NCT01124578
PURPOSE OF EVALUATION: This study will verify \& validate the acceptability of Egret's extended use product as compared to the existing daily change-out product. Based on an extensive in-vitro study, Egret's product confirmed significant kill for both positive and negative gram bacteria. In addition to meeting all of the current product requirements, total aerobic bio-burden on the catheters will be tested at various intervals for up to 10 days of use. The current used product will be used as a control group that is to be changed out daily as per current policy. The control group will be tested for total aerobic bacteria counts on the last day of use.
NCT00607685
Trabeculectomy is the most effective method of lowering intraocular pressure in glaucoma that is not well controlled with drop medication. The post-operative wound healing response remains the major barrier in surgical success. Scar tissue formation results in occlusion of the surgical drainage site created. As a consequence, the intraocular pressure rises once again. The current use of anti-scarring agents such as 5 Fluorouracil (5FU), is a well established method employed by ophthalmologists to clinically reduce the postoperative scarring response. However, in patients with a high risk of bleb failure, repeated subconjunctival injections of 5FU following bleb needling is often required resulting in increased clinical load and patient inconvenience. A slow release formulation of 5FU would be of benefit by releasing the 5FU into the subconjunctival space over an extended period thereby providing a prolonged therapeutic effect. In addition, hyaluronic acid is known to possess antifibrotic properties and from its gel-like physical state, would potentially act as a physical tissue spacer that may further limit active subconjunctival scarring at the site where it is injected. We hypothesise that injecting a mixture of 5FU with hyaluronic acid would give better outcomes than injecting 5FU alone. The aim of this study is to determine whether bleb needling with subconjunctival injection of Viscoelastic/5FU formulation is an effective method for prolonged drug delivery in preventing the post-operative scarring response. This will be a prospective case-controlled study involving patients who have already undergone trabeculectomy and who require bleb needling and subconjunctival 5FU injections.
