To report a presumed cause for the transient visual loss noted by a patient wi th a leaking bleb following trabeculectomy. Case report. Description of an other wise healthy woman who developed delayed onset transient visual loss associated with a leaking filtering bleb. A 62 year old woman who underwent trabeculecto my with mitomycin C in her right eye 5 years earlier (Feb 23, 1999) presented with a 3 month history of transi ent decreased vision. The apparent cause was a periodic gush of aqueous flowing across the surface of the cornea. One cause of bleb associated transient visual loss can be aqueous leaking from the bleb on to the anterior surface of the cor nea, disturbing vision as it flows past the visual axis. This is temporarily rel ieved by blinking.
