Vascular changes over trabeculectomy blebs.
Low-dose anterior segment fluorescein angiography was performed on 10 eyes before and after trabeculectomy with a limbal-based conjunctival flap. Post-trabeculectomy angiography shows that all successful trabeculectomies have an area of decreased capillary vascular perfusion over the bleb site not coincidental with the area of the bleb and that there is delayed filling of vessels running over the bleb.
