The 7th to 13th of March 2021 will be designated as World Glaucoma Week. This year’s theme represents the hope that frequent testing will enable people to see the world around them as it is: full of elegance, charm, and adventure. The world is bright; protect your eyes!
Glaucoma, also known as Kala-Motia, is a form of eye disease that is one of the most common causes of blindness. Adults over the age of 35 are particularly prone to it. Glaucoma-related blindness will almost always be avoided if detected early. It is a disorder that affects more than 60 million people worldwide. Worse still, more than half of them are unaware of it before it is too late.
Glaucoma affects the optic nerve, which is responsible for transmitting visual information to the brain. A fluid provides nutrients to the eye, and the pressure of this fluid stays controlled in normal eyes. The channels carrying the fluid become blocked with age, illness, trauma, or other causes, raising the pressure inside the eye.
“In most cases, there are no signs of this increased pressure,” says Dr Vineet Sehgal, Senior Glaucoma Consultant at Sharp Sight Eye Hospitals. The disease functions invisibly, causing damage to the outer or peripheral vision first, while the central vision is preserved. The patient has already sustained permanent peripheral vision loss by the time the problem is discovered.”
Glaucoma Is Divided Into Several Types
Chronic glaucoma or primary open angle glaucoma: This is the most common form of cancer. This form of glaucoma causes progressive vision loss that is usually painless.
Closed Angle or Acute Glaucoma: The intraocular pressure rises rapidly due to a sudden and extreme blockage of fluid drainage inside the eye in this form of glaucoma. The presence of acute glaucoma is immediately indicated by significant symptoms. Otherwise, blindness could result if this condition is not treated promptly by an ophthalmologist.
Regular eye exams can help detect glaucoma early on, reducing the likelihood of vision loss. As a result, everyone in the high-risk community should get screened. “People with a family background are at greatest risk and should have an annual test performed, regardless of their age,” said Dr. Vineet Sehgal. Diabetics, hypertensive patients, and thyroid patients are among those that fall into this group.
