Anisocoria describes a condition involving what?

Anisocoria refers specifically to a condition where there is a difference in the size of the pupils between the two eyes. This can occur for various reasons, including physiological variations, neurological conditions, or the effects of medications. In a healthy population, a small percentage of individuals may naturally have some degree of anisocoria without any underlying pathology. However, significant or newly developed anisocoria can indicate medical issues that necessitate further evaluation.

The other choices pertain to different ocular conditions. For instance, blind spots in vision are typically related to retinal or optic nerve issues. Loss of peripheral vision often indicates glaucoma or other retinal problems. Color vision deficiency refers to issues with differentiating colors, often linked to the cones in the retina. Each of these conditions is distinct from anisocoria, which solely concerns the unequal size of the pupils.
