The following is not true about microspherophakia
**Core Concept**
Microspherophakia is a rare congenital anomaly characterized by a small, spherical lens in the eye. This condition often leads to progressive myopia and other ocular complications due to the abnormal lens shape and position.
**Why the Correct Answer is Right**
The characteristic features of microspherophakia include a small lens size, spherical shape, and an increased risk of cataract formation, glaucoma, and retinal detachment. The spherical lens shape is a result of a failure in lens development during embryogenesis, leading to an abnormal lens morphology.
**Why Each Wrong Option is Incorrect**
**Option A:** Microspherophakia is often associated with other systemic anomalies, such as Marfan syndrome and homocystinuria. This statement is true, making Option A incorrect.
**Option B:** Microspherophakia is a rare condition, and its exact prevalence is unknown. However, this statement is not false, and Option B is not the correct answer.
**Option C:** The characteristic lens shape in microspherophakia is a result of a failure in lens development during embryogenesis. This statement is true, making Option C incorrect as it is the correct answer.
**Clinical Pearl / High-Yield Fact**
Microspherophakia is often associated with other systemic anomalies, such as Marfan syndrome and homocystinuria, which highlights the importance of a thorough systemic evaluation in patients with ocular anomalies.
**Correct Answer:** C. The characteristic lens shape in microspherophakia is a result of a failure in lens development during embryogenesis.
