The term that describes pupils that react with near vision but not to light is "Argyll-Robertson pupils." This specific phenomenon is characterized by the pupils' consensual reaction to accommodation while being non-reactive to direct light. This occurs typically due to a lesion in the midbrain, particularly affecting the Edinger-Westphal nucleus, which is responsible for the pupillary light reflex.

In the case of Argyll-Robertson pupils, the condition is often associated with neurosyphilis and other central nervous system disorders. The unique presentation of these pupils is an important clinical finding and can serve as a diagnostic indicator in patients with specific neurological conditions.

Other options do not match this specific pupil reaction pattern. For example, amaurosis fugax refers to temporary vision loss, anisocoria describes a condition where the pupils are unequal in size, and optic neuritis generally involves inflammation of the optic nerve, leading to vision changes but not specifically the reaction patterns described.
