Glaucoma, its causes, and its symptoms

A very common eye problem that eye doctors in Phoenix AZ treat is Glaucoma. It is a condition that can affect sight mainly due to the buildup of pressure within the eye. It is a leading cause of blindness in the world, generally among elderly. The early detection and treatment by an expert eye doctor is highly recommended to prevent optic nerve damage and vision loss from this eye disease.

Main causes of glaucoma

In the eye, the aqueous humor is produced at a constant rate by the ciliary body which circulates through the anterior chamber and then flows out of the eye at the same rate through the drainage angle. This balanced state of aqueous humor keeps the pressure in the eye constant. However, if the pressure of the eye decreases due to blockage of the drainage angle, the continual influx of aqueous humor will cause the pressure inside the eye to increase potentially causing damage to the optic nerve.

Different types of glaucoma

Open-angle glaucoma – Open-angle glaucoma is the most common form of glaucoma. The “open” drainage angle of the eye can become blocked due the gradual increased eye pressure. This increased pressure results in optic nerve damage causing chronic open-angle glaucoma.

Angle-closure glaucoma – Angle-closure glaucoma results when the drainage angle of the eye narrows and becomes completely blocked. The iris may close off the drainage angle and cause a dangerously high eye pressure. When the drainage angle gets completely blocked, pressure builds up rapidly, and this results in acute-closure glaucoma.

Warning signs

The following signs are the main indications of glaucoma that indicates you need a thorough examination of one of the most professional eye doctors in phoenix AZ. They are:

  • Complexity in focusing near and distant object
  • Double vision, dry eyes with itching
  • Excessive watery eyes, recurrent pain in or around the eyes
  • Dark spots at the center of viewing
  • Color change in iris, trouble having adjusting to dark rooms
  • And more

Many other serious symptoms like sudden loss of vision in one eye, blurred vision, flashes of lights or black spots will need the attention of family doctors in Mesa AZ. All the symptoms listed above may not necessarily mean you have glaucoma. But in case you experience any one or more of these symptoms, you should contact your eye doctor as soon as possible for a complete examination. The most important risk factors responsible for this eye problem include age, elevated eye pressure, a thin cornea, past injuries to eyes, or a family history of glaucoma. Your eye doctor in phoenix AZ will consider these factors to determine your risk of developing this eye disease.
