Glaucoma is a leading cause of worldwide blindness. Treatment of this chronic disease, centered on lowering intraocular pressure (IOP), may require surgical intervention when medical and/or laser therapy fail to control IOP. Traditional glaucoma surgery, such as trabeculectomy, has been performed for decades and has a proven track record of success. Unfortunately, many complications such as hypotony and slow visual recovery are known to occur and can lead to significant patient morbidity. New devices are being developed to allow surgeons increased control with more predictable postoperative results. One such device, the Ex-PRESS mini glaucoma shunt, has undergone changes in design and method of insertion making it more appealing for use in patients requiring IOP-lowering surgery. We summarize pertinent literature and expand on the future role of this device in glaucoma surgery.
