Corneal Blood Staining


Presentation

Rubeosis Iridis
  • Spontaneous hyphemas occur without inciting trauma and are usually caused by the abnormal growth of blood vessels, vascular anomalies, uveitis, tumors of the eye, rubeosis iridis, hemophilia, leukemia and other conditions or medications that cause thinning[flei.com]

  • iridis, myotonic dystrophy, leukemia, hemophilia, and von Willebrand disease. [1] Conditions or medications that cause thinning of the blood, such as aspirin, warfarin, or drinking alcohol may also cause hyphema.[en.wikipedia.org]
Visual Impairment
  • A 54-year-old man with a history of severe proliferative diabetic retinopathy in both eyes and profound visual impairment presented with severe corneal blood staining in the left eye secondary to a "spontaneous" total hyphaema and raised intraocular pressure[ncbi.nlm.nih.gov]
  • Hyphemas require urgent evaluation as they may result in permanent visual impairment. May result in hemosiderosis and heterochromia, elevation of the intraocular pressure for up to 6 days. Most resolve within 5–6 days.[standardofcare.com]
  • impairment. [ citation needed ] A long-standing hyphema may result in hemosiderosis and heterochromia.[en.wikipedia.org]
  • Those in or near the centre of the cornea increase risk of visual impairment.[patient.info]
Photosensitivity
  • Once the amount of hemoglobin overwhelms the keratocytes’ capacity to metabolize it, they undergo necrosis. 5 This observed cell death might be due to photosensitivity, as McDonnell et al found that hematoporphyrin derivatives accumulate in the cells,[millennialeye.com]

Prognosis

  • Prognosis: Cases of corneal blood staining secondary to hyphema have cleared spontaneously. One case cleared after 2 years without known intraocular pressure elevation. Many cases will have opacified corneas that require penetrating keratoplasty.[missionforvisionusa.org]
  • […] risk of rebleeding by inhibiting the conversion of plasminogen to plasmin, and thereby keeping clots stable. [2] However, the evidence for their effectiveness is limited and amioncaproic acid may actually cause hyphemas to take longer to clear. [4] Prognosis[en.wikipedia.org]

  • PKP prognosis is poor due to chronic ocular surface disease. Do alkali or acids cause worse chemical burns? What are signs of an unfavorable visual prognosis with alkali burns? Extensive limbal epithelial damage and intraocular chemical penetration.[quizlet.com]

Etiology

  • DISCUSSION Etiology of endothelial damage, seen consistently in CBS, remains unclear. Messmer et al found extracellular hemoglobin concentrated in the posterior stroma, whereas intracellular hemosiderin predominated anteriorly.[millennialeye.com]
  • Etiology: A combination of hyphema and resultant elevated intraocular pressure are believed to be important in the pathogenesis of blood stained corneas.[missionforvisionusa.org]
  • While formulating treatment plans, physicians should remember that the elevated IOP may be due to multiple concomitant etiologies and adjust their strategy accordingly.[glaucomatoday.com]

Epidemiology

  • On average, the increased pressure in the eye remains for six days before dropping. [3] Most uncomplicated hyphemas resolve within 5–6 days. [3] Epidemiology [ edit ] As of 2012, the rate of hyphemas in the United States are about 20 cases per 100,000[en.wikipedia.org]
