Glaucoma is the 2nd leading cause of blindness after cataract. However, if we consider irreversible blindness glaucoma is the leading cause.Glaucoma Can Lead To Permanent Loss Of Vision.
In India alone, glaucoma affects 12 million people and by 2020, this is expected to reach 16 million. Nearly more than 90% of these cases are undiagnosed.Glaucoma causes progressive sight loss and, unlike cataract is irreversible.
Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. The most common type is open-angle glaucoma with less common types including closed-angle glaucoma and normal-tension glaucoma.
In the eyes a fluid is produced and constantly drained out. It is drained through a structure situated at an angle between the cornea and the iris. When the drainage mechanism becomes ineffective, the pressure in the eye increases causing optic nerve damage.
Glaucoma is treatable only when it is detected in the early stage. The damage caused by it is irreversible. The Glaucoma Treatment includes medicines,laser treatment or surgery.The medicines are prescribed either to increase the drainage of the fluid or decrease the fluid production to keep the eye pressure under control. In certain cases you might need lifelong treatment.Lasers are used in the Glaucoma Treatment to increase the flow of fluid.When both treatments fail, you may have to undergoa surgery.
