Left Nasolacrimal Duct Research Articles

What's Your Diagnosis?

<h4>The Case</h4> <p>A 6-month-old infant presented for evaluation of anisocoria. At 1 month of age, a left nasolacrimal duct obstruction (NLDO) was recognized. Treatment with TobraDex ointment (Alcon, Fort Worth, TX) twice daily was started and continued until 5 months of age, when enlargement of the left cornea was noticed (Figure). Successful NLDO probing was then performed, and examination with anesthesia revealed an enlarged eye, anisocoria, intraocular pressure (IOP) of 30 mm Hg, and optic disc cupping on the left. A 2-month trial of medical glaucoma therapy failed, and a goniotomy was advised (S. Salim, MD, and D. S. Walton, MD, unpublished data, 2005). At 20 months after goniotomy, the IOP is well controlled without medication.</p>

Agenesis or hypoplasia of major salivary and lacrimal glands

We described a young man with almost total absence of the parotid glands, hypoplasia of both lacrimal glands, marked hypofunction of both submandibular glands, and left nasolacrimal duct atresia. Lack of tearing, severe dental caries, and conjunctival scarring following chronic xerophthalmia and conjunctivitis serve to alert pediatricians to this autosomal dominant disorder with considerable variation in expressivity.

ARGYROSIS OF THE CONJUNCTIVA AND LACRIMAL SAC.

This paper reports a patient with marked argyrosis of the conjunctiva and lacrimal sac. Only two reports 1,2 of argyrosis of the lacrimal sac have appeared in the English literature since de Schweinitz's original description in 1903. 3 Report of Patient A 66-year-old white woman who had used selfprescribed Argyrol (a mild silver protein preparation) over many years for recurrent mild conjunctivitis was first seen in consultation on Aug 1, 1963. She had known of an obstructed left nasolacrimal duct for one year and had continued the use of Argyrol eye drops. Her eyes were healthy except for findings in the conjunctiva and lacrimal apparatus. The conjunctiva showed typical discoloration of argyrosis bilaterally, which was most marked in the lower cul-de-sacs. The right nasolacrimal apparatus irrigated freely. Fluid injected through the left lower canaliculis, however, regurgitated through the upper, indicating an obstruction of the duct rather than the canaliculi. Nothing
