Glaucoma is a chronic disease that we must evaluate, evolve in time, and treat. Treatment prevents further loss of optic nerve fibers. In advanced glaucoma, these premises must be fulfilled, but with no margin of error due to the significant damage to the nerve. Diagnostic and evolutionary studies have their characteristics due to the presence of few nerve fibers. We will use the same studies but focused on studying the central vision. And, of course, the treatment must be more aggressive to comply with the premise that the damage does not increase. It is more demanding because of the need for constant low intraocular pressures (IOPs). Several failures in the management of glaucoma at the social level mean that this disease still blinds people. Controls such as treatment are essential to prevent further nerve damage and blindness.
