The first thing you need to know about how to deal with atrial aqueous blockage is the circulatory pathway of atrial aqueous, a cross-sectional view of the eye. When the atrial fluid is secreted by the non-pigmented epithelial cells of the ciliary body, the atrial fluid has to flow through the pupil area to the anterior chamber. The anterior chamber is the space with the cornea, iris, and lens surface, and the angle between the iris and the cornea is the atrial angle. When the atrial horn is mechanically closed or when it is open but blocked or not functioning well, the atrial water in the eye does not flow outside the eye, resulting in blockage of the atrial water. When the atrial horn appears to be closed, it is important to find a way to release the atrial horn from closure, such as laser perforation of the iris or surgery, which can open the atrial horn. What to do when the atrial horn is open but somewhat blocked? You can lower the IOP by partially medicating the atrial horn to allow for increased external drainage of the atrial fluid. If drugs and laser do not achieve better results, the atrial fluid is still blocked and the IOP is still high, how to deal with it, only surgery can be done, that is, external drainage surgery, the opening on the eye for the so-called external drainage, the procedure is called the surgical way of glaucoma. This procedure is called glaucoma surgery. It allows water to flow out of the eye through an open channel, thus lowering the eye pressure and relieving the problem of atrial fluid blockage. So medication, laser or surgery are all possible.
