1. Why do doctors measure reflexes during a diagnostic exam?

23. Consider both the symptoms and results for each of the three patients to answer the following:

       Were there any abnormal test results?

       Using your text, the library and the internet to perform research explain what condition you think could explain the patient’s symptoms and results? Explain why you suspect this condition?

       What causes the condition you believe this patient may have?

Derrick

Derrick is color blind

Color blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women

Maria

Maria has an Astigmatism

Astigmatism is caused by an eye that is not completely round and occurs in nearly everybody to some degree. For vision problems due to astigmatism, glasses, contact lenses, and even vision correction procedures are all possible treatment options.

A person’s eye is naturally shaped like a sphere. Under normal circumstances, when light enters the eye, it refracts, or bends evenly, creating a clear view of the object. However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy.
