Glaucoma Treatment In GhatkoparGlaucoma is Cluster of eye diseases, resulting in optic nerve damage. Main function of optic nerve is to carry images from the retina, which is the specialized light sensing tissue, to the brain for interpretation so we can visualize it. In many cases, we do not know exactly what causes glaucoma. However, increased eye pressure is the most common risk factor for developing the disease. The pressure comes when the clear fluid in the eye, called the aqueous humor, does not drain properly.
This fluid normally helps to nourish the eye, and flows in and out of the eye through a mesh-like channel. In people with high eye pressure, the fluid does not drain properly and pressure builds up in the eye.
Due to this eye pressure delicate nerve fibers of the optic nerve are damaged. Once these nerve fibers are damaged, blind spots develop in the field of vision. It’s a permanent loss, once nerve damage and visual loss occur. Most people don't notice these blind areas until much of the optic nerve damage has already occurred. Glaucoma is a leading cause of blindness in the world, especially in older people.
What are symptoms of Glaucoma?
Open-angle glaucoma is asymptomatic. It develops slowly and sometimes without noticeable sight loss for many years. Most people who have open-angle glaucoma feel fine because the initial loss of vision is of side or peripheral vision, and the visual acuity or sharpness of vision is maintained.
As open-angle glaucoma has few warning signs or symptoms before damage has occurred, it is recommended to see a doctor for regular eye examinations. In open-angle glaucoma, the angles in your eye are normal, but the eye’s drainage canals become clogged over time, causing an increase in internal eye pressure and subsequent damage to the optic nerve.
In Angle-closure glaucoma (also called narrow angle glaucoma) the angle is closed, causing increased eye pressure, which leads to optic nerve damage, and possible vision loss. There is an acute attack of angle closure leading to noticeable symptoms and damage occurs quickly. If you experience any of these symptoms, seek immediate care from an ophthalmologist.
Hazy or blurred vision
The appearance of rainbow-colored circles around bright lights
Severe eye and head pain
Sudden vision loss
Nausea or vomiting (accompanying severe eye pain)
Congenital glaucoma is glaucoma occurring in children, whether from birth or at a very early age. This usually happens from a physical defect in the eye that doesn’t allow it to function normally, but it can also come from some other medical issue.
Pigmentary glaucoma, or pigment dispersion, blocks the drain of your eye with tiny granules of the eye’s pigment, or the iris, after circulating through the fluid at the front of your eye.
Secondary glaucoma – Glaucoma with associated conditions like tumor, diabetes, an advanced cataract, or inflammation.
