5 - 신선애외 : 눈물샘길질환의임상적고찰 - 방세포층 16 등다양하게보고되었으며, 대부분두층으로구성되어있으며, 만성화된낭종에서는단층으로구성되기도한다. 6 Jakobiec et al 20 은최근연구에서정상눈물샘소관과눈물샘소관낭포에는면역조직학적으로근상피세포가존재하지않으며, 따라서눈물소관낭포의발생이눈물소관의신경근수축의실패와관련된다는가설은맞지않다고보고하였다. 저자의경우조직검사를시행한눈물소관낭포 2안과눈물샘세관염 1안중, 눈물소관낭포 1안에서는정상눈물소관, 나머지 1안은입방상피세포로구성된단순낭종, 눈물샘세관염 1안은위상피성과형성소견을보였다. 치료로는눈물소관낭포는주사침배액술이나완전절제술또는조대술을시행할수있다. 주사침배액술이나인위적인파열술및부분적절제술은재발이흔하고, 완전절제술의경우주위정상눈물샘조직이손상될경우눈물샘분비능의변화로안구건조증을초래할수있다. 1-9 반면조대술은낭종의완전절제술로인한이차적인눈물샘분비능의저하의위험성을줄이면서비교적양호한치료성적이보고되어 1,3-6,21 저자의경우눈물소관낭포의치료로조대술을시행하였다. 눈물길결석에의한눈물샘세관염의치료로는위상피절제후결석과내용물을제거하였는데 6예중 3예에서속눈썹이함께발견되었다 (Fig. 3). 수술후모든예에서재발은없었으며안구건조증등의불편감도보이지않았다. 눈물샘길질환은임상적으로흔하지않지만눈꺼풀또는눈물샘와에생긴낭종의감별진단에고려해보아야할중요한질환으로 5 임상특징, 해부학적위치및검사를통해확진할수있다. 눈물소관낭포의자연관해는보고되지않았으며, 6 환자들은만성결막염, 다래끼등으로오인하여오랫동안치료받고불편함을호소하는경우가많다. 눈물소관낭포또는눈물샘세관염은국소마취를통한비교적간단한수술적방법으로완치될수있으므로임상적으로눈물샘길질환이의심되는환자에서빠르고정확한진단과치료가필요할것으로생각된다.

Methods: A retrospective chart review of 11 patients (11 eyes, 5 males, 6 females) diagnosed with lacrimal ductal disease between March 2007 and April 2013 was performed. Results: Among 11 eyes in 11 patients, 4 were diagnosed with dacryops and 7 with lacrimal gland ductulitis initiated by dacryolith. The mean age of the subjects was 47.9 years (range, years). Lacrimal gland ductulitis patients received treatment for conjunctivitis or hordeolum for several months. Four cases involved the right eye and 7 cases involved the left eye. Symptoms included foreign body sensation, pus-like discharge and palpable mass. Biopsy was performed in 3 cases and showed no specific findings. Patients with dacryops underwent marsupialization, whereas patients diagnosed with lacrimal gland ductulitis underwent excision and dacryolith curettage. During the 2-month follow-up period, all cases showed no signs of recurrence or complications. Conclusions: Lacrimal gland ductal disease can be mistaken for other diseases such as conjunctivitis, hordeolum, or orbital cyst, thus requiring accurate diagnosis and appropriate management.
