There are two common types of glaucoma: open-angle, and angle-closure. Both types of glaucoma are very serious and can cause vision loss if not treated. Some people are at higher risk than other for glaucoma. due to the nature of glaucoma, it is important to schedule routine eye examines if you are at risk.
People at risk
- 40 years old +
- Have had an eye injury
- Family members with glaucoma
- African or Hispanic heritage
- Have diabetes / migraines / poor blood circulation or other whole-body health problems
Also known as "the sneak thief" due to no early warning signs or symptoms. Open-Angle Glaucoma occurs when there is either a sustained increase in fluid production or a decrease in fluid drainage. With this imbalance in fluid flow, there is an increase in the intraocular pressure, which in turn reduces the blood flow in the sensitive tissues of the optic nerve. Over time, as the optic nerve fibers are destroyed, peripheral (side) vision is lost.
For many patients, the will leave with glaucoma without noticeable sight loss or discomfort in the eyes for many years. According to the Glaucoma Research Foundation, open-angle glaucoma affects nearly 4 million Americans; with many of those 4 million do not know they have the disease.
Sadly, once a patient is aware of vision loss the disease is very advanced. Due to the nature of glaucoma, vision loss is permanent -both medication and surgery cannot regain the vision that was lost.
However, if caught early through eye exams, your doctor can prevent vision loss. Routine eye exams are very important - especially if you are at risk.
When the eye's drainage angle is closed in different areas of the eye pressure begins to increase. As pressure increases the optic nerve is damaged and can result in vision loss.
Glaucoma damage to the eye can happen suddenly, known as acute attack, or gradual.
Signs of Angle-Closure Glaucoma
- Hazy / Blurred vision
- Rainbow circles around bright lights
- Severe eye and head pain
- Nausea / Vomiting
- Sudden sight loss
If you experience these signs, you need to contact an eye doctor immediately. The sooner glaucoma is spotted the better chance of stopping vision loss.
How Glaucoma Affects Your Vision
As the optic nerves become more damaged a blank spot will appear before your field of vision. As the optic nerve continues to damage, the blank spot will continue to grow larger.
