• After sustaining blunt ocular trauma and total hyphemas, two patients quickly developed corneal blood staining in the absence of elevated intraocular pressure. Corneal blood staining has previously been reported to occur in association with hyphema and raised intraocular pressures. Although several bibliographic references acknowledge that corneal blood staining may occur without raised pressure, a careful review of the literature failed to reveal any well-documented cases.
