The Micro-invasive glaucoma surgery(MIGS)group of operations has been developed in the recent years to reduce some of complications of most standard glaucoma procedures such as trabculectomy. In order to increase the surgical effect, a new group of surgical manners has emerged that seeks to decrease IOP with lower associated rates of complications. The MIGS of the latest technique and devices are presented by three manners of reducing IOP: aqueous reduction surgery(Endoscopic Cyclophotocoagulation, Ultrasound Cyclo-Plasty); external filtering surgery(Implantation of EX-PRESS miniature glaucoma device, CANALOPLASTY); internal filtering surgery(Trabecular microbypass stent, Ab Interno Trabeculectomy). The article will summarize clinically relevant information of the glaucoma treatment and to describe indications, advantages and disadvantages of the MIGS.
