Open-angle glaucoma:

Open-angle glaucoma is a chronic, progressive, and irreversible multifactorial optic neuropathy that is characterized by an open angle of the anterior chamber, optic nerve head changes, and progressive loss of peripheral vision, followed by central visual field loss. 

Causes

The causes of open-angle glaucoma include:

• The drainage system in the eye, responsible for fluid outflow, may become clogged or obstructed, leading to a buildup of fluid and increased intraocular pressure.
• The eye may produce an excessive amount of fluid, overwhelming the drainage system's capacity to remove it effectively. This can result in elevated intraocular pressure.
• The risk of developing open-angle glaucoma increases with age. The exact reasons for this are not fully understood but may involve changes in the structure and function of the eye's drainage system over time.
• Certain genetic mutations or variations have been associated with an increased risk of open-angle glaucoma. These genetic factors can influence the development and functioning of the drainage system.
• Having a family history of open-angle glaucoma can increase the likelihood of developing the condition. This suggests a possible genetic predisposition to the disease.
• People of African, Hispanic, and Asian descent have a higher risk of developing open-angle glaucoma compared to individuals of European descent. The reasons for this disparity are not fully understood and may involve genetic and environmental factors.
• Certain medical conditions, such as diabetes, high blood pressure, and cardiovascular diseases, have been associated with an increased risk of open-angle glaucoma. The underlying mechanisms linking these conditions to glaucoma risk are not yet well-defined.

Symptoms 

Glaucoma in the early stages usually doesn’t produce any symptoms. Damage to your vision can occur before you’re aware of it. When symptoms appear, they can include:

• reduced vision and loss of peripheral vision
• swollen or bulging cornea
• pupil dilation to a medium size that doesn’t change with increasing or decreasing light
• redness in the white of the eye
• nausea

These symptoms primarily appear in acute cases of closed-angle glaucoma but can also appear in open-angle glaucoma. Remember, absence of symptoms isn’t proof that you don’t have glaucoma.

Diagnosis

First, you get a numbing drop, since these tests use tools that touch your eyes. Then your doctor:

• Checks your eye pressure
• Looks for an open angle
• Measures the thickness of your cornea

You’ll then likely get a:

• Dilated eye exam, where you get a drop to make your pupil open wide. This lets your doctor see your optic nerve and check on its health.
• Visual field test to check your eyesight. You’ll repeat this over the years to see how your vision changes.
• OCT test to take a more in-depth scan of your optic nerve.
