Glaucoma Is Not A Specific Disease

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

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,

For each patient, the automated visual field tests were obtained by Humphrey Field Analyzer and optic disc images by Topcon fundus camera. Horizontal and vertical cup-to-disc ratios were calculated by a manual, planimetric technique. Mean deviation (MD) and pattern standard deviations (PSD) were documented.

The first disease I’m going to mention is Glaucoma, according to Web MD last updated in 2015, Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life.

Currently, the pathogenesis responsible for glaucoma is not well understood. It has been suggested that local ischemia or mechanical damage from a raised intraocular pressure (IOP) resulting in retinal ganglion cell (RGC) loss may have a role in its aetiology. The treatment for glaucoma aims to reduce IOP through therapeutic or surgical means to reduce glaucomatous progression. The first line of treatment involves topical therapy such as eye drops. There are many classes of anti-glaucoma drops with prostaglandin analogues being the most potent ocular hypotensive with a good safety profile.

71.3 ± 13.5 for NTG, P-value < 0.005).11 However, all these imaging studies evaluated RNFL thickness for POAG and NTG patients but not for secondary types of OAG such as pseudoexfoliation glaucoma (PXG) and pigmentary glaucoma (PDG).

These characteristics of the glaucoma patient can progress to blindness. Regularly, glaucoma and its treatment have been closely connected with intraocular pressure. In normal tension glaucoma, damage to the optic nerve occurs without any increase in intraocular pressure. Normal tension glaucoma most often occurs in the elderly and can lead to loss of sight and significant disability. Numerous studies indicate that glaucoma patients have altered retinal circulation. Extensive morphological studies describe endothelial proliferations in the retinal vessels of glaucoma patients. [Charlson2011] In study [Evans1999] Evans et al. assert that glaucoma patients demonstrate faulty autoregulation in the retina during posture change: their CRA response to posture variation shows no change. The CRA directly feeds and is the only source of blood supply for the retinal arteries. These distal vessels nourish the retinal ganglion cells and the confluence of unmyelinated nerve fibers anterior to the lamina

Visual acuity is a screening procedure that is concentrated on the diagnosis of an illness and measures visual acuity. This procedure is often done by the medical assistant in a well-light area or room. “The medical assistant should observe the patient to look for any condition or behavior that could possibly indicate visual distance, such as tilting the head forward or to the side, excessive blinking or eyes watering, frowning or puckering the face, closing of one’s eyes when testing both of the eyes and signs of straining to see. Common devices used to measure distant vision is a Snellen chart. This chart will show the distance an individual can read the chart from. For an individual with reading troubles a chart with letter E’s arranged

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

An optometrist is a registered, independent, health care provider that specializes in the examination, diagnosis, treatment, management and prevention of diseases and disorders of the human visual system and its’ associated structures. The primary task of an optometrist is to perform regular eye examinations, but an optometrist might also prescribe glasses and contact lenses, rehabilitate the visually impaired, diagnose and treat ocular diseases, perform comprehensive examinations of both the internal and external structures of the eye, evaluate patients’ vision and determine appropriate treatments, treat clarity problems or eye diseases such as glaucoma and ulcers, and diagnose complications due to the aging process, accidents,

In this work, all the eyes had IOP above 21mmHg on maximally tolerated anti-glaucoma medications. The mean preoperative IOP was insignificantly different between the ologen group and MMC, while mean postoperative IOP was significantly lower in the MMC group on the first postoperative day (p=0.007), and at 1 week (p=0.039). At 1, 3 and 6 months, there was no significant difference between both groups, while 1 year postoperatively it was significantly lower in the ologen group (p=0.005). And there was a significant drop in mean IOP at each follow up period in each group (p<0.001).

Glaucoma is classified as either open angle or closed angle , and both of these different signs. Many individuals who have open-angle glaucoma don’t experience any visible signs in the beginning which necessitates consistent eye tests, so that your eye doctor can be able to notice problems at an early stage.

Early detection, through regular and complete eye examination, is the key to protect vision from damage caused by glaucoma.The eye examination includes:

In this research study, we used AS-OCT measurements from a study in a South Indian Population9 to determine the characteristics and dimensions of anterior segment parameters with an aim to determine the biometric parameters of the eye that differ most across sibling groups. We hypothesize that anterior segment parameters measured in siblings of patients with primary angle closure differ from those measured in siblings of patients with open

In modern ophthalmology, detection of optic disk is a very important step for retinal image analysis. It is one of the main feature of extracting the anatomical structure of the retina as illustrated in Fig. 1(a). Optic disk can be defined as the circular brighter region in retinal fundus image where blood vessels converge and optic nerve is formed. OD detection is very indispensable for the computer aided diagnosis of different eye diseases such as glaucoma detection and diabetic retinopathy [1]. Fig. 1(b) represents the fundus image with retinal lesion.
