If a patient with normal vision undergoes a procedure that selectively damages the horizontal cells in their retina, which consequence follows?

A)Increased sensitivity to dim light
B)Loss of color vision acuity
C)Reduced lateral inhibition ability
D)Complete inability to detect motion

💡 Explanation

Horizontal cells mediate lateral inhibition in the retina, enhancing contrast and spatial resolution. Damage to these cells reduces the ability to differentiate between closely spaced stimuli, because lateral inhibition is diminished. Therefore, reduced lateral inhibition results, rather than other sensory impairments.
