A system of electrotherapeutics as taught by the International correspondence schools, Scranton, . tery-Tip and Handle 2o ELECTRICITY IN DISEASES OF §18 the current as to bring the cautery-tip to a white heat. Thepatient should be anesthetized. If the lid is in a condition ofentropion, steady it by means of Knapps clamp and incise through the skin along themargin from the external can-thus to the punctilio lacri-mal well down to the tarsalcartilage. The incision shouldavoid injuring the hair-folli-cles. The operation in ectro-pion is similar with theexception that the affected lidis everted and the incisioncarried along its conjunctivalsurface. A second incisionparallel to the first and fartherfrom the palpebral bordermay be required (see Fig. 30).The after-treatment requirescooling compresses and band-ages to the eye. Ectropionand entropion due to atonyand atrophy of individual libers of the orbicularis palpebrarummay be benefited by faradization of the atrophied bundles withfine electrodes. Patiently continued for a long period thistreatment will restore the position of the • if ion In h DISEASES OF THE LACRIMAL APPARATUS STENOSIS OF THE LACRIMAL CANAL 35. In stenosis of the lacrimal canal the stricture mayoccur at any point along the passage, either at the punctum,in the canaliculus, or in the nasal duct. In the first-namedposition the condition generally arises from blepharitis, orconjunctivitis, in the second from an extension of inflam-matory processes or the presence of a minute foreign body, § 18 THE EYE, EAR, NOSE, AND THROAT 27 while a narrowing of the nasal canal depends as a rule onthe presence of long-continued nasal catarrh. The symptomcommon to all derangements of the lacrimal passage is theleaky eye. 36. In electrolysis we possess the most valuable of alltherapeutic agents in the treatment of this disorder. Theresults of its application show a greater number of cures and alesser number of relapses than with other methods. Theoperator m
