Glaucoma is a medical disease that damages your iris or the transparent covering of the eye. The iris is essential to the process of receiving light and processing visual information. The optic nerve provides visual information to the brain in your eyes from your eyes. Glaucoma symptoms can be caused by eye injuries, eye damage from infections, or trauma.
Glaucoma is the condition when the fluid pressure rises within the human eye. If glaucoma is not treated properly, it can lead to damage of the eye’s optic nerve and can lead to vision loss. When this optic nerve is damaged, it can no longer respond to normal optic nerve stimulation and continues to experience very sharp, unidirectional visions.
The attack occurs suddenly and abruptly disrupts normal daily activities including reading, computer use and talking. As the attack progresses, the pressure behind the eye gradually increases in intensity. Eventually, normal vision is restored only after the loss of vision has been extensive.
Though glaucoma is not really common, but most likely to affect older people between the age of 40 to the age of 60. If glaucoma develops, damage to the iris can impair your vision. In most cases, glaucoma generally is, but not necessarily, the result of unusually high pressure within your eye.
You can help prevent glaucoma and even reverse it if you catch it in the earliest stages possible. However, you cannot cure glaucoma, and even treatment may not eliminate glaucoma symptoms. Thus, it is important to treat glaucoma through an effective and timely eye care routine, especially if you are at risk of developing serious glaucoma.
Your doctor will consider many things, such as
- Your age
- Lifestyle factors
- Family history.
If these glaucoma symptoms occur, you should see a doctor immediately. Early detection of glaucoma greatly increases the chances of successful treatment of vision problems. In America, there are different types of glaucoma testing available to different people.
He or she will also consider whether you are experiencing any symptoms of eye problems, such as pressure within the eye, redness, sensitivity to light or any other unusual vision changes. Doctors look for the signs of glaucoma, which include
- Raised intraocular pressure, or IOP, with normal vision loss
- Increased pressure in your eye can result in any of the following:
- Impaired vision
- Blurred vision
- Myopia (nearsightedness)
- Hypermetropia (over-sighting)
- Hypertrichosis (hairspray dermatitis).
Some individuals experience only one or two of these glaucoma symptoms. But for others, all of these glaucoma symptoms could be present.
Glaucoma is caused by open angle-closure has no symptoms. The leading cause of glaucoma and the only way to prevent the disease is to avoid any lifestyle factors that put you at risk for glaucoma. As the leading cause of vision loss, glaucoma can affect anyone.
The eye symptoms that arise are
- Blurred vision
- Burning or stinging pain
- Sensitivity to light
However, people who have a family history of the disease are much more likely to develop it. People who smoke and those who drink heavily are also at higher risk of experiencing any of the glaucoma symptoms. If you smoke, you are at a higher risk of contracting glaucoma.
If you have family members who have had glaucoma, you are at a higher risk as well. Another key indicator is if you experience any pain, pressure inside your eyes. This pain is caused by fluid building up and putting pressure inside the eye. If you have these glaucoma symptoms, you should schedule an eye check-up immediately.
Early detection can help save you from serious glaucoma later on. Some glaucoma symptoms do not necessarily mean that you have glaucoma. They can also be caused by other medical conditions. Some other medical conditions include cataracts and macular degeneration.
There are times when you may not have nerve damage and a simple eye exam will not give you a clear answer. However, it is still important to have this examination, just in case you have damage to your vision. Nerve damage is often the result of glaucoma. If you feel any numbness or tingling in your eyes, you should immediately report back to your doctor. With some simple treatment options, you can find that you are not blind after all.
Acute angle-closure glaucoma occurs in older adults and frequently affects people with angle-closure glaucoma. This condition is called angle-closure glaucoma and occurs as either primary (onycholysis) or secondary glaucoma. The disease is the result of an injury to the drainage tract of the eye or to one of its valves.
Occurring in approximately every 100,000 individuals, acute angle-closure glaucoma accounts for more than half of all cases. However, it is rarely discovered early because the glaucoma symptoms are often so subtle that they are not easy to spot.
Thus, treatment of acute angle-closure glaucoma typically requires surgical intervention. When the optic nerve is affected by acute angle-closure glaucoma, damage occurs very quickly. These are vision screenings, medical procedures, and ophthalmologist examinations.
Vision screenings can be done easily at home and can accurately determine if you have glaucoma or not. Medical tests, on the other hand, are more complicated and requires highly experienced doctors to perform. Most people undergo routine eye exams to monitor the progress of their eyesight.
In primary acute angle-closure glaucoma, the opening of an aqueous canal prevents normal drainage of the eye’s optic nerve. When this occurs, pressure builds behind the eyelids and eventually causes blindness. This is often the result of damage to one of the drainage canals, which can be either due to intrinsic or extrinsic factors.
Intrinsic factors are those that occur naturally with age
- A buildup of intraocular pressure (IOP)
- Myocardial infarction (MI)
- Hypertension and atherosclerosis
Intrinsic factors are generally easy to correct through medications or surgery. Extrinsic factors on the other hand, such as excess aqueous in the ocular discharge, are difficult to correct and often require surgical intervention.
There are four types of intraocular pressure
- The first is intraocular pressure (IOP) which is normal and maintained throughout life
- The second is called the medial intraocular pressure (MIA), which is also normal but becomes elevated during an attack, reaches a peak during an attack and then drops below normal during the preceding phase
- The third is called optic nerve protopathy (ONP), which refers to glaucoma caused by damage to the optic nerve
- The fourth and rarest type of glaucoma, extrinsic angle-closure glaucoma (EAGV), occurs when there is no direct contact between the eye and an object
This type of glaucoma can lead to severe damage to vision. The treatment for acute angle-closure glaucoma depends on the severity of the optic nerve proctopathy. For milder cases, laser peripheral iridotomy may be enough to treat the disease.
Acute Angle-Closure Glaucoma
There are many different risk factors that make people more likely to develop acute angle-closure glaucoma. They include
- Family history of CVA
- Alcohol use
- Past or present use of antibiotics
People who smoke, have diabetes, experience hypertension, have or use alcohol or have any other medical conditions at the same time as the patient is also at a greater risk for developing this disease. A common sign of glaucoma in the affected eye is blurred vision, along with nausea and vomiting.
Glaucoma testing can determine if you are at a higher risk of contracting glaucoma. A glaucoma test is required in every state of America. When glaucoma develops in your eye, you should immediately consult your eye doctor for appropriate treatment.
However, if you develop glaucoma without having any previous glaucoma symptoms, you have to learn about it. Learning about glaucoma will help you understand it and to deal with it properly. Hence, it is important to learn all about glaucoma as early as possible.
Glaucoma Symptoms Risks
Glaucoma patients should know their risks, and understand what to do if they are diagnosed with this condition. If you have high intraocular pressure, your doctor may recommend that you undergo eye drops that lower the pressure in the eye, or that you receive intraocular pressure stimulation or AIPS.
These treatments aim to increase the drainage of pressure from the eye, in addition to medication. Other treatment options your doctor may suggest include laser surgery, or drainage through a catheter. However, if the IOP goes too high, you may not be able to opt for any of these treatment options and will have to opt for surgery to correct your IOP.
However, if your IOP is too low, the optic nerve is damaged, or your eye’s drainage does not improve the vision, you will need to opt for surgery. Two types of glaucoma commonly exist. Either iris-type glaucoma causes increased pressure inside the eye, or thrombophlebitis, which affects the blood supply to the eye.
If the increased pressure within the eye causes damage to the optic nerve, or if the optic nerve is damaged, then you may need to opt for eye surgery to correct your vision. If you’re diagnosed with glaucoma, you will undergo a routine eye examination first.
During this time your doctor will check for any problems such as
- Refractive errors
- Visual field tests (VFT), and the results of tests such as ophthalmological Sinusoscopy and cranial CT scan.
Once your visual field test and the results of your ophthalmological Sinusoscopy are positive, your doctor will likely schedule an overnight visit to perform a more comprehensive exam. During this time your doctor will either begin drainage or begin treatment.
Glaucoma patients can expect either temporary or permanent vision loss, depending on how severe their glaucoma symptoms are. Temporary glaucoma symptoms include redness, blurred vision, increased sensitivity to light, and headache. These glaucoma symptoms generally subside over time.
However, if you experience frequent redness, blurred vision, increased sensitivity to light, headaches, or decreased vision after the onset of glaucoma symptoms, you may have glaucoma and will require immediate treatment. Permanent damage to the eye, caused by glaucoma, generally occurs over time.
Presently, there is no cure for glaucoma, but the treatment can slow or stop the progression of glaucoma. There are many types of glaucoma. However, not all types are the same. These various types of glaucoma are divided into four types
- Congenital glaucomas, with no apparent cause
- Open-angle glaucoma, in which the angle of the opening is larger than normal, leading to increased pressure inside the eye
- Angle-closure glaucoma, in which the clumps of the optic nerve are surrounded by an iris, rather than by a ring of tissue
- Closed-angle glaucoma, where the iris does not close
In all types of glaucoma surgery is required to correct the problem. There are various types of treatment available for congenital glaucoma. However, it depends upon the age, grade and size of the optic nerve at the time of detection.
The best treatments for these types of glaucoma are Vitamin and Herbal medicines, with or without surgery. These medicines can improve intraocular pressure, relieve pain and pressure on the fundus, facilitate passage of food and liquid, provide relief from cough, help relieve straining and swelling, and reduce intraocular pressure.
