Causes Of Visua Scotoma

When damage to certain regions of the brain occurs, conditions may develop where one is able to register visual information but incapable to distinguish anything (Anderson, 2009). Consequently, difficulties with visual impairments can include an inability within the brain to interpret and or process visual information (Anderson, 2009). Thus, visual perception impairments or disorders typically refer to the inability to make sense of information received through sight (the eyes) (Weiten, 1998). One such visual perception disorder is visual agnosia.

The main causes of sensory loss in the eye sometimes the delicate cells of the macula become damaged and stop

Ocular Melanoma: two other names for this is called Uveal Melanoma & Choroidal Melanoma. These are said to be the rarest forms of melanoma which can occur in the eyes.

Humans have blind spots because of the optic nerve information that is sent to the brain from the retina is through the optic nerve. Well the nerve has to have a way to exit the eye, that exit is where the blind spot is.

1. Stevens-Johnson syndrome and related conditions such as TEN, chemical and burn injuries to the eye, ocular pemphigoid, or aniridia.

Now that I showed you what I know about scotomas. I will now talk to you about where I have had an experience where my scotoma’s may have

First of all, it is necessary to understand some of the important features of this syndrome (Naeye,

is a disease that causes optic nerve damage resulting in the gradual loss of sight. Currently, it is estimated more than 3 million

Swelling of the optic disk, usually caused by increased intracranial pressure; also called choked disk.

The first disease I’m going to mention is Glaucoma, according to Web MD last updated in 2015, Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life.

A scotoma is a dim or totally black area in your field of vision. There are often areas around the dim or black spot that have normal vision. The scotoma may be in the center of your field of vision or off to the side. A scotoma can occur in one or both eyes.

     Really the cause of Macular Degeneration is unknown. Recently researchers have discovered that a group of genes called ABCR contribute to the disease. When someone has these genes the likeliness of this person to form Macular Degeneration increases by 30 percent. In most situations Macular Degeneration is

Glaucoma is a group of eye disorders that cause blindness by hurting the optic nerve, which is the large nerve that is responsible for vision. In glaucoma, the optic nerve damage is related to a change in the fluid pressure that circulates around the eyeball. In many cases, Glaucoma occurs when the eye's fluid pressure is high, but it can also occur when the pressure is measured as normal.

One cause of strabismus is the inadequate coordination of the six muscles which operate to move the eye. Other less common forms of strabismus result from defective refraction, damaged nerves which connect the photoreceptors to the brain, and damage to the nerves which control the eye muscles.(4) These multiple disorders all have the same effect, presenting conflicting, amblyopic, images to the brain.

“Pay close attention to each student’s individual needs; provide a curriculum similar to that for sighted students; and expect students to integrate into their communities.” (Hall, 2012). There are many different categories of visual impairments that individuals can fall under. People can have low vision, visual acuity, or total blindness along with others. Visual impairment comes in two ways. Friend (2018) claims “Congenital visual impairment refers to a condition that is present at or near the time of birth. An adventitious visual impairment is a condition that is acquired at birth, either in childhood or at some later point in life.” (P. 359). According to Friend (2018), “Visual impairments result when problems exist in the structure or functioning of the eye, when the eye is damaged through illness of injury, or when a neurological problem prevents communication between the brain and the eye.” (P. 360). Friend (2018) found “Retrolental fibroplasia (RFL) is the condition where too much oxygen is placed in the premature incubator where babies are given uncontrolled amounts of oxygen to assist their breathing.” (P. 357). Stevie Wonder became blind through this particular situation. Visual impairment has been around for centuries, but just as the world advances so does the knowledge of visual impairment.
