Pseudo Myopi The Refractive Anomaly Of The Eye

The records have been reviewed. The member is an adult male with a birth date of 05/16/1973. He has a diagnosis of bilateral degenerative myopia. His treating provider, Amy Camarota, OD, recommended treatment options on 03/18/2016, one of which was scleral lenses, which the member opted and paid for on 04/01/2016.

Myopia - is the refractive condition where the farthest point of focus is located at a point near to the observer, and not at infinity. When one is nearsighted, distance vision is blurred at all times while near vision is often excellent within a certain range. There are a number of explanations for this optical condition. The eyeball may be too long, causing the image to be focused short of the retina at the back of the eye. Or, the focusing lenses of the eye are too strong.

Visual impairment is a state wherein an individual experiences difficulty in seeing or not being able to see anything physical presented to them. According to Mandal, MD (2013) It is a state where a visually impaired person’s eyesight cannot be corrected back to a “normal level”. Visual impairment is often associated with old age. In Europe, an estimated 15.5 million people have visual impairment and in seven countries in Europe, about 50% of blindness is caused by age-related macular degeneration. (Dibb,

Pain can be another result of the disease and is affiliated with the height of the intraocular pressure and the velocity with which it rises to that level (Hoskins & Kass, 1989). Altered vision is also a possible result of this disease and occurs in many forms. Episodic blurring of vision is frequently arises when rapid increase of intraocular pressure causes corneal edema. Loss of Snellen visual acuity generally appears late in the sequence of glaucoma unless some other problems transpire, such as central retinal vein occlusion. Other symptoms may include things such as a change in the appearance of the eye, halo vision, and redness. Before other symptoms occur, an increased level of intraocular pressure is usually observed. These symptoms and an increase in intraocular pressure are likely to occur in both open-angle glaucoma and angle-closure glaucoma, which are two of the major types of glaucoma.

Amaurosis fugax is a condition in which you lose your sight in one eye. The loss of vision in the affected eye may be total or partial. It usually lasts just a few seconds or minutes. Then, it returns to normal. Occasionally, it may last for several hours. This is caused by interruption of blood flow to the artery that supplies blood to the part of your eye that contains the nerves needed for sight (retina).

Growing up, I was witness to an uncle of mine who progressively lost his eyesight. I saw a perfectly healthy man, slowly being plunged into a world of darkness. It was difficult to understand how someone could lose their eyesight and with it lose so much more. As I grew older, I learnt his vision loss, which had caused permanent blindness, was due to a condition called Glaucoma. Being a victim of a curious mind, I tried to research and understand this condition which affects the eye. It was then when that spark of interest in the anatomy of the human eye and the conditions and many pathologies which affect it, arose inside of me.

Do you know what the leading cause of blindness is in Americans from ages 20 to 74? It is diabetes an illness that changes the way the body breaks down and absorbs sugars. These changes, doctors feel, take away oxygen that the retina needs. (The retina is the back layer of the eye and it is where sharp images are formed.) When this happens’ some small blood vessels may become weak and break, vision problems occur when this blood leaks into the areas around the retina. Diabetes can also cause glaucoma and cataracts. Glaucoma is a disease that causes a lot of pressure in the eye because too much fluid builds up. Cataracts, on the other hand, cloud the lens of the eye and this makes a person feel like he or she is looking through a grimy window.

The most common cause for Amblyopia is the misalignment of the eye. When both of your eyes do not align in the same direction the brain turns off the vision to the misaligned eye, and then your brain only uses the eye that is aligned. If this continues the eye will not connect to the visual cortex properly and Amblyopia will occur.

Anisometropia causes blurred vision usually in one eye inhibiting normal visual perception and thus causing disparate visual input to the cortex Tailor et al., (2016). Clinically anismetropia is

A 37 year old man presented with insidious onset painless progressive diminution of vision in his right eye of 05 months duration. There was no associated history of prior ocular disease, ocular trauma or any systemic illness. His decimal best corrected visual acuity (BCVA) was 0.05 OD and 1.0 OS. On retinoscopy simple hypermetropia of +1.25 DS OD and +1.50 DS OS was noted. Anterior segment examination

Since myopia is when the eye’s depth is longer than usual, the focal lenth is shorter. When the focal length is shorter, the image is formed in front of the retina and what the person sees is a blurry image as shown in the top

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.

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

The eyelids are made up of four layers, the skin, muscle, connective tissue and conjunctiva. The process of vision occurs when light waves from an object, enter through the iris. Light then passes through the lens of the eye, a double convex structure that is used to focus the light, and then reaches the retina. Inside the retina are rods and cones. Rods are used to sense light and dark, and cones are used for sensing colors. Whether the light entering the eye hits the cones or rods, a signal is sent across the optic nerve to the brain where it is processed and viewed as an image. Some issues people have with eyesight are as follows. Those who are farsighted are unable to see things clearly at a short distance, compared to a long distance. This occurs when the light that enters the eye is focused behind the retina, and not directly onto it. When the cornea is not curved enough, this happens. Nearsightedness is when one can see objects clear at a short distance, but not at a longer distance, and this is often caused by a change in the cornea. A Blind spot is the location the optic disk, where the optic nerve fiber exits, and at this location there are no cones or rods, so there is a blind spot.

A camera lens focuses patterns of light onto film which records the image exactly. If the lens is out of focus or partially covered, a b lurry or obscured picture will result. The film is a recording device, it does not interpret and select what it portrays. Images from a camera are objective in a very literal sense. Seeing, however, is not such a seamless process. Our eyes work similarly to a camera in that they have a lens which focuses a real image on our retina, a light sensitive sheet of cells. This retinal image is a portrayal of the world as it truly is. The image which we see, however, is not this image. By considering a normal vis ual property as well as an uncommon ocular disorder the process of formulating our
