The Influence of Scleral Flap Thickness, Shape, and Sutures on Intraocular Pressure (IOP) and Aqueous Humor Flow Direction in a Trabeculectomy Model.
PURPOSE Intraocular pressure 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. METHODS The model exp...
متن کاملA Review of Scleral Flap Shape on Trabeculectomy Outcomes
Introduction: Trabeculectomies are amongst the most common surgical procedures to lower intraocular pressure (IOP). Scleral flap dimensions are a key factor in influencing aqueous outflow and subsequent IOP reduction, especially in the early postoperative period. Despite the substantial diversity of scleral flap shapes that is used in practice, there is little information comparing outcomes bet...
متن کاملTrabeculectomy augmented with mitomycin C application under the scleral flap.
AIM The authors investigated the safety and intraocular pressure (IOP) lowering effectiveness of trabeculectomy augmented with mitomycin C application beneath the scleral flap, and assessed the influence of preoperative risk factors on the surgical outcome. METHODS A retrospective study of 72 consecutive high risk eyes undergoing trabeculectomy with adjunctive mitomycin C (0.2 mg/ml) applied ...
متن کاملChange in intraocular pressure during scleral depression.
PURPOSE Manometric studies have found that intraocular pressure (IOP) rises 116-350 mmHg during scleral depression in surgical settings. No information is available regarding the effect of scleral depression on IOP in routine clinical settings. The aim of this study is to quantify the change in IOP that occurs when scleral depression is performed on normal eyes in a routine clinical setting. ...
متن کاملMedium to long-term intraocular pressure control following small flap trabeculectomy (microtrabeculectomy) in relatively low risk eyes.
AIM To determine the long-term efficacy of small flap trabeculectomy (microtrabeculectomy) in terms of intraocular pressure (IOP) control in relatively low risk eyes. METHOD A review of a case series of small flap trabeculectomy procedures performed on 36 eyes from 36 patients with a minimum follow up of 24 months (mean 50.8). RESULTS The mean (SD) intraocular pressures at presentation and ...
