NCT02121171

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Intraocular pressure(IOP) reduction

    "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.

    At postoperative up to 24 months

Secondary Outcomes (1)

  • Postoperative complications and appearances.

    At postoperative up to 24 months.

Study Arms (2)

Ologen Collagen Matrix Intervention

EXPERIMENTAL

Combined trabeculotomy-trabeculectomy with subconjuncitval Ologen matrix implant implantation is a new procedure that has less post operative complications with good results, it is to be applied in children.

Device: Ologen Collagen Matrix

Combined trabeculotomy-trabeculectomy

ACTIVE COMPARATOR

Combined trabeculotomy and trabeculectomy is a standard surgery for congenital glaucoma, however, it has its known complications.

Procedure: Combined trabeculotomy-trabeculectomy

Interventions

Use of ologen Collagen Matrix in trabeculectomy (ologen) Place ologen CM on the top of the loosely-sutured scleral flap under conjunctiva before suturing. It is recommended to suture the scleral flap with 1 or 2 stiches loosely and to coordinate with the tamponading effect of ologen CM to create a fluctuating scleral flap that prevents bleb wound adhesion and modulates aqueous humor outflow for ideal IOP control without leakage.
