**10. Solx gold microshunt (GMS)**

The GMS is a flat-plate non valved drainage device which is inserted in the suprachoroidal space and increases uveoscleral outflow. It is made of 24 karat gold and its dimensions are 3.2 mm wide, 5.2 mm long and 44µm thick. The aqueous enters the device from the proximal side which contains 60 holes 100 µm each. The device contains 10 open and 9 closed channels (width of lumen 24µm and height 50µm) and at the distal end the fluid exits in the suprachoroidal space via a grid of 117 holes on either side. The proximal end of the GMS contains 12 additional channels and the distal end 10 channels 50 µm each

Ting et al [110] reported that Trabektome controls IOP better in eyes with pseudoexfoliation glaucoma than primary open angle glaucoma and has more profound effect when combined

The Aquashunt device is placed in the suprachoroidal space and aims to facilitate aqueous outflow via the uveoscleral pathway. Instead a multiple small channels it has one large
