What term describes unequal pupil sizes?

Explanation:
Unequal pupil sizes are called anisocoria. This term captures the finding that one pupil is consistently larger or smaller than the other, which can be a normal variation in some people or indicate an underlying issue with the nerves that control pupil size. In practice, you’d compare the pupils in bright light and in darkness. If the difference is more noticeable in bright light, the problem is usually a reduced constriction (parasympathetic) on the larger pupil’s side. If the difference is more noticeable in dim light, it suggests a dilation (sympathetic) issue on the smaller pupil’s side. The other terms describe different eye findings—double vision, blood in the anterior chamber, or involuntary eye movements—not unequal pupil sizes.
