What is seamless glaucoma surgery (GATT)?
There is an enormously balanced system that pumps fluid into our eyes and drains excess fluid out. You can think of it as a kind of circulation. Thanks to this system, our eye pressure is kept between certain values. However, if there is a blockage in this evacuation mechanism, since the produced fluid cannot go out, the eye pressure increases and the disease we call glaucoma occurs. Increased intraocular pressure causes permanent damage and thinning of the optic nerve, which transmits light impulses behind the eye to the brain. Glaucoma is a very insidious disease. It starts to narrow the visual field from the outer side first and keeps the central (central) in the last stage, so the patient is blind in the last stage without being aware of the vision loss.
consults his doctor. In treatment, glaucoma drugs that decrease production and increase excretion are given first. If these are insufficient, surgery is necessary. In the past, an operation was performed by cutting the white of the eye (sclera) and stitching it. Of course, the risks and complications of this surgery were quite high. In GATT surgery, the eye is entered through very small holes that close spontaneously without cutting the outer layers of the eye, and the occluded areas are opened again. It is a safe operation without sutures, with a very low risk of complications and a high chance of success.
