Cyclodialysis cleft formation during canaloplasty with itrack 250a microcatheter.Cleft repair was carried on the same day as a precaution to prevent hypotony.An mvr blade was used to make the goniotomy.During initial intubation of the schlemms canal with the microcatheter an obstruction was encountered within 1 clock hour of the goniotomy.The surgeon applied additional pressure to the microcatheter with microforceps, the obstruction could not be by-passed, however this resulted in a kink in the microcatheter and a 1 clock hour cyclodialysis cleft.Subsequently an attempt was made to intubate schlemms canal with the same microcatheter from the opposite direction.The microcatheter went into the cyclodialysis cleft and not schlemms canal.The surgeon then abandoned the canaloplasty, performed a cataract removal and repaired the cleft.The surgeon noted that the mvr blade could have caused a deeper opening in the wall of the schlemms canal, leading to increased likelihood of cleft formation.
