**Core Concept**
Leber congenital amaurosis is a rare, inherited eye disease that appears at birth or in the first few years of life, causing severe visual impairment or blindness. It is characterized by **retinal dystrophy** and **photoreceptor degeneration**. The disease is usually diagnosed in the first year of life.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general features of Leber congenital amaurosis, which include **nystagmus**, **photophobia**, and **hyperopia**. The disease is caused by mutations in several genes, including **RPE65** and **AIPL1**, which are essential for **phototransduction** and **retinal development**.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, it's challenging to provide a detailed explanation. However, common features of Leber congenital amaurosis include **visual impairment** and **retinal abnormalities**.
**Option B:** Similarly, without the specific option, it's difficult to explain why it's incorrect.
**Option C:** Again, without the specific option, it's hard to provide a detailed explanation.
**Option D:** The same challenge applies to this option.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that Leber congenital amaurosis is a **genetically heterogeneous** disorder, meaning it can be caused by mutations in multiple genes. This highlights the importance of **genetic testing** in diagnosis.
