Types of Glaucoma:
Primary Open-Angle Glaucoma
This is the most widely recognized type of glaucoma, influencing around three million Americans. It happens when the eye's waste trenches get to be distinctly stopped up after some time.
The internal eye weight (likewise called intraocular weight or IOP) rises in light of the fact that the right measure of liquid can't deplete out of the eye. With open-edge glaucoma, the doors to the waste channels are clear and ought to work effectively. The stopping up issue happens to assist inside the waste trenches, like an obstructed pipe beneath the deplete in a sink.
A great many people have no side effects and no early cautioning signs. On the off chance that open-edge glaucoma is not analyzed and treated, it can bring about a steady loss of vision. This kind of glaucoma grows gradually and once in a while without recognizable sight misfortune for a long time. It more often than not reacts well to the drug, particularly if got early and treated.

This sort of glaucoma is otherwise called intense glaucoma or limited point glaucoma. It is a great deal more uncommon and is altogether different from open-edge glaucoma in that the eye weight more often than not rises rapidly.
This happens when the seepage trenches get blocked or secured over, similar to a sink with something covering the deplete.
With edge conclusion glaucoma, the iris is not as wide and open as it ought to be. The external edge of the iris bundles up over the waste waterways when the understudy extends an excess of or too rapidly. This can happen when going into a dim room.
A basic test can be utilized to check whether your edge is ordinary and wide or irregular and restricted.
Side effects of edge conclusion glaucoma may incorporate cerebral pains, eye torment, sickness, rainbows around lights during the evening, and extremely obscured vision.
Treatment
Treatment of edge conclusion glaucoma, for the most part, includes either laser or customary surgery to expel a little segment of the bundled up external edge of the iris. Surgery unblocks the waste trenches so that the additional liquid can deplete.
On the off chance that you have point conclusion glaucoma in one eye, specialists may simply ahead and regard the other eye as a security measure.
As a rule, surgery for edge conclusion glaucoma is fruitful and enduring. Normal checkups are still vital, however, on the grounds that an unending type of glaucoma could in any case happen.

Normal-Tension Glaucoma
Specialists don't know why a few people's optic nerves are harmed despite the fact that they have practically ordinary weight levels.
Those at higher hazard for this type of glaucoma are:
individuals with a family history of ordinary pressure glaucoma
individuals of Japanese family
individuals with a background marked by systemic coronary illness, for example, unpredictable heart beat.
How Normal-strain Glaucoma is Different
Glaucoma is a gathering of eye ailments that for the most part share normal characteristics, for example, high eye weight, harm to the optic nerve and steady sight misfortune. Most sorts of glaucoma include lifted eye weight.
Ordinary strain glaucoma (NTG), otherwise called low strain or typical weight glaucoma, is a type of glaucoma in which harm jumps out at the optic nerve without eye weight surpassing the typical range. By and large, a "typical" weight territory is between 12-22 mm Hg.
What Causes Normal-pressure Glaucoma?
The reasons for NTG are still obscure. For reasons unknown, the optic nerve is powerless to harm from even the ordinary measure of eye weight. Specialists keep on examining why some optic nerves are harmed by these generally low eye weight levels.
How Normal-strain Glaucoma is Diagnosed:
NTG is analyzed by watching the optic nerve for indications of harm. This should be possible in one of two ways.
In one technique, an instrument called an ophthalmoscope is held near the eye. In an obscured room, the light from the ophthalmoscope permits the specialist to look through the understudy and inspect the shape and shade of the optic nerve. A nerve that is measured or is not a solid pink shading is a reason for concern.
A moment methodology is the visual field test. This test delivers a guide to the patient's total field of vision. Utilizing this test, the specialist can check for any ranges of sight misfortune that might be brought on by harm to the optic nerve. This would show up as slight changes in the individual's vision happening anyplace from close to the middle to the edge of the field of vision. These progressions are not really discernible to the patient.
How Normal-strain Glaucoma is Treated
Since so little is thought regarding why typical eye weight harms a few eyes, most specialists treat ordinary strain glaucoma by decreasing the eye weight as low as conceivable utilizing prescriptions, laser medicines, and customary surgery.

Other Types of glaucoma:
Most different sorts of glaucoma are varieties of open-edge or point conclusion sorts. These sorts can happen in either of your eyes.
Optional glaucoma
Optional glaucoma alludes to any case in which another illness causes or adds to expanded eye weight, bringing about optic nerve harm and vision misfortune.
Optional glaucoma can happen as the aftereffect of an eye damage, irritation, tumor, or in cutting edge instances of waterfall or diabetes. It can likewise be brought on by specific medications, for example, steroids. This type of glaucoma might be gentle or serious. The kind of treatment will rely on upon whether it is open-point or edge conclusion glaucoma.
Perused more about optional glaucoma.
Pigmentary Glaucoma
Pigmentary Glaucoma is a type of optional open-point glaucoma. It happens when the shade granules that are in the back of the iris (the hue some portion of the eye) break into the reasonable liquid created inside the eye. These modest shade granules stream toward the seepage channels in the eye and gradually stop up them. This causes eye weight to rise. Treatment more often than excludes prescriptions, laser surgery, or customary surgery.
Perused more about pigmentary glaucoma.
Pseudoexfoliative Glaucoma
This type of optional open-point glaucoma happens when a flaky, dandruff-like material peels off the external layer of the focal point inside the eye. The material gathers at the point between the cornea and iris and can stop up the waste arrangement of the eye, bringing about eye weight to rise. Pseudoexfoliative Glaucoma is normal in those of Scandinavian drop. Treatment, for the most part, incorporates solutions or surgery.
Perused more about exfoliative glaucoma.
Traumatic Glaucoma
Harm to the eye may bring about auxiliary open-edge glaucoma. Traumatic glaucoma can happen quickly after the damage or years after the fact. It can be brought about by limit wounds that wound the eye (called limit injury) or by wounds that infiltrate the eye.
Also, conditions, for example, extreme astigmatism, past damage, disease, or earlier surgery may make the eye more helpless against a genuine eye harm.
Perused more about traumatic glaucoma.
Neovascular Glaucoma
The unusual arrangement of fresh recruits vessels on the iris and over the eye's waste channels can bring about a type of auxiliary open-point glaucoma.
Neovascular glaucoma is constantly connected with different irregularities, regularly diabetes. It never happens all alone. The fresh recruits vessels obstruct the eye's liquid from leaving through the trabecular meshwork (the eye's seepage waterways), bringing on an expansion in eye weight. This kind of glaucoma is exceptionally hard to treat.
Irido Corneal Endothelial Syndrome (ICE):
This uncommon type of glaucoma typically shows up in just a single eye, instead of both. Cells on the back surface of the cornea spread over the eye's seepage tissue and over the surface of the iris, expanding eye weight and harming the optic nerve. These corneal cells likewise frame bonds that predicament the iris to the cornea, additionally obstructing the seepage channels.
Irido Corneal Endothelial Syndrome happens all the more much of the time in light-cleaned females. Side effects can incorporate dim vision after arousing and the presence of radiances around lights. Treatment can incorporate prescriptions and separate surgery. Laser treatment is not viable in these cases.
Inborn Glaucoma (Childhood Glaucoma):
Adolescence Glaucoma alludes to the nearness of glaucoma in a youngster and happens in 1 out of each 10,000 births in the United States. Innate glaucoma is the normal term utilized for glaucoma analyzed in earliest stages or early adolescence.
This glaucoma is brought about by irregular intraocular liquid seepage from the eye therefore of a blocked or blemished trabecular meshwork (the work like waste waterways in the eye). Intrinsic glaucoma might be because of an inherited deformity or unusual improvement amid pregnancy.
In different cases, an irregular waste framework might be the aftereffect of some other infection in the eye which brings about optional glaucoma. In these cases, glaucoma might be related with conspicuous iris (the hue some portion of the eye), corneal, or other eye issues.
In an uncomplicated instance of inborn glaucoma, microsurgery can frequently amend the auxiliary deformities. Different cases are treated with prescription and surgery.
