Types of glaucoma with its symptoms and treatments

Today Glaucoma has become the second leading cause of blindness worldwide, affecting affecting more than 65 million people globally. Experts say that the major reason behind this is the negligence of the people towards eye symptoms. This eye disease symptoms if taken proper care at right time can stop vision loss that is caused due to glaucoma.

So to avoid Glaucoma and take proper care of eye we have to first understand the basic nature , symptoms, prevention and treatment for Glaucoma.

Glaucoma is a group of diseases that can damage the optic nerve of the eye and can result in vision loss and blindness. When the normal fluid pressure inside the eyes slowly rises then glaucoma occurs. There are several forms of glaucoma.

Normal tension or low-tension glaucoma : Normal-tension glaucoma (also called low-tension glaucoma) is a unique condition in which optic nerve damage and vision loss occurs despite of a normal pressure inside the eye. People with normal eye pressure, can experience optic nerve damage and narrowed side vision.
* People suffering with normal-tension glaucoma do not experience any early symptoms of it and so it becomes more important for us to go for regular eye check-ups as this situation can only be diagnosed with medical instruments.
* There is no cure for this disease but treatment may include some medicines which can slow the disease by lowering eye pressure of at least 30 percent.

Angle-closure glaucoma : Angle-closure glaucoma is a glaucoma that is associated with a closed anterior chamber angle, which may be chronic or, rarely, acute. People who have this type of glaucoma have a sudden increase in eye pressure, as the fluid at the front of the eye cannot reach the angle and leave the eye, and part of the iris blocks the angle.
* Symptoms include nausea, severe pain, blurred vision and redness. If we experience these symptoms, we should go for treatment immediately, as this is a medical emergency.
* Treatments include some medicines and prompt laser surgery which successfully clears the blockage and protect sight.

Congenital Glaucoma: Congenital glaucoma mainly occurs in children and is present and diagnosed at birth or shortly thereafter. Congenital glaucoma occurs by improper development of the eye's drainage channels (called trabecular meshwork). Because of this, the channels that normally drain the fluid (called aqueous humor) from inside eye do not function properly. More fluid is continually being produced but cannot be drained because of the improperly functioning drainage channels. This leads to high pressure inside the eye, called intraocular pressure (IOP).
* Symptoms that are associated with this disease are- excessive tearing, sensitivity to light, cloudy eyes.
* For treatment conventional surgery is preferred, as it is effective, safe, and if done promptly, can give children an excellent chance of having good vision.

Pigmentary glaucoma : This is one rare form of glaucoma. It is caused by the deposition of pigment in the iris that clogs the draining angles, preventing aqueous humor from leaving the eye. Over time, the inflammatory response to the blocked angle damages the drainage system.
* This disease shows no specific symptoms. Though some pain and blurry vision may occur after exercise.
* Treatment includes conventional surgery, medicines, and laser surgery.
