Primary open-angle glaucoma, bilateral

Primary open-angle glaucoma, bilateral, is a common eye disease that affects the optic nerve and can lead to blindness if left untreated. It is a chronic and progressive condition that is characterized by a gradual loss of vision due to damage to the optic nerve.

The condition is called "open-angle" because the angle between the iris and the cornea remains open, but the drainage channels in the eye become clogged, leading to increased pressure within the eye. This increased pressure, called intraocular pressure (IOP), can cause damage to the optic nerve, which is responsible for transmitting visual information from the eye to the brain.

Primary open-angle glaucoma, bilateral, is called "bilateral" because it affects both eyes. However, the disease may progress at different rates in each eye.


Primary open-angle glaucoma, bilateral, often has no symptoms in its early stages. As the disease progresses, however, symptoms may include:

  1. Loss of peripheral vision
  2. Tunnel vision
  3. Blurred vision
  4. Halos around lights
  5. Eye pain

If you experience any of these symptoms, you should see an ophthalmologist (eye doctor) immediately.


Primary open-angle glaucoma, bilateral, can be treated with medication, laser therapy, or surgery. The goal of treatment is to lower intraocular pressure and prevent further damage to the optic nerve.

Medications, such as eye drops, can be used to reduce intraocular pressure. Laser therapy, such as selective laser trabeculoplasty (SLT), can be used to improve the drainage of fluid from the eye, thereby reducing IOP. Surgery, such as trabeculectomy, can be used to create a new drainage channel for fluid to leave the eye.

It's important to note that treatment cannot reverse any vision loss that has already occurred, but it can help prevent further damage and preserve remaining vision.


Primary open-angle glaucoma, bilateral, is a serious eye condition that requires prompt diagnosis and treatment. While there is no cure for the disease, early detection and treatment can help prevent further damage and preserve remaining vision. If you are experiencing any symptoms of primary open-angle glaucoma, bilateral, be sure to see an ophthalmologist immediately.
