Glaucoma is the most common disease of eye after cataract. Many of you must be waiting to know this disease in a more detailed manner, and ofcourse in simpler language which often other medical journal articles would not provide you. So in next few minutes browse down the lines, and get to know what glaucoma is? Therefore from the next time onwards you dont mix up with the basic concept regarding glaucoma.
How it happens ?
Glaucoma is mainly caused due to increase in pressure due to the greater accumulation of eye water (aqueous humor). The entire concept is technically known as intraocular pressure (IOP). Though it is not the only cause of glaucoma. It has been found that normal eye pressure is 16 and patients who are affected with glaucoma is generally (please mark the word generally) is 25. It is to be told that people are there who have high IOP, may not suffer from glaucoma. But having an IOP of 25 increases about 13 times his or her chance of contracting glaucoma than that of a person having IOP 15.
This causes the anterior portion of the eye to push up or pull out of the eye cavity which results in pain and blurred vision in initial stages. Glaucoma in chronic cases may lead to blindness.
The main reason for increase in pressure inside eye is due to the failure of drainage inside the eye either due to blockage of the drainage path of eye that is known as trabecular meshwork, or the inability of the fluid to escape due to some other reasons.
Now as this pressure increases it gets conveyed to the inner eye too, and towards the optic nerves. These might after being exposed to enhancing pressure may get damaged leading to loss of vision.
How many types of glaucoma are there?
- Acute angle glaucoma
- Open angle glaucoma
Who can get Glaucoma?
Glaucoma most often occurs in adults over age 40, but it can also occur in young adults, children, and even infants. In African-Americans, glaucoma occurs more frequently and at an earlier age and with greater loss of vision.
You are at an increased risk of glaucoma if you:
- Are of African-American, Irish, Russian, Japanese, Hispanic, Inuit, or Scandinavian descent.
- Are over age 40.
- Have a family history of glaucoma.
- Have poor vision.
- Have diabetes.
- Take systemic corticosteroid medications, such as prednisone.
When you need to get alert?
If you have any of the following symptoms, seek immediate medical care:
- Seeing halos around lights
- Narrowing of vision (tunnel vision)
- Vision loss
- Redness in the eye
- Eye that looks hazy
- Nausea or vomiting
- Pain in the eye
Treatments and diagnosis for glaucoma
For diagnosis of glaucoma, its the best idea to contact an opthalmologist.
Modern treatments relies on some specified drug usage, surgeries [eye.taragana.net/?p=1935&preview=true] and lasik surgeries [eye.taragana.net/?p=1934&preview=true] . Some of the modern drugs are also under examination.
Although it might seem to be very dangerous, but if you ask me about the chances of its cure I would say from a personal experience that it is curable. My uncle contracted glaucoma ten years back and he suffered from it for about a month or two, and was cured with no follow up infections. And he is currently having no problem, with his vision. But remember this fact he consulted his doctor at a very initial stage, and so you can see his cognigance paid him. So its our call dont try ti to suppress or neglect the disease but to go for a consultation.
