To the best of Investigator knowledge, no studies to this date have compared the safety and efficacyof ologen® Collagen Matrix to MMC in exaggerated healing response among JOAG patients. Given that,filtration surgery is usually less successful in patients with juvenile glaucoma; the purpose of this study is to compare these two adjuvant therapies in exaggerated healing response among JOAG patients. Investigator hypothesis is that trabeculectomy with ologen® Collagen Matrix would be as effective as MMC in IOP control, with prominent bleb morphology as compared to MMC bleb.
Standard trabeculectomy All trabeculectomy surgeries will be performed under peribulbar anesthesia.Under aseptic surgical technique, superior rectus suture will be placed using 4-0 silk and a fornix-based conjunctival flap will be performed. Sub-Tenon dissection and hemostasis may be performed as required.A half-thickness 4 x 4mm rectangular/ triangular scleral flap will be dissected up to clear cornea, and a 2 × 2 mm deep scleral block will be excised and peripheral iridectomy will be performed. The scleral flap will be closed with one or two 10-0 nylon sutures and conjunctiva will be closed with 8-0 vicryl suture. Releasable sutures may be applied to the scleral flap if needed.
