Glaucoma Glaucoma is a disease that affects the eye. It causes damage to the optic nerve which sends images to the brain. The nerve is damaged by intraocular pressure, pressure in the eye. If left untreated, glaucoma can cause vision loss. There are two main types of glaucoma, open-angle or wide-angle glaucoma and angle-closure or narrow angle glaucoma. Open-angle glaucoma is the more common of the two. In open-angle the eye appears normal, however, fluid does not flow properly through the trabecular passage. Angle-closure is a sudden buildup in eye pressure. Drainage is bad because the space between the iris and cornea is too small. There are sixty million people worldwide with glaucoma. There are 2.2 million in the United States. 8.4 million people were blind from glaucoma in 2010. Glaucoma can occur at any age but people that are over the age of 45 have a higher risk of getting it. People of different ethnicities have higher risks of glaucoma. The groups at risk are African Americans, Hispanic and Asian populations. Also if there has been prior injury to the eye there are higher risks. The symptoms of Glaucoma change according to the different types. Open-angle glaucoma only has one symptom. That symptom is the loss of sight. In most cases peripheral vision is lost before the central vision. The problem is that the patient may not notice the loss of vision and the disease will get severe. Closed-angle glaucoma has more mild symptoms, however there are severe symptoms. The symptoms of CAG include vision suddenly getting blurry, pain, nausea, and halos around lights. Symptoms can affect either one eye or both. Some symptoms of congenital glaucoma include watery eyes, cloudy appearance to the eye, and enlarged eye size. There are multiple ways that a doctor can test for glaucoma. These different procedures are aided by tools to help image the eye. These tools can expose the disease before symptoms occur. The first type is a tonometry. Tonometry measures the pressure of the eye. The patient sits resting their chin and forehead against rests to keep the head steady. In certain forms a probe is placed on the cornea to test the pressure. In a no touch tonometry a puff of air is blown in the eye. Next is a visual field test. This form is useful in testing because in glaucoma patients often lose peripheral vision first. This type of test can help determine if the vision is being lost. In this test the patient is asked to look at a computer screen and press a button whenever they saw a flash of light. With that information doctors can see the field of vision. One of the most important methods in diagnosing glaucoma is an ophthalmoscopy. The doctor can look at the optic nerve through the pupil. Doctors can then see if glaucoma is there or how bad it is. There are many different procedures of laser surgery for glaucoma. The first of these is a laser iridotomy. A laser iridotomy is where a hole is made in the iris to allow fluid drain normally. Next is Laser trabeculoplasty. This is only done in open-angled. Laser burns on the angle make a better passage for fluid to drain. It only lasts for around two years. The procedure would then be redone. Laser trabeculoplasty has two types, argon laser trabeculoplasty and
Age-related macular degeneration (ARMD)
Blocked tear duct
Corneal abrasion (or dystrophy)
Corneal ulcers and infections
Damaged nerves or blood vessels in the eye
Diabetes-related damage in the eye (diabetic retinopathy)
Lazy eye (amblyopia)
There are five tests done to determine if a patient has glaucoma. The first is Tonometry which measures the pressure within your eye.…
For example, marijuana can help cancer patients in numerous ways. Patients who undergo chemotherapy often vomit and feel nauseated. These are the two most noticeable benefits of medicinal marijuana. It is also said with the depression of having cancer. Marijuana also helps cancer patients by increasing their appetites. Patients who go through chemotherapy usually lose weight. In the last few years, studies have shown that the chemicals in marijuana actually fight cancer cells.…
This essay has shown various medical benefits marijuana offers such as pain relieve, glaucoma therapy and appetite stimulation. It has also discussed marijuana’s negative effects on development of psychosis, cognition and behaviour in adolescents. As an illicit drug, most studies were focused on the negative aspects of marijuana and the same fact has made empirical studies difficult to conduct. In turn, the negative effects of marijuana are overshadowing the positive anecdotal ones.…
You’ll learn how marijuana helps medically with cancer, asthma, Alzheimer’s, and glaucoma patients with their everyday pains, and slower the process of the illnesses. Which is why it should be legalized to continue helping with those types of illnesses, sicknesses, and pains.
Marijuana is used as a medical assistant. Our bodies contain a regulatory frame work called the endo-cannabinoid system. This system maintains the balance of the homeostasis in the body.…
Some people however, say that it serves as a great form of pain relief for patients with arthritis, glaucoma… etc. I will be disproving some of the reasons why medical marijuana shouldn’t be available for purchase.
Many of the elderly who have nausea, spasticity, glaucoma, movement disorders, and arthritis use marijuana to have some relief from their symptoms. I don’t think this is a very smart thing to do.…
After smoking small amounts of marijuana, patients are said to be relaxed and stress free, unlike alcohol which is depressant, Cannabis can be used to treat low level depression. Most depression is caused by stress; smoking marijuana relieves stress and thus relieves depression. Glaucoma is yet another disease that smoking marijuana will treat. Glaucoma is an optical disease that leads to permanent damage of the nerve ending and resulting visual fields, which progress to blindness.…
A federal Judge James Washington ruled that Randall’s use of marijuana constituted a medical necessity (Schaffer, 1976) Randall was affected with a medical condition called glaucoma. Glaucoma is defined by Henry D. Jampel, MD, MHS of the Glaucoma Research Foundation to be a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss (Jampel, 2013). Glaucoma is the second leading cause of blindness.…
They can be prescribed for patients going through chemotherapy and having loss of appetite, nausea, or vomiting. Marinol is also approved to treat HIV patients with cachexia. Marijuana has also been used for glaucoma to lower intraocular pressure, but research does not show that marijuana has a better effect than currently approved glaucoma medications.
