Glaucoma Research Paper

Glaucoma is caused when fluid is overproduced and it can't flow out at its normal rate which causes pressure to build up.

How does the progression of optic nerve and RGC damage translate to the clinical symptoms of glaucoma? In a study published by Harwerth and Quigley in 2006, the structure-function relationships of human glaucoma and experimental glaucoma in monkeys are compared, in order to discern a possible correlation between the progressive loss of visual field experienced by glaucoma patients and the gradual neural losses. Previous studies had suggested a large amount of variance between the well-defined relationship of experimental glaucoma and the slightly different system of clinical glaucoma, but the discrepancies could have equally resulted from different methods of data analysis, which would affect the precision of the results. The study compared

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.

Recommendation Statement “glaucoma affects approximately 2.5 million Americans and is a leading cause of impaired vision (loss of peripheral vision) and blindness” (Moyer). Glaucoma is a disease the damages the optic nerve in the eye. There are several different types of glaucoma including: Open-angle, normal-tension, closed-angle, and congenital glaucoma. Open-angle is the most common. Even though there is no treatment yet for glaucoma, a person can manage it. To help a person mange this disease there are two basic treatments that can be used: medicated eye drops or surgery.

Glaucoma is several conditions of the eye that damage the optic nerve, which is vital to perfect vision. This damage is caused due to an abnormally high pressure in your eye. Glaucoma is one of the leading causes of blindness in the United States. It can happen at any age but is most common in older adults. If you lose your vision due to glaucoma, it is not possible to gain it back. It is important to get regular eye appointments because if glaucoma is caught early, the loss of vision can be slowed or prevented. There are two types of glaucoma. Open-angle glaucoma and acute angle-closure glaucoma. The symptoms for these two are very different. Open-angle glaucoma symptoms include patchy blind spots in your central or side vision,

Glaucoma occurs when there is an increase of intraocular pressure or IOP; IOP is the pressure of the fluid within the eye that builds up behind the eye (Ignatavicius & Workman, 2013). If the retinal ganglion cells degenerate, the visual field will decrease as well as the optic nerve will atrophy causing a distinctive clinical appearance (Gemenetzi, Yang, & Lotery, 2012). There are several types of glaucoma but the main two types of glaucoma; open-angle and

Glaucoma is an eye disease which causes damage to the optic nerve damage. Consequently this damage can lead to progressive vision loss or blindness if left untreated. The human eye is constantly making aqueous humor which provides sustenance to surrounding tissues. Maintaining a fluid balance requires the fluid leaving the eye through the drainage system which is a meshwork along the outside edge of the iris. However, if too much fluid is being produced or if the drainage system is not working properly, intraocular pressure builds and in turn causes the optic nerve damage and the deterioration of vision. Most people do not realize they have glaucoma until they are diagnosed and already have peripheral field of vision loss. The main treatment for glaucoma is topical eye drops but when a patient is on maximum eye drops and intraocular pressure is not controlled or if they have many

The buildup of fat deposits behind the eyes puts pressure against the optic nerve which may cause blurred, doubled or decreased vision. Exophthalmos can gradually develop over time. The patient and family members may not notice until it becomes advanced. When the eyes become predominant in the overall appearance of the patient is when it’s becomes

These cataracts could have formed due to the smoking which introduces toxins or hypertension from the artery occlusion. As the tight junctions lose their structure from the atherosclerosis and the toxins within the blood, they allow in insoluble proteins with disulfide bonds which results in different size and weight structures decreasing the uniformity within the lens (Shambhu and Diwan 1984). The main flaw to this causation would be the singularity in that both oculus unitas would have cataracts in most cases, hence the cataract must be mostly onset by the ocular ischemic

A 6-year-old male underwent an initial eye examination for evaluation of hyperpigmentation of both eyes at 1 year of age. He was diagnosed with benign conjunctival melanosis. He was also diagnosed with an increased cup-to-disc ratio and mildly elevated intraocular pressures in each eye. Intraocular pressure was maintained in the mid-teens bilaterally on topical glaucoma monotherapy. At 4 years of age, he relocated. When he was 5-years-old, he underwent bilateral glaucoma shunt placement elsewhere The operative reports and glaucoma drainage implant (GDI) specifics were not obtainable. No prior or subsequent ocular surgeries were performed. He returned to our care after 2 years. His eye pressures were controlled without glaucoma medications. There were GDIs in the superotemporal quadrant of each eye. In the right eye, there was corneal edema in the superotemporal quadrant extending to the pupillary margin and a 3 millimeter central subcapsular cataract. The shunt tube extended into the anterior chamber approximately 2 millimeters (Figure 1A). The anterior portion of the tube retracted posterior and was barely visible in the anterior chamber with adduction of the eye (Figure 1B). Upon abduction, the tip of the tube travelled up to 6 mm towards the 4:00 position (Figure 2A) (Video). Intermittently, the tip of the tube would dive posterior to the iris at the 4:00 position to touch the lens (Figure 2B).

The symptoms associated with glaucoma are unfortunately only realised during the later stages of

As mentioned previously, glaucoma will usually occur due to the pressure rising within the eye. This can happen due to the fluid within the eye not circulating properly in the front of the eye. This fluid, known as the aqueous humor, will flow out from the eye through a mesh like channel. If the mesh like channel becomes blocked however, the fluid will build up and this will lead to glaucoma. The direct cause of this particular blockage isn’t yet known, although some doctors do believe that inheritance plays a big role. Other less common causes of this condition include blunt or chemical injuries to the eye along with inflammatory conditions. Glaucoma will usually occur in both eyes however it’s not unheard of to involve just one eye or even both but to differing extents. There are also a few factors that could put you at a heightened risk, making you more susceptible and these include:

Pain can be another result of the disease and is affiliated with the height of the intraocular pressure and the velocity with which it rises to that level (Hoskins & Kass, 1989). Altered vision is also a possible result of this disease and occurs in many forms. Episodic blurring of vision is frequently arises when rapid increase of intraocular pressure causes corneal edema. Loss of Snellen visual acuity generally appears late in the sequence of glaucoma unless some other problems transpire, such as central retinal vein occlusion. Other symptoms may include things such as a change in the appearance of the eye, halo vision, and redness. Before other symptoms occur, an increased level of intraocular pressure is usually observed. These symptoms and an increase in intraocular pressure are likely to occur in both open-angle glaucoma and angle-closure glaucoma, which are two of the major types of glaucoma.

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.

Every day you come into contact with millions of disease infused microorganisms that could potentially bring harm to our bodies, but thanks to our amazing immune system, most of those diseases are destroyed before we develop symptoms. However, some of those microorganisms escape the wrath of our immune system and precede to harm our body. One of the diseases caused from microorganisms such as “Staphylococcus aureus, Streptococcus pneumonia, or Haemophilus” (NIH), can cause conjunctivitis. The more commonly known term for conjunctivitis is pink eye, which is the inflammation of the conjunctiva or outer layer of the eye.
