Bilateral horizontal Vogt's striae in keratoconus

To report a keratoconus case with bilateral horizontal Vogt's striae. The clinical findings of the patient and the development of the direction of striae are discussed. Vogt's striae, defined as vertical stress lines, are rarely horizontal. One patient with unilateral horizontal stress lines on his left eye has been reported in the literature. Our patient has horizontal Vogt's striae in both eyes. Horizontal Vogt's striae may be seen in keratoconus as a rare slit-lamp biomicroscopic finding.
