Glaucoma And Closed Angle Glaucoma

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

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.

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

Differential diagnoses : -Giant Cell Arteritis (GCA), myasthenia gravis, thyroid eye disease, chronic progressive external ophthalmoplegia, internuclear ophthalmoplegia,skew deviation, parinaud syndrome, idiopathic orbital inflammatory syndrome. 4 Danger and referral: complete pupil involving/relative pupil involving CN3 palsy is an emergency and mass or aneurysm needs to be ruled out as it can be fatal. 4, Hence refer immediately to neurologist for CNS imaging.4 This also applies to patients with pupil sparing palsies who are younger than 50 (unless long term diabetes/hypertension) or with progression/additional CN/neurologic defects or with incomplete palsies as this may turn into a pupil involving palsy (closely monitor

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).

This depends on how early or late patients are willing to receive a diagnosis from ophthalmologists. In early treatments, glaucoma is not curable, but there are methods to control its progression or to prevent the increased risk of blindness. What ophthalmologists aim for in treating this disease is decreasing intraocular pressure in one’s eye. Determined by the condition the patients are in, “options may include eye drops, laser treatment, or surgery.” The Prevent Blindness America Organization plays an extensive role in projecting awareness for glaucoma and in helping those to fight against it. They “conduct mass glaucoma screenings” and list possible medications such as beta-blockers and carbonic anhydrase inhibitors. These are used to decrease the quantity of aqueous fluid in the eye (Marks and Montauredes

The most frequent ocular complications reported for all the AVM groups, are: vascular occlusions, aneurysm formation, intraretinal haemorrhage, exudation and cystoid macular oedema. Furthermore, neovascular glaucoma and open angle glaucoma have been described as a result of a retinal central vein occlusion [1].

Glaucoma is a condition having to do with the buildup of pressure within the eyeball due to the obstruction of the outflow of liquid in the eye. Intraocular pressure can damage the optic nerve, which transmits images to the brain. If destruction to the optic nerve from high eye pressure continues, glaucoma will cause eternal loss of vision. The less common cause of glaucoma include a blunt natural damage to the eye, strict eye infection, obstruction of blood vessels in the eye, seditious conditions of the eye and occasionally eye surgery to correct the condition.

Some people who are at higher risk or developing glaucoma are, Mexican Americans, African Americans over the age of 40 and anyone over the age of 60. A good way to check if you are at risk is to visit the eye doctor and have them perform a comprehensive dilated eye exam. The optometrists will often perform tests such as visual acuity tests, this checks how far one can see. A visual field test is also performed which tests ones peripheral vision. the optometrists also do a tonometry test which is an assessment on eye pressure which is particularly important in detecting glaucoma. They can check the thickness of ones cornea through a test called pachymetry. Most doctors prescribe specific eye drops to those who are at high risk of developing glaucoma, these drops usually reduce the chance of developing glaucoma by about

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

The first, and more common is open-angle glaucoma. What causes open-angle glaucoma is the tissue that drains liquid from the eye becomes blocked to where the fluid cannot be drained which then increases your eye pressure. Doctors still don’t know what causes this blockage, but they have found that it can be inherited. This increased eye pressure then leads to

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

Furthermore, a research conducted by Harizman et al. (2006) suggested that the inferior, superior, nasal and temporal (ISNT) rule is a helpful method in the diagnosis of glaucoma and risk evaluation during practice. Based on this rule, it is thought that the inferior rim is always thicker than the superior rim followed by nasal rim and lastly the temporal rim is the thinnest (Bourne, 2006).

Elevated internal eye pressures – if the intraocular pressure is higher than normal then you’ll find yourself at an increased risk of developing glaucoma.

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.
