Each of these key questions was developed by the FMCSA in such a way that the answers will be useful in updating its current medical examination guidelines. The five key questions addressed in this evidence report are as follows: Key Question 1: Is monocular vision associated with an increased crash risk? Key Question 2: Do red-green color deficiencies (either protan or deutan) increase crash risk? Key Question 3: Is visual field (VF) loss associated with an increase in crash risk? And, if affirmative, what is the acceptable VF range in the horizontal and vertical meridians? Key Question 4: Do cataracts increase crash risk? And, if affirmative, does cataract surgery reduce this risk? Key Question 5: Is diplopia associated with increased crash risk?84
