Glaucoma

Glaucoma is an eye disorder where there is pressure in the eyeball that can cause loss of vision. The pressure that is created is known as “intraocular pressure”. It mainly affects the optic nerve. If caught early enough, treatment can be done to prevent major vision loss, or for your vision to worsen. Glaucoma cannot only develop just from your drainage system malfunctioning. Babies can have an underdevelopment of the drainage system in their eye, which can be inherited, but is very rare. This…

“ For a better comprehension of Glaucoma For nearly century glaucoma has been considered as one of the most common eye pathologies around the world but also one of the leading causes of blindness .In fact Glaucoma specifically in the united states according to the national institute affects more than three million people.before going further in facts a deeper look about such disease is necessary,an analysis of his origin, the causes and the solutions to the problem are indispensable and…

Glaucoma is an ocular disease which destroys the optic nerves in the eye due to an increase in the intraocular pressure. This disease is the second most common cause of blindness in the world and Canada (Noertjojo et al. 2006), and the most prevalent form of the disease is Primary Open Angle Glaucoma (POAG). It is estimated that by 2020, there will be almost 80 million people in the world with both primary open angle glaucoma (POAG) and angle closure glaucoma (ACG) with POAG more prevalent.…

Open-Angle Glaucoma According to the authors Ramdas, Wolfs, Kiefte-de Jong, Hofman, and de Jong (2013) of the article "Nutrient Intake and Risk of Open-Angle Glaucoma: The Rotterdam Study", Open-Angle Glaucoma is a progressive neurodegenerative disease that leads to glaucomatous optic neuropathy and eventually, through glaucomatous visual field loss, to the loss of sight. It is also the most common cause of irreversible blindness worldwide. Increased intraocular pressure, oxidative stress, and…

Angle-closure glaucoma is defined as an obstruction of the flow of aqueous humor in the eye due to the iris and trabecular meshwork being too close together which creates a closed angle where 270 degrees or more of the angle is occluded.1 Occlusion of the angle causes the intraocular pressure (IOP) to elevate. Optic nerve damage can occur if IOP is greater than 40 mmHg and permanent vision loss can occur if an individual's IOP is greater than 60 mmHg.2 The incidence of angle-closure glaucoma…

INTRODUCTION The lamina cribrosa (LC) within the scleral canal in the optic nerve head (ONH) is thought to be the primary site of axonal insult in glaucoma.1-3 It is of interest in glaucoma to understand the anatomy of the LC and surrounding tissues and how they change with aging and disease. LC has been investigated using a variety of methods, including histologic section,4,5 detergent digestion of surrounding tissues6,7 and finite element modeling.8,9 In human glaucomatous eyes, LC…

Glaucoma, what is glaucoma? If you are like me, you think it has to do with the pressure in your head and that marijuana is the alternative drug that can make it better. I immediately think about the movie “How High” and see the little old lady sitting on her bed with a pipe saying that it helps with glaucoma too. But is any of this true? Yes and no. Glaucoma does not affect the pressure in your head known as intracranial pressure or ICP. What it does affect is the pressure that is put onto the…

Health Organization), glaucoma is a group of diseases that is more commonly seen than people might imagine. It is estimated that over three million Americans have glaucoma, yet only half of that amount are aware that they have it. Glaucoma is a complex disease that leads to irreversible vision loss caused by damage to the optic nerve. The…

Visual acuity Main article: Visual acuity Visual acuity is the eye's ability to detect fine details and is the quantitative measure of the eye's ability to see an in-focus image at a certain distance. The standard definition of normal visual acuity (20/20 or 6/6 vision) is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc. The terms 20/20 and 6/6 are derived from standardized sized objects that can be seen by a "person of normal vision" at the specified…

Americans have glaucoma, making the disease not so uncommon. According to the National Eye Institute, people over the age of 60 are more at risk. Glaucoma even has its own month, National Glaucoma Awareness Month in January. Spreading the word about the vision disease can be an all year event, and you should always ask your eye doctor if you might be at risk. And a 58 percent increase in glaucoma cases is expected by 2030. This increase will impact nearly 4.2 million people. Glaucoma, or the…
