Glaucoma is the second leading cause of blindness in the world accounting for up to 8% of total blindness. In India, glaucoma is the leading cause of irreversible blindness with at least 12 million people affected and nearly 1.2 million blind people from the disease. More than 90 percent of cases of glaucoma remain undiagnosed in the community.
What is Glaucoma?
Glaucoma is a term used to describe a group of
diseases of the eye characterized by progressive and irreversible damage
to the optic nerve (nerve of the eye responsible for vision) and which
if untreated can lead to blindness. Though raised pressure of the eye is an important risk factor, a
few individuals can develop glaucoma even with normal pressure of the
Why is Glaucoma A Silent Thief of Vision
Glaucoma is also called the silent thief of sight because in the early stages of the disease, there may be no symptoms. By the time glaucoma is detected, the patient has already suffered extensive peripheral vision damage which can no longer be restored. The statistics reveal that by the time people realize that something is amiss and consult a doctor for glaucoma treatment, 90% of them have lost half of their vision. It comes so slowly that it goes unnoticed in most of the people.
How do we prevent vision loss due to glaucoma
Regular eye examination is the key to help detect this disease
in early stages and preserve healthy vision. Since most people with glaucoma have no early symptoms or pain, it is important to see your eye doctor regularly so that it can be diagnosed early and glaucoma
treatment can be done and an irreversible sight loss can be prevented.
Who is at risk for glaucoma
Risk for glaucoma increases with
- age over 40 years
- family history of glaucoma
- steroid use
- trauma to eye
- -high myopia as well as hypermetropia
- medical conditions, including diabetes
What are the types of Glaucoma
Glaucoma can be classified into four basic types based on the event initiating damage. They include
- Primary open-angle glaucoma
- Primary angle-closure glaucoma
- Developmental glaucoma (which affects children)
- Secondary glaucoma (which occurs due to other disorders of the eye or the body )
How glaucoma affects vision
A fluid known as aqueous nourishes the front part of the eye. In the normal eye, the rate of production of aqueous matches the rate of its drainage, thereby maintaining optimal pressure inside the eye. The blockage of meshwork like channels carrying this fluid increases the pressure inside the eye. This increased pressure damages the optic nerve, which is the conduit of visual messages to the brain. Working silently, glaucoma damages the outer or peripheral vision first while maintaining the central vision and if not treated on time it may lead to loss of central vision and blindness.. Worldwide, it is the leading cause of irreversible blindness.
How can glaucoma be treated
Once detected, glaucoma can be controlled by medicines (eye drops) or surgery to prevent further vision loss. This can only be done through disciplined and regular glaucoma treatment from an eye specialist. Treatment of Glaucoma is lifelong. Glaucoma treatment may include medical management, surgical management or management by lasers.At JAI EYE CENTRE with our team of specialists and advanced state-of-the-art equipment we are fully geared not only to detect early stages of Glaucoma but also its treatment and surgical management.
