The transmitted light helps illuminate and delineate the trajectory of Schlemm\u2019s canal. This aids in guiding the trabeculotome and reduces the likelihood of false passages into the anterior chamber. This innovative method is simple, feasible, and more affordable compared to illuminated microcatheter systems such as iTrack, which are costly and often unavailable in resource-limited settings.\n                      <jats:sup>[5-7]<\/jats:sup>\n                      The light pipe provides enhanced visualization of the canal path, facilitating safer and more precise trabeculotomy. However, limitations include the inability to visualize the cut ends of Schlemm\u2019s canal and the relatively larger diameter of the light pipe compared to the canal, restricting its use in smaller canals, with the possibility of false passages.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights:<\/jats:title>\n                    <jats:p>The light pipe-guided technique offers a practical and effective alternative for canal tract identification in challenging trabeculotomy cases, with potential to improve surgical outcomes in congenital glaucoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Video link:<\/jats:title>\n                    <jats:p>https:\/\/youtu.be\/8vvpmuaWkNw<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/ijo.ijo_838_25","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T14:03:40Z","timestamp":1790690620000},"page":"1565-1566","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Illuminate the concealed: An innovative method to identify the path of Schlemm\u2019s canal"],"prefix":"10.4103","volume":"74","author":[{"given":"Bhawesh C","family":"Saha","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, All India Institute of Medical Sciences, Patna, Bihar, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rashmi","family":"Kumari","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Indira Gandhi Institute of Medical Sciences, Patna, Bihar, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Indira Gandhi Institute of Medical Sciences, Patna, Bihar, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"R1-20261007","doi-asserted-by":"crossref","first-page":"459","DOI":"10.1038\/sj.eye.6702223","article-title":"Success of trabeculotomy in patients with congenital glaucoma operated on within 3 months of birth","volume":"21","author":"Yalvac","year":"2007","journal-title":"Eye (Lond)"},{"key":"R2-20261007","doi-asserted-by":"crossref","first-page":"715","DOI":"10.1136\/bjophthalmol-2014-305164","article-title":"Technique for identifying Schlemm\u2019s canal in paediatric glaucoma surgery","volume":"99","author":"Medsinge","year":"2015","journal-title":"Br J Ophthalmol"},{"key":"R3-20261007","doi-asserted-by":"crossref","first-page":"414","DOI":"10.3390\/jcm11020414","article-title":"Microcatheter-Assisted Circumferential Trabeculotomy in Primary Congenital Glaucoma: Long-Term Clinical Outcomes","volume":"11","author":"Fontana","year":"2022","journal-title":"J Clin Med"},{"key":"R4-20261007","doi-asserted-by":"crossref","first-page":"316","DOI":"10.4103\/sjopt.sjopt_313_24","article-title":"Microcatheter-assisted trabeculotomy in the treatment of primary congenital glaucoma: Current perspectives","volume":"38","author":"Al Habash","year":"2024","journal-title":"Saudi J Ophthalmol"},{"key":"R5-20261007","first-page":"1","article-title":"360-degree trabeculotomy using illuminated microcatheters improves safety and reduces misdirection compared with traditional techniques","volume":"28","author":"Beck","year":"2019","journal-title":"J Glaucoma"},{"key":"R6-20261007","doi-asserted-by":"crossref","first-page":"145","DOI":"10.4103\/meajo.MEAJO_317_20","article-title":"Surgical Outcomes of Microcatheter-assisted Trabeculotomy as a Secondary Procedure in Patients with Primary Congenital Glaucoma","volume":"27","author":"Al Habash","year":"2020","journal-title":"Middle East Afr J Ophthalmol"},{"key":"R7-20261007","article-title":"iTrack 250 microcatheter description and intraoperative illumination benefits","year":"2007","journal-title":"Glaucoma Today"}],"container-title":["Indian Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_838_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T07:00:50Z","timestamp":1791356450000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_838_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,29]]},"references-count":7,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.4103\/ijo.ijo_838_25","relation":{},"ISSN":["0301-4738","1998-3689"],"issn-type":[{"value":"0301-4738","type":"print"},{"value":"1998-3689","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,29]]}}}
