nasolacrimal duct intubation.

PURPOSE/METHODS: To improve intranasal visualization of nasolacrimal procedures we use a self-retaining nasal speculum with or without a sinuscope. RESULTS/CONCLUSIONS: Placement and retrieval of silicone stents can be accomplished with less trauma than with a blind sweep technique. Additionally, the valve of Hasner can be seen and the creation of false passages avoided.
