Glaucoma Research Paper

I am indecisive on what occupation I would like to pursue in. I have many ideas on what I would like to become. Optometrist, optometrist assistant, something to do with law, forensic scientist, or becoming a business owner are my main top occupations I consider. For now, an occupation I would consider and enjoy is to become an optometrist or an optometrist assistant. I’ve always been fascinated by the nervous system, particularly with the optic nerves. I want to help people who aren’t able to see clearly or help them with any problem they have with their eyes. I have glaucoma and I tested for the disease for a year until I was officially diagnosed. There are two types of Glaucoma, Open-angle glaucoma, which is what I have is the type where

The dry form is broken down into three stages; Early, Intermediate, and Advanced (National Eye Institute 3). In the Early stage, people have several small or few medium yellow deposits under the retina called drusen. This stage shows no symptoms or vision loss. During the second stage, Intermediate, more medium or even large deposits happen. As this happens, a blurred spot can develop and more light could be needed for reading. Lastly, in the Advanced stage, a breakdown of light-sensitive cells and tissue causes the blurred spot to enlarge and darken. In this latter stage, facial recognition is unlikely unless the person is extremely close. Either form of Macular Degeneration can only be detected by thorough eye exams. The exam should include visual acuity, which measures sight at varied distance intervals. Also, dilation of the eyes will allow an ophthalmologist to check the retina and optic nerve. An instrument called a Tonometer will measure pressure within the eyes (National Eye Institute 6).

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

It's important to schedule regular eye exams as you age to make sure you don't lose your vision due to glaucoma. Glaucoma is a gradual increase in the pressure inside your eye. Glaucoma starts with no symptoms, but it can ultimately cause loss of peripheral vision and blindness if left untreated. Treatment is typically a simple matter of eye drops and the glaucoma test takes only seconds to preform. It is estimated that half of the people with glaucoma don't know they have it. Make sure you're not one of them.

This article discussed the eye disease, Glaucoma. There are two types of Glaucoma; open-angle and closed-angle. Open-angle Glaucoma there are no visual abnormalities, but there is a mechanical obstruction interfering with the drainage pathway. While closed-angle Glaucoma is a physical obstruction. Signs and symptoms of Glaucoma are; headache, nausea, vomiting, blurred vision, halo vision, and eye pain. Glaucoma progresses slowly and is asymptomatic at first. As the disease progresses symptoms appear, if symptoms are present then there is already irreversible damage to the eye. There is no cure for Glaucoma, treatment is aimed at slowing the progression of the disease. Diagnostic tests done to detect Glaucoma are; measuring IOP, evaluation of

Laser surgery for glaucoma. Laser surgery for glaucoma slightly increases the outflow of the fluid from the eye in open-angle glaucoma or eliminates fluid blockage in angle-closure glaucoma.

In these cases, the angle between the iris and the cornea is too small, which results in the build up of aqueous fluid pressure that pushes the iris forward blocking the trabecular meshwork causing increased intraocular pressures. LPI helps open up the angle to increase fluid outflow and lower the pressure. For patients with narrow angle glaucoma this is also a preventative measure to stop the development of acute narrow angle glaucoma attacks, which present with pain, high intraocular pressure and loss of vision within a couple of days if left untreated. During LPI a a very minute hole is made with the laser beam in the superior periphery of the iris the coloured part of the eye. This helps open up the narrow angle so the aqueous humor can flow forward through the new hole (Chen 2003). The end result is re-balancing the pressure between the posterior and anterior chambers and letting the iris go back to a more plantar position that takes pressure off the trabecular

The eye plays an essential role in the human body. Being able to see and perceive objects by an individual lies fairly on the judgment of the eyes. Cataracts are painless and gradual whereas glaucoma can either be slow and subtle or quick and painful. A cataract is highly likely to result in cloudiness in the eye since light is prevented from entering it correctly (Tzu et al., 2015). According to Jensen (2015), glaucoma leads to a buildup of pressure in the eye, the resultant effect is usually a damaged optic nerve, and has the potential of causing permanent blindness. For a patient battling with diabetes mellitus, they are highly likely to develop diabetic retinopathy. This condition is usually shown by ocular hemorrhages, increased vascular

An estimated three million Americans suffer from Glaucoma. Unfortunately, half of the three millions are still unaware of it. Glaucoma is also the main cause of elder’s

How are they detected? There are three primary ways these are detected. A test of overall visual acuity—the classic reading of the eye chart—will give some idea of cataracts presence. In addition, the dilated eye exam, in which your lens is dilated, will allow the optometrist to take a closer look, and a measure of internal pressure—called tonometry—will provide a full

Eye tests usually consist of visual acuity test, which includes Snellen chart reading ( (you are supposed to read letters of different sizes, from largest in the top to smallest in the bottom line). Afterwards, more profound tests are performed, so that problem’s severity can be thoroughly observed. In accordance with results, corrective lenses will be prescribed. During eye testing, optometrist will be evaluating all three aspects of your

It is known to damage the retina and can most often lead to blind spots and/or temporarily cause a detachment [1]. It can also lead to recurring problems, which can result in cystoid retinal degeneration, leaks from the choroidal hemangioma, as well as suffer from loss of vision [18]. Since this type of treatment involves the use of thin and narrow lasers, there can be malfunctions when trying to reach the tissue vessels. This most likely causes the peripheral view of the patient to become discrete [23]. However, it is an effective treatment that is used in third world countries because of its management, cost efficiency, and material usage [5] [6]. Furthermore, it can be effective when using this type of treatment because of the low side effects. Since it is a bloodless procedure, photocoagulation causes less physical pain and an easier method to avoid having a contact with any type of infection. It also makes it easier for the patient to have a much quicker recovering period, because it can be tolerated by children, young adults, as well as the much older generation

Clinical optometrists take on the task of routinely evaluating and dealing with patients on a daily basis while also attempting to maintain a healthy, successful business environment. The book Clinical Procedures for Ocular Evaluation describes how clinical optometrists maintain healthy relationships with patients and also detail different tests that are commonly implemented. These tests allow for doctors to determine a patient’s well-being and follow the necessary steps to improve the state of their eyes. Clinical Procedures for Ocular Examination is a viable tool that can be used to manage a patient’s complaints and general health history, and assess which phases of examination and problem-specific testing should be implemented.

“Ocular hypertension is a condition where the intra-ocular pressure is above normal range of ten through twenty-one millimeters Hg. Topical and oral corticosteroids may also increase intra-ocular pressure, particularly in those patients with genetic predispositions to glaucoma. Thorough medical history is needed to make appropriate decisions for treating glaucoma (Lee and Higginbotham 692).

here are three categories that are included in the examination of a myopic patient: “refractive examination, binocular examination and ocular health examination” (Grosvenor & Goss, 1999). Refractive examination: Keratometry, this assessment tests for possible astigmatism which may be overlooked due to narrow pupils, squinting or poor responses from the patient and lastly retinoscopy, this test involves the examiner shining a light at the patient’s eye while the patient is fixated at the letter chart or at another object in the distant, this tests how well the eye responds to the changes in condition (Grosvenor & Goss, 1999). Binocular examination: Cover test which tests for phoria or tropia, involves the covering of the eyes alternatively and
