Haab striae are horizontal or curved breaks in the cornea's inner layer known as Descemet's membrane. These lines form when the cornea stretches due to increased eye pressure, most often early in life. The breaks appear as pale or cloudy streaks when viewed during an eye exam. Haab striae are usually linked to congenital or early-onset glaucoma. While the lines themselves do not heal, eye pressure control helps prevent further damage.
read more about haab stria ...Haab striae develop when pressure inside the eye rises enough to stretch the cornea. This stretching can tear the inner corneal layer, creating visible lines. The condition often appears during infancy or childhood when eye tissues are more flexible. Pressure-related corneal changes are most commonly tied to pediatric glaucoma. Early diagnosis plays a role in limiting progression.
Haab striae are commonly associated with pressure-related eye conditions:
Haab striae can affect how light passes through the cornea if the lines cross the visual axis. Some people experience blurred or distorted vision as a result. The presence of these lines often signals long-term pressure exposure rather than a sudden change. Monitoring eye pressure helps protect remaining corneal clarity. Vision outcomes depend on how early treatment begins.
In infants and young children, the cornea is more flexible, so high eye pressure can stretch it more easily than it would in adults. That stretching can create breaks in Descemet's membrane, which show up as pale curved lines on exam. The presence of these lines often suggests the eye has been under pressure for a while rather than a single short spike. Pressure control matters mainly to prevent new damage and protect corneal clarity going forward.
No, Haab striae do not disappear once they form. The breaks remain visible even if eye pressure is controlled. Treatment focuses on preventing new striae rather than reversing existing ones.
Haab striae themselves usually do not cause pain. Any discomfort is more often linked to pressure changes or related eye conditions. Many cases are found during routine exams rather than from symptoms.
They are far more common in infants and young children. Adult corneas are less flexible and less likely to stretch in the same way. Similar corneal changes in adults usually have other causes.
Eye doctors identify Haab striae during a slit-lamp exam. The lines appear as horizontal streaks on the cornea. Pressure testing often accompanies the exam.
