It was reported that the coronal approach was complex and time-consuming for unilateral cases without craniomaxillofacial fractures.[sup], To treat the upper nasolacrimal
duct obstruction or absence, CDCR with a tear drainage tube placement is an appropriate surgical method.

occlusion, eyelid closure, or blotting the excess drops away during administration and punctual plugging should be discussed with pregnant women on topical anti-glaucoma medications.
Because of the low time of residence of the drug on the ocular surface have it minimally absorbed into the eye (210%), but a systemic effect can be induced by the network of conjunctival vessels and via the nasolacrimal
duct through the highly vascularised nasal mucosa and may be swallowed and absorbed via the stomach (16).
(2) The tears drain into the conjunctival sac on the bulbar surface of the lower lid and then exit via the inferior and superior nasolacrimal
puncta at the medial canthus.
For children who present to your office, consider "anything that can go wrong to make the eye red," he continued, including nasolacrimal
duct obstruction, adnexal disease, foreign body/trauma, uveitis, neoplasm, structural change, or conjunctivitis.
duct obstruction--An obstruction of the nasolacrimal
(1995) reported good occlusion results when n-butylcyanoacrylate was used on the lacrimal punctum and nasolacrimal
duct of humans, respectively; however, no information was provided on local tissue damage.
