Glaucoma is a type of disease that causes weakening and damaging of eye’s optic nerve, and with increase in pressure inside the eye, it can also result in loss of vision and ultimately blindness. Since the function of the optic nerve is to relay the images seen to the brain, its ability to convey that important piece of information is seriously hampered when it gets damaged, and the brain is no longer able to interpret the imagery seen by the person’s eye.
The worst thing about this ailment is that it does not show any signs in its early stages, and the symptoms only occur when the damage to the optic nerve crosses an alarming 70%. In cases where eye pressure is not controlled with medication or is at an advanced level, such cases have to undergo a surgery called “trabeculectomy” to enhance fluid drainage and preserve the eye pressure at a standard level. If the trabeculectomy surgery fails to manage the eye pressure, other procedures like “glaucoma drainage device implantation”, “cyclocryotherapy”; may be required to address the ailment.
