Abnormal smallness of one or both eyes is known as which condition?

• A. micropthalmia
• B. anophthalmia
• C. macrophthalmia
• D. coloboma

Answer: (A)

Microphthalmia is the name for abnormal smallness of one or both eyes. It describes a globe that is smaller than normal, which can occur in one eye or both and may be isolated or part of a syndrome. In ultrasound, you’d expect a reduced ocular diameter compared with gestational age norms. This differs from anophthalmia, where no eye tissue is present; from macrophthalmia (macrophthalmia), where the eye is abnormally large; and from coloboma, which is a structural defect of the eye rather than a size issue. That’s why the best answer is microphthalmia.
