More studies comparing placement sites of tube shunts needed

Trabeculectomy and tube shunt implantation are the most frequently performed incisional surgeries for the management of glaucoma. Historically, trabeculectomy was the preferred procedure and tube shunt implantation was reserved for refractory glaucoma at high risk for filtration failure. Over the last two decades, however, there has been a decline in the number of trabeculectomies performed with an increase in tube shunt implantation. Furthermore, the recent publication of the 5-year follow-up of the Tube Versus Trabeculectomy Study solidified the role of tube shunt surgery by suggesting that tube shunt surgery may have an advantage over trabeculectomy.Anterior chamber placement
