A medida que este nervio se deteriora gradualmente, aparecen puntos ciegos en el campo visual. El glaucoma suele ser hereditario. Nadie conoce el motivo exacto de esta enfermedad. Open-angle glaucoma is the most common form of the disease.

The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked. This causes pressure in the eye to gradually increase. This pressure damages the optic nerve. It happens so slowly that you may lose vision before you’re even aware of a problem.

Angle-closure glaucoma, also called closed-angle glaucoma, occurs when the iris bulges acuso to narrow or block the drainage angle formed by the cornea and iris.

As a result, fluid can’t circulate through the eye and pressure increases. Some people have narrow drainage angles, putting them at increased risk of angle-closure glaucoma. Angle-closure xcuoso may occur suddenly acute angle-closure glaucoma or gradually chronic angle-closure glaucoma.

Acute angle-closure glaucoma is a medical emergency. In normal-tension glaucoma, your optic nerve becomes damaged even though your eye pressure is within the normal range.

No one knows the exact reason for this. You may have a sensitive optic nerve, or you may have less blood being supplied to your optic nerve. This limited blood flow could be caused by atherosclerosis — the buildup of fatty deposits plaque in the arteries — or other conditions that impair circulation.

It’s possible for infants axuoso children to have glaucoma. It may be present from birth or develop in the first few years of life. The optic nerve damage may be caused by drainage blockages or an acuoao medical condition.

In pigmentary glaucoma, pigment granules from your iris build up in the drainage channels, slowing or blocking fluid exiting your eye.

Activities such as jogging sometimes stir up the pigment granules, depositing them on the trabecular meshwork and causing intermittent pressure elevations. Es posible que no puedas prevenir el glaucoma. Solicite una Consulta en Mayo Clinic.
