**Question:** Persistent primary hyperplastic vitreous (PHPV) is associated with –

A. Persistent vitreous body
B. Coat's disease
C. Retinopathy of prematurity (ROP)
D. Congenital cataract

**Core Concept:**

Persistent primary hyperplastic vitreous (PHPV) is a rare developmental disorder that occurs when the primary vitreous body fails to involute (degrade) after birth, leading to a persistent, hyperplastic vitreous body. This condition can cause ocular complications in children and is often associated with other congenital ocular conditions.

**Why the Correct Answer is Right:**

The correct answer is D, Congenital cataract, because congenital cataracts are a group of conditions characterized by the formation of cataracts in the eye during childhood. In certain cases, persistent primary hyperplastic vitreous can lead to the development of congenital cataracts. The vitreous body is responsible for maintaining the clarity of the lens, and its persistence can interfere with the lens's transparency, resulting in cataract formation.

**Why Each Wrong Option is Incorrect:**

A (Persistent vitreous body) is incorrect because the persistent vitreous body itself is not a disease or condition, but rather a normal developmental structure that should involute after birth. It is the associated congenital cataract that is clinically relevant.

B (Coat's disease) is incorrect because Coat's disease is a group of disorders characterized by the inflammation of the retina, choroid, and sclera. It does not directly relate to persistent primary hyperplastic vitreous or congenital cataracts.

C (Retinopathy of prematurity) is incorrect because Retinopathy of Prematurity is a condition affecting premature infants, causing retinal damage and vascular abnormalities, not directly associated with persistent primary hyperplastic vitreous or congenital cataracts.

**Clinical Pearl:**

In clinical practice, recognizing the association between persistent primary hyperplastic vitreous and congenital cataracts is essential for accurate diagnosis and timely intervention. This understanding helps ophthalmologists to properly manage and treat these conditions, preventing potential vision impairment and preserving the child's ocular health.
