Chipped or loose lenses and warped and wrinkled charts should be reported to the Study Coordinator for replacement. This statement is true because if the lenses of a device used in a study are chipped or loose, it can affect the accuracy of the measurements taken. Similarly, if the charts used in the study are warped or wrinkled, it can lead to inaccurate readings. Therefore, it is important to report these issues to the Study Coordinator so that they can be replaced and ensure the validity of the study results.

Conducting the BCVA examination accurately and consistently according to the Genentech VA Specifications is important because it directly affects the primary and secondary efficacy outcome measures of the study. Errors in conducting the examination could compromise the reliability and validity of the study results. Additionally, ensuring that the examination is expertly and consistently administered benefits the patients by providing them with reliable and accurate assessments of their visual acuity.

The statement is not universally true. While it is common practice to begin testing with the left eye, it is not a strict rule that testing must always start with the left eye. The order in which the eyes are tested can vary depending on the specific testing protocol or the preference of the examiner. Therefore, the statement is false.

This statement suggests that if a subject reads four or more letters on any one line, they are required to attempt the letters on the next line, even if they are unsure and feel like they are guessing. This implies that there is a rule or requirement in place that obligates the subject to continue attempting the letters on the next line, regardless of their confidence level. Therefore, the correct answer is True.

The purpose of conducting trial-frame refraction is to achieve the best vision correction in preparation for VA testing. This involves determining the appropriate prescription for the patient by using different lenses and adjustments. By conducting trial-frame refraction, the examiner can fine-tune the prescription and ensure that the patient's vision is optimized before proceeding with visual acuity testing.

A +0.75 sphere lens is added to accommodate testing at 1 meter. This type of lens is used to correct for hyperopia or farsightedness. By adding this lens, it helps to focus the light properly on the retina for clear vision at the specific distance of 1 meter.

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.

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.

Burning in bulbs refers to the process of running them continuously for a certain period of time before conducting any tests or measurements. This is done to stabilize the bulbs and ensure accurate and consistent results. In the case of BCVA testing, which measures visual acuity, it is important to burn in both new bulbs and replacement bulbs for 96 hours to ensure that they are functioning properly and to eliminate any potential variations or inaccuracies in the test results. Therefore, the statement is true.

Mathematical calculations on the Visual Acuity worksheets do not need to be verified because they are already checked by the Study Coordinator using a calculator.

A BCVA examination cannot be conducted on a study subject in a room with an expired certification, even if the VA Examiner has a valid certification from the sponsor. Both the room and the examiner's certification need to be valid for the examination to be conducted.

The Low Vision section should only be completed if all of the following conditions are met: the subject has received a Visual Acuity Score of ‘0’, the subject has not been able to read any letters at 4M and at 1M, and the subject has a Snellen Equivalent of 20/NA.

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.

The individuals responsible for fulfilling the role of Visual Acuity Examiner for this study may not be involved in other study assessments. This means that they should only focus on assessing visual acuity and not be involved in any other assessments or tasks related to the study. By doing so, it ensures that the visual acuity assessments are conducted by individuals who are solely dedicated to this specific role, which can help maintain the accuracy and integrity of the study results.

The given statement is false. According to the statement, the letters answered incorrectly by the subject are lined-through on the BCVA worksheet. However, the correct answer is false, which means that the statement is not true. Therefore, it can be concluded that the letters answered incorrectly by the subject are not lined-through on the BCVA worksheet.

In order to continue testing on the next row of the VA chart, the subject must correctly answer a minimum of 4 letters on any line. This means that they need to accurately identify at least 4 letters in order for the testing to progress to the next row.

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.

The statement "Low Vision Testing should be conducted on all subjects who have a Snellen Equivalent of 20/500 or worse" is incorrect because low vision testing should be conducted on all subjects who have a Snellen Equivalent of 20/70 or worse, not 20/500 or worse.

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.

The statement is false because for best-corrected visual acuity testing, one must obtain a reading of 15 foot candles.
