title: The optometrist's role in the management of hypertensive crises.
abstract: BACKGROUND
  In hypertensive crises, ocular findings are pivotal to making correct management decisions. Joint National Committee on Prevention, Detection, and Treatment of High Blood Pressure (JNC-7) guidelines define hypertensive crises as blood pressure greater than 180/120 mmHg associated with signs or symptoms of target organ damage. Urgent cases are those without optic disc edema but that necessitate control within 24 to 72 hours. Emergent cases are those with optic disc edema, also known as malignant hypertension, demanding control within 1 to 6 hours.
  
  
  METHODS
  Two cases are illustrated, as might be seen in optometric offices, of severe stage II hypertension. In case 1, the acute elevation of blood pressure (220/110 mmHg), was assessed as an urgent case and was correctly managed with the primary care provider through outpatient care. The second case of acute elevation of blood pressure (250/150 mmHg) and ocular findings of severe hypertensive retinopathy was sent as an emergent case to the emergency room.
  
  
  CONCLUSIONS
  These cases exemplify optometric in-office decisions to effectively manage urgent and emergent cases of hypertensive crises. Utilizing an urgent versus emergent classification of retinopathy can lead to the appropriate management decision for these patients.
