Glaucoma

Glaucoma is the leading cause of blindness for people over 60 years old. It is a group of diseases that occur when aqueous humour is unable to flow out of the eye properly, causing an increase in fluid pressure in the eyes, which cause ocular hypertension and damage the optic nerve over time. The flow of aqueous humour can be disrupted either by a partial or full block of its drainage canal or an excess production of the fluid, and the chronic increase in intraocular pressure (IOP) leads to a gradually progressive loss of the visual field and a slow degeneration of the optic nerve (Boyd, 2015). Glaucoma is known to cause widespread loss of retinal ganglion cells (RGCs) over time. As pressure on the optic nerve increases, RGCs are thought to be directly traumatized, which leads to shrinkage and death, and…

Glaucoma is a retinal disease that can lead to vision loss if it remains undetected and untreated. It usually occurs at the optic nerve head region due to the damage of ganglion cells. A study conducted by the Cataract Surgery Registry (CSR) from 2002 to 2012 on patients with pre-existing ocular co-morbidity showed that there has been an increase of around 119 number of patients from year 2011 to 2012 with 1976 and 2095 patients respectively (Mohamad Aziz Salowi & Goh, 2012). Although glaucoma…

Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. The most common type is open-angle glaucoma with less common types including closed-angle glaucoma and normal-tension glaucoma. Open-angle glaucoma develops slowly over time and there is no pain. Side vision may begin to decrease followed by central vision resulting in blindness if not treated. Closed-angle glaucoma can present gradually or suddenly. The sudden presentation may involve severe eye pain,…

Glaucoma is a eye disease that may cause you to be blind or lose an eye. According to visionaware glaucoma is a chemical group of eye disease that can wind to sightlessness by damaging the optic nerve. Here is some story behind glaucoma. Glaucoma has been known in medicine since antiquity. According to nbci Hippocrates described “glaykoseis” as blindness which occur in the elderly . the first person to discover glaucoma and the connection between increased tension of the eyeball was the…

Glaucoma Glaucoma is a condition caused by high pressure inside the eye. The pressure in the eye is raised because fluid (aqueous humor) within the eye cannot get out through the normal drainage system. The increased pressure can cause damage to the nerves of the eye. This can result in loss of vision. It is important to diagnose glaucoma early before damage occurs. Early treatment can often prevent vision loss. There are two main types of glaucoma: • Open-angle glaucoma. This is a chronic…

Glaucoma is a physical aspect of increased pressure on the optic nerve, which transfers to the brain, identifies it. The pressure could cause the damage for a foundation of vision loss. There is no exact know cause of the increased pressure other than genetics, rather than a combination of factors that could lead to early onset or risk for aggressive progression of the disease (Cascella, Strafella, Germani, Novelli, Ricci, Zampatti and Giardina, 2015). There are theories of risk factors that can…

Late presentation of Glaucoma to health facilities is mostly influenced by poor knowledge of the disease, its risk factors and associated consequences. Sources of eye health information is limited and obtained mostly from family members or friends based on past experiences as such, the available information may be inaccurate and influenced by traditional beliefs. In addition, appropriate information is poorly targeted to persons at risk of developing the disease hence, the health and economic…

Intro: More than three million americans have glaucoma according to the Glaucoma Research Foundation. Of that three million only half of them are aware that they have glaucoma. Glaucoma effect so many people yet very few are aware of this chronic disease. Most people would like to see the world and all of its beauty but for many their sight is silently leaving them. Once that vision is lost it can never be brought back. Bringing awareness, knowledge, and understanding to the topic of glaucoma…

Glaucoma is a disease that causes blindness in the eye and it also damages the optic nerve, which is what helps the eye keep its good vision. The optic nerve comes from the sensory fibers and it is what conducts impulses from the retina to the brain. Elderly people are more likely to develop glaucoma when they’re around the age 60 but glaucoma can also develop on young adults, or an infant could just be born with it. 1 out of 10,000 babies are born with glaucoma, which may not seem like a many,…

Primary Congenital Glaucoma Overview- Glaucoma is a disease of the optic nerve. The optic nerve receives nerve impulses from the retina and transmits them to the brain, where it recognizes these electrical signals as vision. Glaucoma is characterized by a particular model of progressive damage to the optic nerve, which usually begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to blindness. Glaucoma is usually, but not always,…
