Ab interno vs ab externo microcatheter‐assisted trabeculotomy for primary congenital glaucoma with clear cornea

Abstract

Ab interno approach provide good and comparable outcomes as ab externo approach for microcatheter-assisted trabeculotomy in primary congenital glaucoma eyes with clear cornea. It should be considered as the initial choice in these patients with the benefit of sparing conjunctiva. Successful trabeculotomy with either technique during the first attempt is critical to overall success and underscores the need for proficiency before independent practice.
