Cataracts And Glaucoma Research Paper

The Ophthalmologist will decide if a laser treatment is appropriate for the patient on its own or alongside topical therapy. There are different types of laser treatments depending on what type of glaucoma that can be done to help lower the pressure in the eye. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation (OPT119). Lasers produce a highly concentrated beam of light that can make a very small burn or opening in the eye tissue, based on the strength of the light beam resulting in drainage of aqueous humor and releasing the pressure in the eye (5). The initial procedure starts with putting freezing drops in the eye and the patient placing the chin and forehead on a special microscope called a slit lamp. A special lens is then placed in front of the eye which helps prevent blinking and guides the highly fixed beam of light. The types of lasers are Laser Trabeculoplasty – Selective Laser Trabeculoplasty (SLT) and Argon Laser Trabeculoplasty (ALT), Laser Peripheral Irdotomy (LPI), and

Cataract is a medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision. It si a common condition in people older than 40 and it is the primary cause of blindness in the world.

Glaucoma is due to excessive eye fluid, which accumulated intraocular pressure. Acute Glaucoma can lead to blindness, within a few hours. For early onset glaucoma, your Vet can prescribe eye drops that decrease the pressure or recommend surgical

A cataract is a clouding of the lens of the eyes, causing the vision to be blurry. It is caused by protein clumping together in the lens forming a small clouded area; even though it isn’t painful within time, it can grow larger making it harder to see. It is commonly found in older people. It can occur in either or both eyes; however cannot spread from one eye to another. In age-related cataract can affect your vision in two ways—clumps of protein or lens slowly colors with age.

This case study follows a 63-year-old Caucasian man with a 55-year history of long-standing retinal detachment after trauma. He came into their facility and presented pain and redness, a total hyphema, no light perception vision and an intraocular pressure of 60 mmHg (right eye). He disclosed that he has a history of diabetes and coronary artery disease. He also stated he was hit in the eye with a stone 55 years ago. Following anterior chamber washout, he was found to have neovascular glaucoma. After washout and intraocular pressure control, his visual acuity improved to light perception. He underwent vitrectomy, membrane peeling, endolaser and silicone oil placement to reattach his retina, and then a second retinal reattachment procedure Following

Glaucoma is an ocular disorder which results in fluid pressurization in the front of the eye, thereby damaging the optic nerve, which is responsible for transmitting visual information to the brain.

Your vision. Many people experience clear vision shortly after cataract surgery - but, everyone heals differently. Your vision may seem cloudy or blurry when you first remove the protective shield. Your eye needs to adapt to the new intraocular lens that replaced your natural lens. You may even see some wavy distortions to your vision - again, this is a normal reaction.

A cataract is a obscuring of the lens in the eye that affects the power of vision. Mostly cataract are associated with ageing. Cataracts are very common in older people. It can arise either in both eyes and one eye. It is not communicative, hence it cannot be transmitted from one eye to other.

Ancient Ophthamologist’s failed to understand many of the common eye conditions that are very prevalent in modern Ophthamotry. Many of the conditions of the eye that were

Cataract is known as a build-up of protein clouding the eye lens which distorts or blocks the light entering the eye. When new lens cells form on the outside of the lens, all older cells are compacted into the center of the lens which therefore causes Cataract. Cataract can be partial or complete, stationary or progressive, hard or soft. There are 3 types of cataract known as Nuclear Sclerosis, Cortical Cataracts, Posterior Subcapsular cataracts. But the most common type of cataract is Nuclear sclerosis. Which involves in the central part of the lens. Sclerotic is due to the condensation of the lens nucleus which deposition of brown pigment within the lens. Cataract can be first presenting during birth or early childhood which is a result of hereditary enzymes defect. At first cataract can be very undetectable, but later it will grow and you will have exhibiting

A cataract is defined as an opacity of the lens of the eye that causes partial or total blindness. The word is derived from the Latin "cataracta", which means "waterfall.” To the eye of an observer, the foamy white opacity of an advanced cataract resembles that of the turbulent water of a waterfall. (Chang, Cataracts Definition, 2014)

Glaucoma is the name given to a group of eye diseases that causes damage to the optic nerve fibers and can lead to progressive vision loss or blindness if left untreated. The damage is primarily a result of the buildup of intraocular pressure, which results when an imbalance occurs in the production and drainage of aqueous humour. However, some glaucoma is not distinguished by high intraocular pressure but as optic nerve damage. In the human eye the ciliary body constantly creates aqueous humour to provide sustenance for surrounding tissues. To maintain a healthy balance as new fluid is produced, older fluid must leave the eye through the meshwork drainage system along the periphery of the iris. If too much aqueous humour is produced or the drainage system is not working properly consequently intraocular pressure builds, causing optic nerve fiber damage and deterioration of vision.

Cataract is the leading cause of blindness in the world [1] . Cataract is a clouding of the lens in the eye that affects vision [2]. Cataract can occur in either or both eyes. It cannot spread from one eye to the other [2] .Cataracts generally form very slowly. Signs and symptoms of a cataract may include:

If that doesn’t work, then the patient will need to get cataract surgery. The only effective treatment for cataracts is surgery. Cataract surgery involves removing the clouded lens and replacing it with an artificial one. Cataract surgery is generally done on an outpatient basis, which means the patient won't need to stay in a hospital after the surgery. During cataract surgery, the eye doctor uses local anesthesia to numb the area around the eye. You’re normally awake during the surgery. Cataract surgery is generally safe, but there is a risk of infection and bleeding. After the procedure, patients might have some discomfort for a few days. Generally, the lens will be healed within eight weeks. If a patient needs cataract surgery in both eyes, the doctor will schedule surgery to remove the cataract in the second eye a month or so after the first surgery.

glaucoma 3 is a disease that leads to vision loss. This vision loss is due to an increase in intraocular pressure due to a greater secretion rate of aqueous humor than the drainage rate in the chambers in the eye.This increased intraocular pressure builds up in the eye leading to damage of nerve fibers and blood vessels, damaging the optical nerve. the two main types of glaucoma are open angle glaucoma (a slow build up in blockage) and angle closure glaucoma ( rapid/sudden blockage), both are caused by blockage at the trabecular meshwork (location of drainage). The aqueous humor is a transparent gelatin that creates the pressure in the eye of a glaucoma patient, it is used to transport nutritional substances, immunological substances, and is used to give the eye its globe shape. The aqueous humor enters the eye’s posterior chamber through the ciliary body into the posterior chamber (between iris and lense) then goes through the pupil into the anterior chamber (between the iris and the cornea) and drains out through the trabecular meshwork (filter-like tissue).
