Genetics, Brain Structure, and Behavior Presentation Evaluation
When someone mentions the song “Georgia” they instantly think of the famous musician Ray Charles. His talent was unparalleled to anyone else of his time. He if famously knows for being a blind musician that made hit records. This paper will discuss the cause of his blindness as well as the theory as to how Ray Charles lost his vision.
The Theory
Born Ray Charles Robinson September 23, 1930 in Albany, GA during the great depression. Ray Charles didn't start to loose his sight until he was seven years old. The theory was that he started to loose his sight after witnessing the accidental drowning death of his younger brother in their mother's portable laundry tub according the Legends of American Music History site. ((Legends of American Music History, 2004). However, also based on the site there was no official cause of his blindness. There was one theory that his blindness was caused by untreated Glaucoma not from the tragic sudden death of his younger brother.
The Truth
Glaucoma is a group of eye diseases that can damage the eye's optic nerve and result in vision loss and blindness according to the National Eye Institute. (National Eye Institute, N.D). This could explain how Ray Charles's deteriorating vision happened over a period of years instead of instantly. The optic nerve is a collection of millions of nerve fibers from the eyes retina to the brain. The front part of the eye where fluid builds is the anterior chamber. In this chamber the fluid is used to lubricate nearby tissue. The fluid leaves this chamber at an open angle to meet the cornea and iris. As the fluids reach this section of the eye it flows to a drainage system that leaves the eye. If the drainage does not happen rather quickly it can cause pressure on the optic nerve. The increased pressure...
