Haab's striae

Haab's striae are horizontal breaks in Descemet's membrane of the cornea that are associated with congenital glaucoma. They are named after the German ophthalmologist Otto Haab.

Overview

Haab's striae are horizontal breaks in Descemet's membrane of the cornea that are associated with congenital glaucoma. They are named after the German ophthalmologist Otto Haab. These striae are different from Vogt's striae, which are vertical and seen in keratoconus.

Symptoms

The main symptom of Haab's striae is the presence of horizontal lines or breaks in the cornea. These lines can be seen during an eye examination. Other symptoms may include increased eye pressure, enlarged eyes, and sensitivity to light.

Causes

Haab's striae are caused by increased pressure in the eye due to congenital glaucoma. This pressure causes the Descemet's membrane to break, resulting in the characteristic horizontal lines.

Diagnosis

Diagnosis of Haab's striae is made during an eye examination. The doctor will look for the presence of horizontal lines in the cornea. Other tests may be done to measure the pressure in the eye and to check for other signs of glaucoma.

Treatment

Treatment for Haab's striae involves treating the underlying cause, which is usually congenital glaucoma. This may involve medication to lower the pressure in the eye, or surgery to correct the problem.
