## **Core Concept**
Haab striae are a specific type of ocular finding associated with **buphthalmos**, which is the enlargement of the eyeball due to increased intraocular pressure. This condition typically occurs in infants and young children.

## **Why the Correct Answer is Right**
The correct answer, **D. Infantile glaucoma**, is associated with Haab striae because these are characteristic horizontal breaks in Descemet's membrane of the cornea. They occur due to the increased intraocular pressure in infantile glaucoma, leading to corneal stretching and thinning. This results in the appearance of horizontal or double horizontal breaks in the cornea.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because Haab striae are not typically associated with conditions like **retinoblastoma**. Retinoblastoma is a malignant tumor of the retina and does not directly cause the mechanical stress on the cornea that results in Haab striae.
- **Option B:** This option is incorrect as **cataract** does not directly cause Haab striae. While cataracts can occur in infants and children, they do not lead to the increased intraocular pressure that causes corneal stretching and Haab striae.
- **Option C:** This option is incorrect because **uveitis** does not typically cause Haab striae. Uveitis refers to inflammation of the uvea and can lead to various ocular complications but is not directly associated with the mechanical stress on the cornea characteristic of increased intraocular pressure.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Haab striae are pathognomonic for **infantile glaucoma**. Their presence significantly supports the diagnosis of this condition. Clinicians should be aware that the appearance of Haab striae necessitates a thorough ophthalmological examination to confirm the diagnosis and initiate appropriate treatment.

## **Correct Answer:** D. Infantile glaucoma
