IMPACTT for Primary Congenital Glaucoma

Dr. Anil Kumar Mandal highlights details of the surgical technique termed illuminated microcatheter passage assisted circumferential trabeculotomy and trabeculectomy (IMPACTT) and its results on a 3-month-old child with advanced primary congenital glaucoma (PCG). With the help of an illuminated microcatheter ab externo, circumferential trabeculotomy was performed. The trabeculectomy is completed in the usual manner. In advanced cases of PCG, collector channels and distal outflow system are more likely to be malformed. In such a situation, angle surgery, even in the form of circumferential trabeculotomy, may prove to be suboptimal and necessitate addition of trabeculectomy that bypasses the distal outflow system. Hence, IMPACTT may represent the next step for the search of best surgical treatment for PCG.
