Glaucoma is an eye disorder that cause severe blindness. There are multiple types of Glaucoma however, they all have something to do with damage to the optic nerve (usually form high eye pressure) that sends and receives information to the brain form the eye. Glaucoma can be a very dangerous disease although it is no fatal but it can contribute to the failure of one of the bodies most important senses which is blindness. In most cases, glaucoma is correlated with high pressure inside the eye (ocular hypertension),but it also can occur when intraocular pressure (IOP) is normal. If left untreated glaucoma first causes peripheral vision loss and eventually leads to total blindness.

Glaucoma is several eye conditions that can damage to your optic nerve. Increased pressure in the eye can cause glaucoma, which leads to vision loss or blindness (Healthline). There are five different types of glaucoma, which are open-angle (chronic) glaucoma, angle-closure (acute) glaucoma, congenital glaucoma, secondary glaucoma, and normal-tension glaucoma (Healthline). Open-angle (chronic) glaucoma is the most common type of glaucoma, and there are no signs or symptoms expect gradual vision loss (Healthline). People that over sixty years old are at risk for glaucoma, and African Americans risk starts at forty years old. There is no cure for glaucoma, but surgeries and medicine can help

This depends on how early or late patients are willing to receive a diagnosis from ophthalmologists. In early treatments, glaucoma is not curable, but there are methods to control its progression or to prevent the increased risk of blindness. What ophthalmologists aim for in treating this disease is decreasing intraocular pressure in one’s eye. Determined by the condition the patients are in, “options may include eye drops, laser treatment, or surgery.” The Prevent Blindness America Organization plays an extensive role in projecting awareness for glaucoma and in helping those to fight against it. They “conduct mass glaucoma screenings” and list possible medications such as beta-blockers and carbonic anhydrase inhibitors. These are used to decrease the quantity of aqueous fluid in the eye (Marks and Montauredes

Glaucoma is not about one eye dieses it effects on both eye, it’s very risky and its effects on eye really badly. When you have glaucoma you need to look for those kind effects going on. You can lose your eye vision then you won’t be able to see. So many people in United States they all lost their vision because of Glaucoma. It’s very important to get your check up done on your regularly appointment and have your doctor measure your intraocular pressure. If you have glaucoma in one eye and that can cause so much it can affect your other eye too and you will affect someone else too. Sometime people get caught if they have glaucoma to someone else in their family.

According to Vaughan & Ashbury’s General Ophthalmology, Glaucoma is characterized by the “optic disc cupping and visual field loss, usually associated with elevated intraocular pressure.” "In open-angle glaucoma, there is an imbalance in the production and drainage of the aqueous humor (clear fluid between the cornea and the lens) that fills the eyes anterior chamber." (Berdahl, John) In certain situations, too much aqueous is produced by the ciliary body inside the eye; and in other situations the drainage channels in the anterior chamber become impassable. Whichever the cause, the result is that the pressure inside the eye increases to perilous levels. When intraocular pressure increases, the pressure pushes harder against the nerve fibers of the optic nerve, which conveys visual information to the brain.

By using laser treatment it can delay the use of daily eye drops. Laser treatment is use to clear or open up the drainage canals that are lowering the movement of fluid in the eye. By clearing it up the eye pressure is lowered stoping the damage being caused to the optic nerve. Yet the effect of laser treatment is not permeant and the patient will eventually need to use eye drops.

The guidelines of the European Glaucoma Society (EGS) for the management of glaucoma due to corticosteroid treatment are; (1) discontinuation of corticosteroid therapy or switch to weaker steroid (2) administration of topical or systemic IOP lowering medications (3) laser trabeculoplasty and (4) glaucoma surgery in intractable cases. These recommendations are, however, not specific for intravitreal administration of

Left untreated it may cause blindness in one to two days. Phenylephrine is used as a decongestant that shrinks the blood vessels. It is not used for narrow angle glaucoma. is used to relieve eye redness, dryness, burning, and irritation caused by wind, sun, and other irritants. to

There are several types of glaucoma. The two main types of glaucoma, are open-angle glaucoma and angle-closure glaucoma. In open-angle glaucoma, the angle the angle in your eye where the iris meets, the cornea is as wide and open as it should be, but the eye’s drainage canals become clogged over time, causing an increase in internal eye pressure and later damaging the optic nerve. Angle-closure glaucoma is caused by a rapid or sudden increase in intraocular pressure (IOP), the pressure in the eye. A fluid is continually produced inside, and drains out of, the normal eye. The fluid, is called aqueous humor. Aqueous humor is not like tears, which are only on the outside of the eye.

"Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time". (WebMD) Glaucoma is interlinked with the pressure in the eye. No one knows the exact cause of the glaucoma. Doctors think the main cause of the glaucoma is the pressure in the eye. Some people with the normal eye pressure also suffer with glaucoma. There are different kinds of glaucoma such as open angle glaucoma, Angle closure glaucoma, Normal tension glaucoma, Congenital and infantile glaucoma, and secondary glaucoma’s. Beta–adrenergic blockers and prostaglandins are the most frequently used topical medications at present.

To fix eyes during the experiment, they were stuck on a support using cyanoacrylate glue and placed in a thermoregulated bath at 35◦C and submerged in PBS. Then, a 33G beveled needle was inserted in the AC to cannulate the

Glaucoma is the disease that causes optic nerve damage and eventually loss of vision. Most people do not realise they have glaucoma until they are diagnosed and already have some decreased field of vision. Depending on what type of glaucoma the diagnosis is there are some laser treatments that can be done to help lower the pressure in the eye. Ophthalmologist will decide if a laser treatment is appropriate for the patient on its own or alongside topical therapy. Lasers are a high concentration beam of light that helps open up the trabecular meshwork in order to release the pressure in your eye. The types of lasers are Select Laser Trabeculoplasty, Laser Peripheral Irdotomy, YAG Laser Cyclophotocoagulation

This usually starts with prescription eye drops. There are different classes of drugs used for glaucoma. Since the increased pressure in your eyes is caused by poor drainage of fluid, the medications affect drainage in different ways. Some drugs decrease the production of the fluid while others increase the rate at which it flows through the drainage fields in your eyes. Once you start medication for glaucoma, you'll need to have your eye pressures monitored regularly to make sure the condition is kept under control. You may need to have your medication changed or the dose adjusted as you

Treatment of open-angle glaucoma usually begins with prescription eyedrops. These eyedrops lower pressure inside the eyeball, either by causing the eye to produce less fluid or by helping fluid to drain more. As an alternative to medication or when medication does not control glaucoma, laser surgery can be done. This surgery, also called laser trabeculoplasty, uses a laser to make the openings in the eye's drainage network larger. If medication and laser surgery are unsuccessful, conventional eye surgery may be necessary to make a new opening for fluid to leave the eye.
