Abstract:
Non perforating trabecular surgery (NPTS) with reticulated hyaluronic acid implant (Skgel) allows aqueous humor to leave anterior chamber through a thin trabeculo-Descemet's membrane into a sclerocorneal space filled with Skgel implant and then via the outflow physiological channels. Good IOP results are obtained with less or without external filtration decreasing the incidence of per- and postoperative complications described after trabeculectomy. This surgery is actually only indicated for primary open angle glaucoma, the trabeculectomy still remaining the gold standard procedure for the other glaucoma cases.
