Haab's striae is indicative of damage to which part of the eye?

1. Retina

2. Cornea

3. Descemet's membrane

4. Sclera

The correct answer is: Descemet's membrane

Haab's striae are lines or streaks that appear on the cornea of the eye and are most commonly associated with damage to Descemet's membrane. This condition typically arises in cases of congenital glaucoma where increased intraocular pressure leads to stress on the corneal layers. The appearance of Haab's striae indicates that the cornea has been put under strain, causing a tearing or stretching of Descemet's membrane. This damage can lead to a variety of visual complications and is often indicative of underlying conditions affecting intraocular pressure. Recognizing Haab's striae during an examination is critical for diagnosing and managing patients with potential glaucoma or other similar conditions that could compromise the health of the eye. Understanding the structure and function of the corneal layers, especially Descemet’s membrane's role in maintaining corneal transparency and integrity, is essential for recognizing the implications of such findings in clinical practice.
