In the elderly population, glaucoma is the primary cause of blindness. Glaucoma causes blindness by destroying optic nerve fibers (which send visual information from the eye to the brain).
The cause of glaucoma is unknown.
The healthy equilibrium between aqueous humor production and drainage is responsible for the eye’s internal pressure, or intraocular pressure.
Impaired outflow of aqueous due to anomalies within the drainage system of the anterior chamber angle or impaired access of aqueous to the drainage system is the mechanism by which glaucoma raises intraocular pressure.
The intraocular pressure is set by the balance between the eye’s aqueous production and its outflow. Because of a disruption in this equilibrium, fluid does not drain from the eye at the same rate at which it is produced, leading to a buildup of pressure and glaucomatous damage.
The optic nerves of the retina are damaged by the increased pressure, resulting in impaired vision.
Damage to a sufficient number of nerve fibers leads to the formation of blind patches in the field of vision. When a whole nerve fiber is severed, it might cause permanent blindness.
Thus, the prevention of optic nerve fiber loss and blindness from the condition depends on its early identification and treatment by the Best Ophthalmology expert.
Primary and secondary glaucoma are distinguished by whether or not additional risk factors for eye pressure increase are present.
Glaucoma is divided into open-angle and closed-angle subtypes based on the intraocular pressure mechanism involved.
Open-angle glaucoma, sometimes know as “the thief of sight,” is a frequent form of the eye disease. Here, the aqueous drainage system gradually loses its effectiveness, mostly as a consequence of becoming older, causing intraocular pressure to rise.
Chronic open-angle glaucoma occurs when this elevated pressure causes damage to the optic nerve.
One common nickname for glaucoma is “the thief of sight” because of this. You won’t even notice that your eyesight is deteriorating since it happens so slowly and painlessly.
People between the ages of 40 and 70 should have annual eye exams, since the condition may not present any symptoms at first. In the event of severe eye issues, prompt medical attention is required.
