Open-angle glaucoma is the most common type of glaucoma. It often progresses without noticeable symptoms, earning it the nickname "the silent thief of sight." In this condition, the angle between the iris (colored part of the eye) and cornea (clear front part of the eye) is open, but the fluid inside the eye drains slowly, causing a gradual increase in eye pressure.

 

 

Silent nature: In the early stages, open-angle glaucoma often has no symptoms.

Gradual progression: The increased eye pressure gradually damages the optic nerve, eventually leading to vision loss.

Irreversible damage: Once damaged, optic nerve cells cannot regenerate, making any damage permanent.

 

Risk factors for open-angle glaucoma

 

Age: Older adults are at higher risk.

Family history: A family history of glaucoma increases the risk.

Race: Certain races, such as African Americans, have a higher risk.

Diabetes: People with diabetes are at increased risk.

High blood pressure: High blood pressure can damage the optic nerve.

Eye injuries: Eye injuries can increase the risk of developing glaucoma.

 

In the early stages, open-angle glaucoma typically has no symptoms. As the disease progresses, symptoms may include:

 

Blurred vision, especially in peripheral vision

Halos around lights

Decreased night vision

 

Early detection of open-angle glaucoma is crucial. An ophthalmologist will use the following tests to make a diagnosis:

 

Intraocular pressure measurement: To measure the pressure inside the eye

Gonioscopy: To examine the angle between the iris and cornea

Perimetry: To assess your field of vision

Optic nerve imaging: To evaluate damage to the optic nerve

 

The goal of treatment is to lower eye pressure and prevent further vision loss. Treatment options may include:

 

Medications: Eye drops to lower eye pressure

Laser surgery: To create a new drainage pathway for fluid in the eye

Traditional surgery: In cases where medications and laser treatments are ineffective

 

Regular eye exams are crucial for early detection and treatment of open-angle glaucoma. This is especially important for those with a family history of glaucoma or who fall into high-risk groups. Open-angle glaucoma is a serious condition that can lead to blindness if left untreated. Early detection and treatment are essential.
