**Core Concept**
The clinical presentation of lid lag, enlarged cornea, and double contoured opacities suggests a condition affecting the cornea, specifically a developmental anomaly. The double contoured opacities are characteristic of a condition where the cornea fails to develop properly.

**Why the Correct Answer is Right**
This condition is caused by the failure of the cornea to develop properly, leading to an enlarged cornea. The double contoured opacities are due to the presence of a posterior embryotoxon, which is a prominent Schwalbe's line that appears as a double contour. The enlarged cornea and double contoured opacities are classic findings in this condition. The lid lag may be due to the shallow anterior chamber and the associated corneal enlargement.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not describe the characteristic double contoured opacities or the enlarged cornea.
* **Option B:** This option is incorrect because it is not associated with double contoured opacities or an enlarged cornea.
* **Option C:** This option is incorrect because it is a condition that affects the retina, not the cornea.

**Clinical Pearl / High-Yield Fact**
The double contoured opacities in this condition are due to the presence of a prominent Schwalbe's line, which is a classic finding. This is a key feature to look for in patients with this condition.

**Correct Answer: C. Peter's anomaly. This condition is a congenital anomaly of the anterior segment of the eye, characterized by a central corneal opacity, usually accompanied by a posterior embryotoxon.
