Which term is used to describe unequal pupil sizes?

• A. Oculomotor dysfunction
• B. Anisocoria
• C. Nystagmus
• D. Strabismus

Answer: (B)

The term that accurately describes unequal pupil sizes is "anisocoria." Anisocoria can occur for a variety of reasons, including physiological variations where the difference in size is slight and does not indicate a pathological condition, or it can be a sign of an underlying medical issue. This may involve conditions affecting the nervous system, eye injuries, or other factors that influence pupil responses. The other terms listed refer to different ophthalmological conditions. Oculomotor dysfunction relates to issues with the cranial nerve that controls eye movement, which may indirectly affect pupil size but does not specifically denote unequal pupils. Nystagmus refers to involuntary eye movements and does not concern pupil size. Strabismus describes a condition where the eyes do not properly align with each other, which is unrelated to the size of the pupils. Therefore, anisocoria is the precise term that directly encompasses the concept of unequal pupil sizes.
