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.
