The influence of scleral flap thickness shape and sutures on intraocular pressure (IOP) and aqueous humor flow direction in a trabeculectomy model

摘要

PurposeIOP and aqueous humor flow direction determined by the scleral flap immediately after trabeculectomy are critical determinants of the surgical outcome. We used a large-scale model to objectively measure the influence of flap thickness and shape, and suture number and position on pressure difference across the flap and flow of fluid underneath it.
