Acute Angle-Closure Glaucoma
What Is Glaucoma?
Glaucoma Overview
Glaucoma identifies a group of diseases that create damage on the optic nerve. Containing greater million nerve fibers, the optic nerve connects a person's eye to the brain. This important nerve is liable for carrying images to your brain.
The optic nerve fibers makeup a part from the retina which gives us sight. This nerve fiber layer might be damaged once the pressure of a persons vision (intraocular pressure) becomes excessive.
Over time, ruthless causes the nerve fibers to die, causing decreased vision. Vision loss and blindness will more than likely result if glaucoma is not dealt with.
Glaucoma Symptoms
Glaucoma has become nicknamed the "sneak thief of sight" as it often goes undetected and results in irreversible injury to the eye.
There tend to be no symptoms noisy . stages on the disease. Many people have glaucoma but are not aware about it.
As the illness progresses, vision may seem to fluctuate and peripheral vision fails. If not treated, vision may be reduced to tunnel vision and at last, total blindness.
Glaucoma Causes
Glaucoma usually develops when fluid in a persons vision builds up, causing higher pressure than the attention can withstand. The canal accountable for draining this fluid becomes plugged, preventing proper drainage.
In other cases, the attention may produce more fluid than normal and just cannot be drained fast enough, producing higher intraocular pressure.
Researchers are not aware of exactly what makes a lot of people more prone to this matter.
Other causes might include trauma, genetic disorders and low blood flow towards the optic nerve.
Risk Factors for Glaucoma
Having high intraocular pressure enhances the risk of developing glaucoma. Those who are four decades of age and older and who're African-American have an increased risk.
Anyone 60 years of aging is more in jeopardy, especially Mexican-Americans.
Furthermore, people that have a family good glaucoma have higher likelihood of developing glaucoma. Having systemic diseases for example diabetes, high blood pressure levels and heart related illnesses also increase your risk. Other risk factors include nearsightedness and direct trauma to the attention.
Types of Glaucoma

- Chronic glaucoma: Open-angle glaucoma damages the interest with no signals. It is the most frequent type of glaucoma and it is often referred to as the "silent type." Damage occurs with time, usually anytime.
- Acute closed-angle glaucoma: Closed-angle glaucoma happens quickly. An "attack" may build a red, painful eye and symptoms like facial pain, headache, blurry eyesight, rainbow-colored haloes around lights, nausea and vomiting. It is a severe medical emergency.
How Glaucoma Is Diagnosed
Your eye doctor might use tonometry or gonioscopy to evaluate for glaucoma.
- Tonometry: A key test in glaucoma diagnosis is tonometry. A tonometer measures eye pressure, more well known as intra-ocular pressure.
- Gonioscopy: Gonioscopy can be performed to consider the angle of a persons vision to detect whether it is open or closed. An inspection in the health from the optic nerve can also be important in assessing any damage that will have occurred on account of glaucoma. If damage is suspected, the physician may measure your general visual field using a computerized perimeter or analyze your nerve fiber layer with scanning laser ophthalmoscopy.
Glaucoma Treatment Options
The goal of glaucoma treatment solutions are to reduce eye pressure to your level from which no more damage occurs.
- Treatment is given inside the form of prescription eye drops and, occasionally, oral systemic drugs.
- Laser treatment has become shown to work equally as well as medicines to stop more damage from occurring.

- Many times therapy features a combination of these treatments.
It is significant to understand that glaucoma can not be cured, but is usually controlled. Unfortunately, vision loss due to glaucoma can not be reversed.
