What is glaucoma?
Glucose is an eye disease in which the optic nerve is damaged by factors such as increased intraocular pressure (or short-term pressure of the eye). Because the vision nerve is responsible for transmitting vision information to the brain, damage to the visual field defects and ultimately leads to complete blindness if the disease is not treated and progressed.
The cause of glaucoma
In some cases, the cause of glaucoma is detectable, such as eye injury, eye surgery, and angle closure, but in many cases glaucoma is an unknown cause, and genetic and environmental factors are involved.
Types of glaucoma
The glaucoma can be divided into two groups, an open angle and a closed angle. It is good that you also know that the angle of the eye is part of the eye that is between the iris (the color part of the eye) and the cornea (the transparent part of the eye). Typically, the fluid in the eye is produced in the front area of the eye; this fluid is produced in the eye and is removed from the eye area. If the angle of the eye is damaged or closed, this liquid is not able to exit the eye and it causes an increase in intraocular pressure and the occurrence of glaucoma.
In most cases, patients with glaucoma are open-angle, but in a number of patients, they also have stenosis or closure of the eye.
The symptoms of glaucoma
A. Congenital glaucoma with symptoms such as white cornea, tearing, and fear of light and large eyes.
B: Open angle glaucoma: In most cases, open angle glaucoma (as well as closed angle glaucoma) is chronic, the patient will not notice glaucoma unless the disease progresses and visual disturbances are caused.
C: Acute Close Angular Glaucoma: This disease with acute symptoms reduces eye sight, tears, fear of light, seeing the halo and rainbow around the lights, nausea and vomiting. In such circumstances, the patient should be referred to the ophthalmologist as an emergency and be treated promptly.
In most cases, full-scale clinical examinations, including intraocular pressure measurements, eye examinations, visual acuity examination, and visual field testing are enough to detect glaucoma; however, in some cases, other tests, such as imaging of the optic nerve and the retina, are also required. There is.
Is glaucoma treatable?
In the process of glaucoma, the vision nerve is gradually damaged and the nerve cells in it are gradually dying. When glaucoma is detected, there is no cure for part of the nerve fibers that is lost. The main goal of the treatment of glaucoma is to prevent the progression of the disease and preserve the remaining vision for the normal life of the patient.
