Abstract

PURPOSE
Vogt's striae are defined as vertical stress lines that occur deep in the affected stroma of keratoconus. The purpose of this study was to report a case of horizontal Vogt's striae in keratoconus. METHODS: A 21-year-old male without history of trauma or contact lens wearing presented with decreased visual acuity in both eyes. He complained of chronic habitual eye rubbing due to ocular itching. The best corrected visual acuity of his right eye was 20/30 and was 20/40 in his left eye. A scissoring reflex was seen in both eyes upon retinoscopic examination. On slit lamp examination, multiple and fine parallel horizontal lines in the deep stroma and Descemet's membrane were noted in his left eye. Corneal topography showed bilateral inferotemporal steepening with corneal thinning. The horizontal lines, which disappear after pressing the eyeball, are thought to be stress lines resembling Vogt's striae. RESULTS: To our knowledge, there have been no reports demonstrating horizontal stress lines resembling Vogt's striae in keratoconus patients. Here, we report a case of horizontal Vogt's striae in a keratoconus patient.
