Glaucoma Disease is one of the many eye related diseases which, if identified in time, can be treated. If left untreated it can cause irreparable harm to the eye, and consequently loss of vision of the person. Basically, glaucoma disease damages the main nerve, i.e., the optic nerve, which links the eye to the brain. This is the nerve that transmits the images to the brain for interpretation.
There is some fluid present in the eye ball. When the pressure of fluid in the eye ball exceeds the normal range, this nerve, which is attached to the eye ball, can get damaged. In medical terminology, the pressure of the fluid present in the eye is referred to as intraocular pressure.
When this pressure exceeds the normal range, i.e., 21 mmHg, the patient is said to suffer from ocular hypertension. Although the normal range is closer to 21 mmHg, there are people who do not develop this disease even when intraocular pressure is much below or much above 21 mmHg. Normally, glaucoma blindness occurs very gradually, and the patient may not experience any pain identifiable with vision. This is the reason it is hard to treat it in time. This type of glaucoma blindness is very common in the US. Medically, it is also referred to as open-angle glaucoma.
Closed-angle glaucoma disease is more common in other parts of the world, especially in Asian countries. In this condition, the patient experiences acute pain in his or her eye for some time. The eye becomes red, and the patient may complain of headaches and vomiting sensation. Thereafter the vision becomes hazy very rapidly. The patient starts seeing halo like rings around lights. His or her pupil dilates, and it suddenly stops at the center of the eye. This would be a medical emergency. However, it rarely comes to this situation because the patient seeks medical help due to glaucoma headache.
Generally glaucoma is found in people above 50 years of age. Almost one out of every 200 individuals in that age group may suffer with this condition. The ratio increases rapidly in individuals who are 80 years or older. This does not mean that there are no cases of infant glaucoma.
The eyes are sensitive parts of our body, and unfortunately, there are various diseases relating to them. One such disease is glaucoma. Let us start by explaining in simple terms what is glaucoma. Basically the glaucoma disease is a situation where the optic nerve is damaged. This is generally caused due to what is referred to as intraocular pressure, that is abnormally high pressure inside your eye. There are different types of glaucoma, including primary Open-Angle Glaucoma, the Angle-Closure glaucoma, the Low-Tension Glaucoma Disease and the Pigmentary Glaucoma.
There are a number of risk factors, which may contribute to some people being more prone to suffer from the glaucoma disease. These include people who have high eye pressure, those who suffer from diabetes, and those who are nearsighted. If you have some other eye disease, you may be at a risk of developing glaucoma too. There is also congenital glaucoma, which makes people who have relatives suffering from the disease more prone to develop it too. If left untreated, glaucoma can cause a loss of vision and it may even cause blindness. Therefore, it is important to note that glaucoma should definitely not be taken lightly. Unfortunately in most cases there will just be a slight loss of vision and one may not even take much notice.
Some end up seeking medical advice once the disease has actually reached quite an advanced stage. Other symptoms which should alert you of possible problems include a blurred vision, seeing halos around lights, nausea and severe headaches. It is crucial to visit an ophthalmologist even at the most minimal signs. It is recommended that one gets his eyes examined on a regular basis. The eye specialist will be able to carry out an extensive check-up so as to discern whether you are suffering from the glaucoma disease, or any other eye problem. Early diagnosis and suitable treatment will help to reduce the probability of suffering extensive damage from malignant glaucoma.
