What is the term for pupils that are of unequal size?

The term for pupils that are of unequal size is anisocoria. This condition can occur for various reasons, including physiological variations, trauma, neurological conditions, or pharmacological effects. In many cases, it is harmless and found in a significant portion of the population without any underlying pathology.

Contrast this with iris coloboma, which refers to a defect in the iris that can lead to an irregularly shaped pupil but does not specifically denote unequal pupil sizes. Myopia and hyperopia, on the other hand, are refractive errors related to the eye's inability to focus light correctly, affecting vision clarity, but they are not related to pupil size at all. Therefore, anisocoria specifically addresses the characteristic of having unequal pupil sizes, making it the correct terminology for this condition.
