A Better Understanding Of Glaucoma

It’d better we try to think about a closed, sustainable water tank. The more level of water is poured into the tank, the greater the pressure inside it is. Similarly, high pressure inside the eye occurs - the more fluid, the greater the pressure. Moreover, the optic nerve in the eye can be destroyed by overload of the pressure.

Glaucoma is a condition that affects the eyes by causing damage to the optic nerve within the eye and it can worsen over time. It’s generally associated with an increase in pressure inside of the eye. More often than not it’s inherited and may not reveal itself until much later in life. The increase in pressure is known as intraocular pressure and can damage the optic nerve that’s responsible for transmitting images to your brain. Sadly, if you fail to recognise that you’re suffering from glaucoma and neglect to have it treated, then the damage to the optic nerve from high pressure can become permanent resulting in permanent vision loss. Without treatment, glaucoma can and will result in total and irreversible blindness within a

Visual field defects, defects pertaining to everything a person sees from peripheral vision to central vision, and optic disc damage is the basis of diagnosis in glaucoma (Hoskins & Kass, 1989). If the eye pressure is not within the normal range or if the optic nerve looks unusual, doctors may perform a visual field test that maps out a person's field vision, or perform a test to check whether the angle where the iris meets the cornea is opened or closed. The optic nerve and visual field changes of glaucoma

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 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 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 is a disease that damages the optic nerve because of extra fluid increasing pressure in the eye (Boyd). It is also the leading cause of blindness if left untreated in people over sixty Boyd states. Varieties of options are available for treatment regarding glaucoma and all are intended to lower the blood pressure and protect optic nerve (Radhakrishan and Iwach). Glaucoma can be treated with eye drops, pills, and surgery or a combination of these methods. (“Treating Glaucoma”). Right now eye drops are the first choice of treatment because they lower eye pressure, helping fluid drain better or decreasing fluid made by the eye (Radhakrishan and Iwach). As is states in the article “Treating Glaucoma” when eye drops cannot control the glaucoma,

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

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.

Migraine is a complex neurological disease with an undetermined cause. The prevalence of this disease has been reported as 24.4% among the women aged between 30 to 40 years. The prevalence declines by 5% with women aged 60 years and older. Low-tension glaucoma is a type of condition that is observed mainly in those 60 years and older. A higher prevalence of migraine was reported in the 1980s in patients with low-tension glaucoma, and since then, migraine has been considered a potential vascular risk factor for patients with low-tension. This research was performed to see whether patients with migraine show an early sign of cupping, an indication of glaucoma, at an age when the migraine attacks are most frequent. More specifically, the optic

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

The most common visual condition that is affected by this syndrome is glaucoma. 30%-70% of the people who have PWS has glaucoma as well. (Mantelli, 2016). Glaucoma is diseases that damage the eye’s nerve and can result in vision loss. It can be diagnosed at birth, but disease can also develop during childhood and adulthood. Many of the times, the treatment for glaucoma in Sturge-Weber Syndrome is difficult because of the damage that has been done prior diagnosis. There are some surgical procedures that have been developed and most of them are ineffective. Furthermore, seizures occur in about 75 to 90% of patients and typically start by age 1 year old. (McBride, 2016- Merk). Seizures are usually focal but can become generalized. Patient who

Glaucoma is a group of eye disorders that cause blindness by hurting the optic nerve, which is the large nerve that is responsible for vision. In glaucoma, the optic nerve damage is related to a change in the fluid pressure that circulates around the eyeball. In many cases, Glaucoma occurs when the eye's fluid pressure is high, but it can also occur when the pressure is measured as normal.
