Haab's striae (and posterior embryotoxon)

Haab's striae, or Descemet's tears, are horizontal breaks in the Descemet membrane[1] associated with congenital glaucoma.[2] It is named after Otto Haab. These occur because descemet's membrane is less elastic than the corneal stroma. Tears are usually peripheral, concentric with limbus and appear as line with double contour.
