Causes and symptoms of glaucoma
1. What is Glaucoma?
The normal eye has the shape of a sphere, about 2 cm in diameter, containing a type of water, called aqueous humor, which circulates regularly to nourish many parts of the eye. The circulation of aqueous humor is always in equilibrium. This fluid must exit the eye, through the small openings in the front, into the body. If these holes are narrowed or blocked, the fluid will pool, causing increased pressure in the eye (glaucoma), damage to the optic nerve, leading to blindness.
Glaucoma is quite common and has no symptoms in its early stages, so it is difficult to recognize. However, if detected early and the right treatment can stop the progression of the disease, patients can avoid serious vision and field of vision loss.
2. Who is susceptible to glaucoma?
Diseases with genetic factors. In a family with glaucoma, those of the same blood have a 5-6 times higher risk of developing the disease.
Glaucoma has no signs of infection, and in elderly patients, it is easy to confuse it with presbyopia. Therefore, the disease is often detected late, when patients come to the doctor when their eyes are completely blurred, it is too late because of irreversible optic nerve damage.
