If the subject reads 3 or fewer letters on line 1 at 4 Meters,
- A.
The VAE should test the subject for count fingers
- B.
The VAE should stop the test at 4M and move the subject to 1M
- C.
The VAE should attempt to test the patient on line 2 at 4M
- D.
The VAE should stop testing and write N/A for 1M testing
Correct Answer
B. The VAE should stop the test at 4M and move the subject to 1MExplanation
The correct answer suggests that if the subject reads 3 or fewer letters on line 1 at 4 meters, the VAE should stop the test at 4M and move the subject to 1M. This implies that the subject's visual acuity is too low to continue testing at 4 meters, so they need to be moved closer to the chart in order to accurately assess their vision.Rate this question:

Low Vision section should be crossed out (draw diagonal line through), initial and date under which of the following conditions:
- A.
The subject has received a Visual Acuity Score greater than ‘0’
- B.
The subject has been able to read letters at the 4M and/or the 1M distance
- C.
If the subject has a Snellen Equivalent score of 20/200
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above" because crossing out the Low Vision section and initialing and dating it is required under all three conditions mentioned in the options. If the subject has received a Visual Acuity Score greater than '0', it means their vision is not considered low and the section should be crossed out. Similarly, if the subject has been able to read letters at the 4M and/or 1M distance, their vision is not low and the section should be crossed out. Lastly, if the subject has a Snellen Equivalent score of 20/200, it indicates low vision and the section should be crossed out. Therefore, all three conditions require crossing out the Low Vision section.Rate this question:

Which of the following statements is incorrect:
- A.
If the subject reads 3 or fewer letters on Line 1 at 4M, move the subject to 1M for both refraction and testing
- B.
The Genentech VA stopping rule is once 3 or fewer letters are read correctly on any row, STOP testing on that row.
- C.
The Snellen Equivalent is the most difficult line read with a score of 4 or 5
- D.
The Genentech VA stopping rule is to continue testing the subject until he/she gets a score of ‘0’
Correct Answer
D. The Genentech VA stopping rule is to continue testing the subject until he/she gets a score of ‘0’Explanation
The given answer is correct because it states that the Genentech VA stopping rule is to continue testing the subject until he/she gets a score of '0'. However, this statement is incorrect because the Genentech VA stopping rule is actually to stop testing on a row once 3 or fewer letters are read correctly on that row.Rate this question:

The best method of occluding the eye that is not being tested employs the use of the following:
- A.
Occluding lens
- B.
Tissue
- C.
Tissue and tape
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The best method of occluding the eye that is not being tested is to use all of the above options, which include an occluding lens, tissue, and tissue with tape. Using an occluding lens ensures that no light enters the eye, while using tissue or tissue with tape provides a physical barrier to block the vision. Using all of these options together ensures maximum occlusion and prevents any interference during the eye test.Rate this question:

Left Blank
- C.
Zeros entered on each line
- D.
None of the above
Correct Answer
A. Lined through and initialed/dated.Explanation
The correct answer is "Lined through and initialed/dated." This means that any sections of the worksheet that are not completed, specifically the Low Vision sections, should be marked by drawing a line through them and then initialing and dating the mark. This indicates that the sections were intentionally left blank and not overlooked or forgotten.Rate this question:
