1. PRINT A COPY OF THE EXAM, or back it up securely.

2. Open a file for your answers, and PUT YOUR NAME at the top of the file.

3. The exam is “open book,” so you may use books, notes or a calculator during the exam. But your answers must represent your own work, and you MUST NOT consult with anyone else during the exam.

4. Carefully read the directions for Parts I, II and III, and note the choice available to you. If you answer more than the required number of questions, answers beyond those required will not be graded.

5. The exam is graded out of 50 points.

6. The exam must be submitted to Canvas no later than 3:30 PM unless you have made other arrangements with the instructors. SAVE YOUR FILE BEFORE SUBMITTING IT TO Canvas.

Late submissions will be penalized one point for each minute late. For example, if you score 40 out of 50, but your exam was submitted 15 minutes late, your grade will be 25 out of 50 instead of 40 out of 50.

PART I: Essay Questions

Do TWO of the following THREE essay questions.

1. (12 points)

Jane was a bus driver. She contracted a serious infection that permanently damaged her corneas. No corneal transplant or other remedial treatment was possible.

Jane’s acuity dropped to 20/80, and her contrast sensitivity was quite low. She was no longer able to read the newspaper or traffic signs. She lost her job with the bus company.

a) Discuss Jane’s situation with respect to her disorder, impairment, disability and handicap.

b) Predict what you think her MNREAD performance would be like, and say why.

2. (12 points)

John was born with a droopy eyelid that occluded one of his eyes. He lived in a remote area and didn’t receive early treatment for this problem. He first saw an eye doctor when he was seven years old.

a) What do you think the doctor would discover about the acuities and fields of John’s two eyes? What impact would John’s problem have on learning to read?

b) The doctor was able to successfully treat the droopy eye lid. But what visual disorder was likely to remain even when the lid problem was corrected? What would be the perceptual consequences of this disorder?

c) Is john’s case similar to the case of Virgil, described by oliver Sacks? Comment briefly.

3. (12 points)

Peter came to his eye doctor with a number of visual complaints. Most distressing of all, when he looked directly at his wife, he couldn’t see her face. He had to look off to the side before he could get a blurry view. The doctor knew that Peter was about 70 years of age. Looking into his eye, the doctor detected some evidence of cataract, but he suspected some retinal disease as well.

a) What form of retinal disease do you think Peter had and why?

b) What would you expect the results of acuity, contrast sensitivity and field testing to be for Peter?

c) What would you expect Peter’s reading performance to be like? Would it benefit from magnification? What about contrast reversal? Why?

PART II: SHORT ANSWERS

Answer 10 of the following 15 questions. Be brief but specific. (20 points)

a) Roughly what percentage of people with low vision experience some form of photopsias or form hallucinations?

b) What are central scotomas?

c) What is an intraocular lens?

d) What is the purpose of LASIK?

e) What role do the photoreceptors play?

f) What pattern of field loss is typically associated with glaucoma?

g) What is meant by “critical print size” in the MNREAD test?

h) What is meant by the term “visual span” for reading?

i) What is “Mr. Chips?”

j) What is the “preferred retinal location (PRL)”?

k) What category of stimuli were used by Wurm et al. to study the advantages of color in object recognition? Why did they use this type of stimuli?

l) Our class TA described his study of object recognition in class. In his experiment, he measured the time (and accuracy) for recognizing objects as a function of what variable?

m) What is the basic idea behind direct cortical stimulation as a visual prosthetic?

n) What is the Pelli-Robson test?

o) Over what postnatal period does infant contrast sensitivity develop rapidly?
—————————————————————————————

PART III: LAB QUESTIONS.

Do 3 out of 4 questions. (6 POINTS)

a) What is the key difference between a CCTV magnifier and a computer screen magnifier?

b) If a person reads an MNREAD sentence in 4 seconds, what is the corresponding reading speed in words per minute?

C) Give an example of how the JFW screen reader adds additional auditory information to complement what is seen on the screen? Why are these auditory enhancements important to a blind/low-vision computer user?

D) What is the difference between grade I and grade II braille? How can one convert from grade I to grade II?
