What is the condition that describes if the amount of light information transmitted to the brain from one eye differs from that of the other eye?

The condition that describes a disparity in the amount of light information transmitted to the brain from one eye compared to the other is referred to as an afferent pupillary defect. This condition occurs when there is an impairment in the sensory pathway of the eye that affects pupil reaction to light. Specifically, when light is shined in the affected eye, the response of the pupil is less than it would be if it were normal, leading to a relative afferent pupillary defect.

In a healthy individual, shining a light into one eye should result in a constriction of both pupils due to the consensual reflex. However, if one eye has a defect in the afferent pathway, it will demonstrate a less robust or diminished response. This condition can be indicative of various underlying issues affecting vision, such as retinal detachment, optic nerve damage, or severe cataracts in the affected eye.

The other conditions mentioned, such as efferent pupillary defect (which relates to issues with the motor pathways), monocular blindness (where complete vision loss occurs in one eye), and binocular vision loss (involving impairment in both eyes), do not specifically address the differential transmission of light and sensory response between the two eyes in the same manner as an aff
