NCT03541551

Brief Summary

To the best of Investigator knowledge, no studies to this date have compared the safety and efficacy of ologen® Collagen Matrix in Primary congenital glaucoma (PCG) patients undergoing trabeculectomy. Given that filtration surgery is usually less successful in patients with developmental glaucoma; the purpose of this study is to compare combined trabeculectomy with trabeculotomy (CTT) with adjuvant ologen® Collagen Matrix versus CTT without ologen® in children with PCG. Investigator hypothesis is that CTT with ologen® Collagen Matrix would be as effective as CTT in IOP control, but with reduced scarring and long term healthier bleb morphology.

Outcome Measures

Primary Outcomes (1)

  • Comparing IOP control between the two groups:Change of intraocular pressure (IOP) over time

    Assess control of IOP over time. "Complete success" is defined as IOP reduction of \>20% and / or an IOP constantly \<21 mmHg without any antiglaucoma medication. "Qualified success" is defined as IOP \< 21 mmHg with topical antiglaucoma medication. "Failure" is defined as IOP \> 21mmHg in 2 subsequent follow visits despite topical antiglaucoma medication.

    12 months

Secondary Outcomes (1)

  • Comparing bleb morphology in two groups by change of Moorfields Bleb Grading System (MBGS) score over time

    12 months

Masking Details
Eligible patient after screening will be assigned consecutive randomization numbers in ascending order upon enrollment. The patient will be randomized in 1:1ratio to one of two study groups, namely combined trabeculotomy with trabeculectomy with ologen® Collagen Matrix as adjunctive wound modulator(Group A) or combined trabeculotomy with trabeculectomy alone without any adjunctive (Group B). The assigned randomization number will be recorded in each subject's DCF. The randomization scheme will be generated using random function in excel before patient enrollment in order to avoid investigator's patient selection bias.
