There is only one type of glaucoma
There are four types of glaucoma; open-angle glaucoma, closed-angle glaucoma, secondary glaucoma, and congenital glaucoma.
Which is the most common type of glaucoma?
Open-angle glaucoma is the most common type of glaucoma. In this type, the increase in pressure is often small and slow. The cause is unknown. The increase in eye pressure happens slowly over time, which you cannot feel it. The increased pressure pushes on the optic nerve. Optic nerve damage causes blind spots in the vision. People with family history and people of African descent are at higher risk for this disease.
People with closed-angle glaucoma develop symptoms slowly over time.
People with closed-angle glaucoma initially develop the following symptoms, which come and go and steadily become worse:
- Sudden pain in one eye
- Decreased or cloudy vision (called "steamy" vision)
- Nausea and vomiting
- Rainbow-like halos around lights
- Redness in the eye
- Eye feels swollen
Glaucoma is a disease related to ____________
Glaucoma is a disease related to eyes.
What are the typical symptoms that appear in babies with congenital glaucoma?
The following symptoms typically appear when the child is a few months old:
- Cloudiness of the front of the eye
- Swelling of one eye or both eyes
- Redness in the eye
- Sensitivity to light
Congenital glaucoma occurs in babies.
Congenital glaucoma occurs in babies. It is caused when the eye does not develop normally. Sometimes, it is present at birth. It often runs in families.
Glaucoma is the leading cause of blindness in children
Glaucoma is the leading cause of blindness in older people of over 60 years. Early detection and treatment can prevent glaucoma.
Glaucoma is a group of eye conditions that damage ___________
Glaucoma is a group of eye conditions that damage the optic nerve. This nerve sends the images you see to your brain. Most often, optic nerve damage is caused when fluid builds up in the front part of your eye. That extra fluid increases the pressure in your eye and damages the optic nerve. This is called intraocular pressure.
Which one of the following is a symptom of open-angle glaucoma?
There are no signs or symptoms in people with open-angle glaucoma. This disease develops slowly without symptoms, but people with it experience blurred vision, distorted vision, or vision loss.
Which of the following causes optic nerve damage?
Optic nerve is damaged when fluid builds up in the front part of the eye. The front part of the eye is filled with a clear fluid called aqueous humor. This fluid is made in an area behind the colored part of the eye (iris). Aqueous humor leaves the eye through channels where the iris and cornea meet. This area is called the anterior chamber angle, or the angle. If anything slows or blocks the flow of this fluid, pressure builds up in the eye and optic nerve gets damaged.
11. Depending on the cause, secondary glaucoma symptoms can either be like open-angle glaucoma or closed-angle glaucoma.
Symptoms of secondary glaucoma depend on the underlying problem causing the glaucoma. Depending on the cause, symptoms may either be like open-angle glaucoma or closed-angle glaucoma.
