Scotoma

The Visions of Hildegard: Scotomas and Phosphenes Oliver Sacks (2007) discussed a case study concerning Hildegard of Bingen, a nun who lived from 1098 to 1180 A.D. Hildegard experienced visual auras caused by scintillating scotomas which inspired her to write the book Scivias documenting her visual experiences (Sacks, 2007). From these illustrations and written descriptions, Sacks (2007) was able to theorize that Hildegard was actually experiencing an array of scotomas and phosphenes. Sacks (2007)

The visual fields are the areas that are seen by each eye. A scotoma is a dim or totally black area in your field of vision or a small area of visual loss within the visual fields. There are often areas around the dim or black spot that have normal vision. A scotoma can therefore be thought of as an “island” of lost vision. Central scotoma means there is a blind area in the middle of the visual field, surrounded by normal vision. Scotomas do not always occur in the center of vision. They may be off

Background There was a point where my little brother had reoccurring migraines almost every day. When he went to the doctor’s office, the doctor stated that he needed to get more rest, reduce the lighting, and minimize stress factors. With this in mind, I wanted to extend my knowledge of this type of headache disorder. Migraine is the most common headache disorder and has a cumulative lifetime migraine incidence of 43% in women and 18% in men (Ekman, 2013). A migraine headache is usually a throbbing

Migraine Awareness Have you or a loved one ever been victim of migraines? In the United States, more than thirty-seven million people are victims of this condition, more than twelve percent of the population (Migraine Statistics 1). A migraine is “a recurrent throbbing that typically affects one side of the head and is usually accompanied by nausea and disturbed vision” (Google 1). Migraines mostly occur in females, with eighteen percent, followed by six percent of males that fall prey to the disease

Reflection Journal #1 Everyone has been through sometime of scotoma in their life. Everyone has it no one is ever going to be perfect with this situation. To start this off scotomas is when our past conditioning doesn’t match what we are looking at, we build blind spots to it. The problem with this is you do not know where it’s at. For an example of one is what Lou had said. How come some people did not find all of the F’s in the F card exercise. The reason behind it is most people read it phonetically

the cortical visual maps of abnormal retinal receptor distributions that are found in rod monochromacy (only possesses operating rod photoreceptors). Subject KN, aged 56 year old has a complete absence of cone photoreceptors. KN also has a central scotoma which has been estimated to be between 10 min and 1º, but estimates are error prone due to nystagmus. The results show that the cortex undergoes a remapping whereby the regions that would normally

Currently, she is compliant with these medications. She does state that she still has some neck pain and a visual field cut. On the day she arrived home from the hospital, she had a severe headache with a scintillating scotoma. This is the first time she ever had a scintillating scotoma. She has had migraines her whole life. She was seen by Coastal Neurology for a while and was doing great on Topamax 75 mg. She got off this to

other times. She gets two kinds of headaches. Her mild headaches are up to twice a week. She had been taking Excedrin, Aleve, Tylenol, or Advil for these. She has a more severe headache that may be preceded or associated with a scintillating scotoma. She is unclear about the quality of the blurred vision, although she notes that when she closes her eyes during one of these episodes, she does still see spots suggesting, a positive visual phenomenon, but she states in this visual blurring last

Macular Degeneration is related to retinal aging. It can be caused by long term exposure to UV light, cigarette smoking, and even by having light colored eyes. It can also be caused by not having enough dark green leafy vegetables in the diet due to lack of vitamin C, E, beta-carotene, and zinc. C. Incidence: Macular Degeneration is the most common irreversible central vision loss problem in people over 60 in the United States. D. Genetics or Genomics Considerations Macular Degeneration can be

Head-to-toe assessments are completed when a person is getting a complete physical or the doctor wants to be thorough with any findings that could relate to a potential concern. Starting with the top of the head, the provider works his way down analyzing each body part and asking questions along the way. A provider must first start out observing the patient generally taking in whatever they can see with the naked eye before going from body part to body part. Then the assessment starts at the very
