title: Incising the thick retrolental fibrovascular tissue with a hooked sclerotome in persistent hyperplastic primary vitreous.
abstract: A technique for incising thick retrolental fibrovascular tissue and extensive cyclitic membrane is reported in a case of anterior persistent hyperplastic primary vitreous. A membranectomy was performed in a 1-month-old post-lensectomy baby via a limbal approach. A sclerotome tip was hooked to cut through an extremely thick fibrovascular tissue by rotating the sclerotome by its grip. Sutherland microscissors (Grieshaber, Switzerland) and a vitrectomy cutter were used for further membranectomy. The baby was followed-up until age 18 months. A total of 3 membranectomy sessions were required because of rapid cyclitic membrane formation, severe centripetal retraction of the membrane on the ciliary processes, and posterior synechia. Thorough membranectomy and cutting the iris edge maintained a clear pupillary area during the 13-month postoperative period. Extremely thick retrolental fibrovascular tissue is a challenging condition that can be dealt with by delicate instrumentation.
