How is pupil shape described when there is an inequality in size?

• A. Anisocoria
• B. Mydriasis
• C. Miosis
• D. Nystagmus

Answer: (A)

The term used to describe an inequality in pupil size is anisocoria. This condition can occur due to various reasons, including differences in neurological function, local eye conditions, or systemic issues affecting the autonomic nervous system. In typical scenarios, one pupil might appear larger or smaller than the other, leading to this asymmetry. Mydriasis and miosis refer specifically to the dilation and constriction of the pupils, respectively, without addressing the comparative size between the two pupils. Mydriasis indicates enlarged pupils, whereas miosis pertains to constricted pupils. Nystagmus, on the other hand, refers to a condition involving involuntary eye movements and does not relate directly to pupil size or shape. Therefore, anisocoria is the appropriate term to use when describing the phenomenon of unequal pupil sizes.
