Consensual light reflex in the right eye results in...

1. right pupil constriction

2. left pupil constriction

3. no pupillary response

4. eye twitching

The correct answer is: left pupil constriction

When there is a consensual light reflex in the right eye, it means that light is being shone into the right eye, but the response being observed is in the left eye. This phenomenon is a normal neurological response where both pupils constrict simultaneously when light is shone into one eye. Therefore, the correct answer is B - left pupil constriction. Option A is incorrect because it describes the direct response in the same eye where the light is shining, not the consensual response in the opposite eye as seen in this reflex. Option C is incorrect as there should be a pupillary response, specifically in the eye that is not being directly stimulated by the light source. Option D is incorrect as eye twitching is not a typical response in this scenario; the consensual light reflex primarily involves pupillary constriction.
