We defined a DITC as the condition where at least 1 trocar cannula could not be inserted into the vitreous at the beginning of MIVS. The incidence of DITC was calculated from 1,525 eyes, and the pre-operative demographics of the DITC cases were compared to those of the non-DITC cases. <i>Results:<\/i> The incidence of DITC for all cases was 0.6% (9 of 1,525 eyes). Overall, there were 242 eyes with a retinal detachment (RD), and 8 of the 9 eyes with DITC had an RD with an incidence of 3.3% (8 of 242 RD eyes). Seven of these 8 eyes had a total RD, 4 also had a choroidal detachment, 4 eyes were also myopic (>\u20138.0 dpt, high myopia), and 6 of the 8 eyes were hypotonic (<8 mm Hg). The DITC cases had larger RDs (p < 0.0001), a higher incidence of choroidal detachment (p < 0.0001), higher myopia (p = 0.0204) and hypotony (p = 0.0003) than the non-DITC eyes with an RD. <i>Conclusions:<\/i> A large RD, a choroidal detachment, high myopia and hypotony are significant risk factors for DITC. We recommend that MIVS should be performed cautiously for eyes with these risk factors.<\/jats:p>","DOI":"10.1159\/000330745","type":"journal-article","created":{"date-parts":[[2011,10,27]],"date-time":"2011-10-27T07:31:05Z","timestamp":1319700665000},"page":"198-204","source":"Crossref","is-referenced-by-count":5,"title":["Difficulty in Inserting 25- and 23-Gauge Trocar Cannula during Vitrectomy"],"prefix":"10.1159","volume":"226","author":[{"given":"Hiroshi","family":"Kunikata","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumihiko","family":"Nitta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiko","family":"Meguro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoko","family":"Aizawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takehiro","family":"Hariya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Chiba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiaki","family":"Abe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kohji","family":"Nishida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2011,9,2]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2FS0161-6420%2802%2901179-X"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2FS0161-6420%2802%2901119-3"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097%2F00006982-200502000-00015"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1136%2Fbjo.2006.106799"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097%2FIAE.0b013e31817b98ba"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097%2FIAE.0b013e3181aa0f5f"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1038%2Feye.2010.41"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000093081"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1600-0420.2007.01012.x"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajo.2006.05.057"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3341%2Fkjo.2008.22.2.100"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajo.2007.03.046"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1136%2Fbjo.2007.133462"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajo.2008.04.010"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ophtha.2007.02.020"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097%2FIAE.0b013e318195cb28"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097%2FIAE.0b013e3181b32ebf"}],"container-title":["Ophthalmologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/330745","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/330745","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:32:31Z","timestamp":1745433151000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000330745"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":17,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2011,10,1]]},"published-print":{"date-parts":[[2011,10,27]]}},"URL":"https:\/\/doi.org\/10.1159\/000330745","archive":["Portico"],"relation":{},"ISSN":["0030-3755","1423-0267"],"issn-type":[{"type":"print","value":"0030-3755"},{"type":"electronic","value":"1423-0267"}],"subject":[],"published":{"date-parts":[[2011]]}}}
