Dacryostenosis
Treatment of Dacryostenosis
Manual or surgical decompression Treatment of underlying disorder Congenital nasolacrimal duct obstruction often resolves spontaneously by about age 6 to 9 months; before 1 year, manual compression of the lacrimal sac 4 or 5 times a day may relieve the obstruction. After age 1 year, the nasolacrimal duct may need probing, usually under general anesthesia; if obstruction is recurrent, a temporary silastic tube may be inserted. In acquired nasolacrimal duct obstruction, the underlying disorder is treated when possible. If treatment is not possible or is ineffective, a passage between the lacrimal sac and the nasal cavity can be created surgically (dacryocystorhinostomy). In cases of punctal or canalicular stenosis, dilation is usually curative. If canalicular stenosis is severe and bothersome, a surgical procedure (conjunctivo-dacryocystorhinostomy or C-DCR) that places a tube made of low thermal-expansion borosilicate glass (Jones tube) leading from the caruncle (the small, pink, nodule at the medial canthus) into the nasal cavity can be considered.
