What term describes the condition of having unequal size of pupils?

• A. Anisocoria
• B. Diplopia
• C. Nystagmus
• D. Periorbital

Answer: (A)

The term that describes the condition of having unequal size of pupils is "Anisocoria." This term comes from the Greek words "aniso," meaning unequal, and "koria," referring to the pupil of the eye. In clinical practice, anisocoria can occur as a normal variant in some individuals without any underlying pathology, but it can also indicate various medical conditions, such as neurological disorders, local eye problems, or systemic conditions affecting the autonomic nervous system. Recognizing anisocoria is important for healthcare professionals as it can serve as a significant indicator during a neurological examination.

The other terms do not relate to pupil size. "Diplopia" refers to double vision, "nystagmus" is characterized by involuntary eye movement, and "periorbital" describes the area around the eye. Thus, these terms are not applicable in the context of pupil size and function.
