Glaucoma is called the sight-stealing disease, and the name rightly defines its severity. Millions of people lose their vision every year around the world.
Since there are no prominent symptoms of it, the regular checkup is the only way to detect the ailment.
Experts say that this ‘sneak thief of sight’ can be caught red-handed and arrested if it is diagnosed timely.
However, most of the people have already lost almost half of the vision without even noticing by the time they are diagnosed and treated.
With the increasing population of older adults in India, there is a risk of having a rampant of blindness impending if Glaucoma is not controlled.
According to eye-specialists, it is possible to control the disease if people know about it in detail.
The information about the causes, symptoms and diagnostic tests must be spread amongst the society. The more people know about it, the lesser is the impact.
What is Glaucoma?
It is a group of vision ailments that steal the sight without any warning signs. Though it is considered a disease of older adults, Glaucoma may hit at any age.
The loss of vision happens due to the damage in the optic nerve that is like an electric cable with more than a million wires. Through this intricate network, the image is carried to the brain.
Once damaged, the nerves can’t be repaired. Therefore, the loss is permanent. There is no cure for it, medication or surgery can reduce the speed of the damage.
Types of Glaucoma
Glaucoma is classified into two types; POAG or Primary open-angle Glaucoma and ACG or Angle-closure glaucoma.
There is an increase of intraocular pressure or IOP or pressure inside the eye. Due to Intraocular pressure, the optic nerve gets damaged.
In some cases, the nerve gets damaged despite normal Intraocular pressure. It is known as Normal Tension Glaucoma.
Secondary Glaucoma is a case where some other ailment causes an increase in eye pressure, e.g., Hypertension or Diabetes. It results in vision loss due to the damage caused to the optic nerve.
When a patient is diagnosed for Glaucoma, doctors try to restore the normal eye pressure as fast as possible.
It stops the optic nerve from getting damaged further. Thus, the loss of vision ends. However, the damage that has already happened can’t be restored.
What is essential to prevent Glaucoma?
Regular checkup after the age of 40 can reduce the risk of Glaucoma up to a large extent.
People who have high blood pressure, or a family history of Glaucoma are under a high risk. They must get the checkup done every year.
It helps in finding out the problem in the early stage. Vision loss can be avoided by acting early.
