简要总结
The objective of this prospective randomised study is to compare the efficacy and safety of ologen CM (Collagen matrix) as adjunct to combined trabeculotomy-trabecuectomy in congenital glaucoma cases, the efficacy being the primary objective and the safety being the secondary. The investigators hypothesize that combined trabeculotomy-trabecuectomy with Ologen collagen matrix implant implantation in congenital glaucoma is a safer procedure and may yield better results than combined trabeculotomy-trabeculectomy approach.
详细描述
"Ologen ® CM" is a biodegradable collagen matrix. To prevent episcleral fibrosis and subconjunctival scarring thay may result in the surgical failure in filtration surgery, its sporous matrix modulates the migrations and proliferations of fibroblasts to create a vascular and long-lasting bleb without the adverse effects.
Results of ologen CM studies have been published at conferences and published in peer-reviewed journals; ologen CM is approved in Europe as an aid for tissue repair, and by the FDA in the US as an adjunct in wound management(K080868). In general, over 7,000 ologen CM have been implanted worldwide during the past two years with good results and excellent safety profile.

结局指标
主要结局
Intraocular pressure(IOP) reduction
时间窗: At postoperative up to 24 months
"Complete success" is consider for IOP less than 21mmHg(inclusive) with no glaucoma medications and with more than 20% reduction(inclusive) from baseline IOP. Definition of success rate is calculated in percentage by the number of complete success patients over the total sample size. "Qualified success" that meets the postoperative IOP requirements with postoperative glaucoma medicaitons and "Failure" of meeting the IOP requirements are the other efficacy parameters. In the specified time frame, patients will also visit for record at day 7, 30, 90, 180 days, 12, 18, and 24 months.
次要结局
- Postoperative complications and appearances.(At postoperative up to 24 months.)
