Spontaneous absorption of lenticular material and bilateral; micropthalmos is seen in:
**Core Concept**
Spontaneous absorption of lenticular material and bilateral microphthalmos is a characteristic feature of a rare congenital condition. This condition is associated with abnormal lens development and subsequent absorption of lens material.
**Why the Correct Answer is Right**
The correct answer is a congenital condition known as **aniridia**. Aniridia is characterized by the absence or partial development of the iris, which is often accompanied by microphthalmos (small eye) and spontaneous absorption of lenticular material. This condition is usually associated with mutations in the PAX6 gene, which plays a crucial role in eye development. The absence of the iris and lens abnormalities are due to the failure of the lens placode to develop properly.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the condition described in the question.
**Option B:** This option is incorrect because it is not associated with spontaneous absorption of lenticular material and bilateral microphthalmos.
**Option C:** This option is incorrect because it is not a congenital condition that affects the development of the lens and iris.
**Clinical Pearl / High-Yield Fact**
Aniridia is often associated with other systemic abnormalities, including glaucoma, cataracts, and intellectual disability. It is essential to recognize the characteristic ocular features of aniridia to make an accurate diagnosis.
**Correct Answer: D. Aniridia**
