A woman in her 50s who wore contact lens daily (Acuvue Oasys; 15 h/d) woke up with mild discomfort and a blisterlike formation on her right eye. She had no history of surgery or trauma. Her corrected visual acuity was 20/25 OU; her intraocular pressure was 14 mm Hg OD and 21 mm Hg OS. Biomicroscopy revealed a subepithelial, 2.5-mm, irregular patch of fresh blood at the 6:30-o’clock position in the cornea periphery. No superficial or deep corneal vascularizations were noted. There was no giant papillary conjunctivitis or limbal stem-cell deficiency visible with fluorescein staining only. The appearance of limbal hyperemia is a photographic artifact. Clinically, this was not present; cell phone focus is best only centrally (Figure).
