The prevalence of glaucoma increases with age. {{configCtrl2.info.metaDescription}} This site uses cookies. | PowerPoint PPT presentation | free to view Glaucoma is a condition where an accumulation of fluid in the eye increases the intraocular pressure resulting in optic nerve damage. United States. Frequency. Glaucoma in eye may be defined as a group of diseases characterized by a triad of optic neuropathy, raised intraocular pressure (IOP), and a specific pattern of visual field defect. Symptoms of acute angle-closure glaucoma severe eye pain, nausea and vomiting, headache, blurred vision and/or seeing haloes around lights, profuse tearing. The pathophysiology of glaucoma is not completely understood, but relates to retinal ganglion cell death. 2008 Apr-May. Symptoms are a result of visual field loss. A genetic etiology has also been considered as an explanation for the condition. Axenfeld-Rieger syndrome(ARS) refers to an autosomal dominant genetic condition characterized by anterior segment dysgenesis and systemic abnormalities. Corneal abrasion 5. Early-onset glaucoma can have different inheritance patterns. The modern classification of childhood glaucoma began with the term buphthalmos, or ox-eyed, which was used to describe the secondary effect of elevated intraocular pressure (IOP) on the elastic infantile eye. Any damage to the optic nerve therefore prevents those signals from reaching your brain, which results in sight loss. This damage is often caused by an abnormally high pressure in your eye. The normal draining process of the aqueous humor therefore is disrupted, which causes a rise in intraocular pressure (IOP). How the courts address or respect our rights as citizens. If left untreated, most types of glaucoma progress, without warning or obvious symptoms to the patient, towards gradually worsening visual damage and could eventually lead to blindness. 66 million people are worldwide affected by the glaucoma. Diabetes also increases the risk of other serious vision conditions, such as cataracts and glaucoma. Normal IOP is 19 – 21 inches of mercury. In glaucoma, the optic nerve of the eye is damaged, which leads to irreversible blindness. Damage from the pressure causes loss of peripheral vision, and eventually, blindness. ... Dr. Reckeweg R40 Drops is also beneficial for lack of red blood cells (pernicious anemia), leukemia, anemia, and ... Phaseolus nanus: Sugar in urine, irregular cardiac action.

Glaucoma can develop in one or both eyes. The glaucoma is typically classified is as open angle or closed angle and as primary or secondary. Pathophysiology for Glaucoma • Damages the optic nerve resulting in loss of vision & blindness in serve cases • 5 types: 1) Primary open-angle glaucoma=most common form; no symptoms or early signs 2) Angle-closure glaucoma=acute glaucoma or narrow-angle glaucoma; eye pressure rises quickly; rare Medical emergency; headaches, eye pain, nausea, rainbow around lights at … The fluid drains out through an area called the drainage angle.This process keeps pressure in the eye (called intraocular pressure or IOP) stable. This loss may be acute or episodic, or … Hyphema is the collection of red blood cells in the anterior chamber. Glaucoma is a condition where an accumulation of fluid in the eye increases the intraocular pressure resulting in optic nerve damage. Overview of Glaucoma. Importance: Glaucoma is a worldwide leading cause of irreversible vision loss. It is this raised pressure that compresses and damages the optic nerve. Informational Powerpoint on Glaucoma Author: newinfo Keywords: Glaucoma, causes of glaucoma, risk for glaucoma, symptoms of glaucoma, detect glaucoma, treatment of glaucoma, eye pressure, primary open-angle glaucoma Last modified by: … Glaucoma VF Defect (HODAPP, ET AL, 1993) 2. Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. If left untreated, most types of glaucoma progress, without warning or obvious symptoms to the patient, towards gradually worsening visual damage and could eventually lead to blindness. Glaucoma is a group of eye diseases that cause progressive damage of the optic nerve at the point where it leaves the eye to carry visual information to the brain. Angle-closure glaucoma 3. The optic nerve carries signals from the eye to brain and allows you to see. View this sample Outline. It's often linked to a buildup of pressure inside your eye. Most cited articles. Pigmentary glaucoma is caused by pigment dispersion syndrome, an autosomal dominant disorder characterized by pigment liberation from the iris epithelium. CLUSTER OF 3 OR MORE NON-EDGE POINTS (in a typical location for glaucoma), ALL OF WHICH ARE IDENTIFIED AS SIGNIFICANT, WITH AT LEAST ONE AT THE p<1% ON TWO CONSECUTIVE TESTS • (ON 24-2, USE ALL POINTS)-OR-Minimum Criteria for Diagnosis of Glaucoma VF Defect (HODAPP, ET AL, 1993) 3. Origins of Pain in the Head • Extra-cranial pain sensitive structures: – – – – – – – Sinuses Eyes/orbits Ears Teeth TMJ Blood vessels 5,7,9,10 cranial nerves carry pain from thes strucure • Intra-cranial pain sensitive structures: – Arteries of circle of willis and proximal dural arteries, – Dural Venous sinuses,veins – Meninges – Dura Glaucoma, the second leading cause of blindness, is characterized by changes in the optic disc and visual field defects. NCP for Hypoglycemia - Nursing Diagnosis and … Glaucoma Diagnosis Gap in India highlights, about 1.2 million have been rendered blind and at least 12 million are affected. 10. Glaucoma Tests: Visual Acuity A refraction is done to determine best corrected vision. 73. Undergrad. Secondary glaucoma refers to any form of glaucoma in which there is an identifiable cause of increased eye pressure, resulting in optic nerve damage and vision loss. Pathophysiology of Glaucoma – Glaucoma is “a disease of the eye in which fluid pressure within the eye rises - if left untreated the patient may lose vision, and even become blind.
