Resumen breve

To compare the surgical outcomes of treating phacoemulsification with intraocular lens implantation combined with goniosynechialysis (Phaco-IOL-GSL) associated malignant glaucoma (MG), using different incision sites in anterior vitrectomy combined with hyaloidotomy, zonulectomy, and iridectomy (VHZI).

Nombre de intervención: anterior vitrectomy combined with hyaloidotomy, zonulectomy and iridectomy

Descripción: First, a 23-G incision was made at the peripheral inferior temporal sector of the cornea and connected with an anterior chamber infusion cannula. Another corneal incision was made at the superior temporal sector or superior nasal sector, and Viscoat® (Bausch & Lomb, Shandong, China) was infused though the incision to fill the anterior chamber. Iridotomy was performed through the incision using Wescott scissors and toothed forceps. Hyaloidectomy and zonulectomy were performed through a peripheral iris defect using an anterior chamber approach to set up a pathway between the anterior chamber and the vitreous cavity. We repeatedly carried out vitrectomy around the pathway to reduce the risk of postoperative re-obstruction of the tunnel created.
