GATT: Gonioscopy Assisted Transluminal Trabeculotomy

There is a worldwide need for an efficient, cost-effective, bleb-less glaucoma procedure that safely and successfully lowers intraocular pressure while improving outflow through the natural outflow channels. As the enthusiasm for GATT grows, we are grateful to each of the authors of this book for graciously sharing their collective wisdom with the international audience to continue to foster global education and collaboration, specifically in terms of ab interno circumferential trabeculectomy.

Each contributor to this book represents an international lighthouse, or GATT-beacon, that serves as a guide to surgically reduce the global burden of blindness from glaucoma. It is only through thoughtful, synergistic global collaboration that we can work to improve surgical glaucoma care and continue to innovate. GATT is just another step in the continuum of innovative, cost-effective angle surgery; we hope this book serves as inspiration for future generations of ophthalmologists to improve canal-based surgery on a global basis.
