title: Vitreous haemorrhage in elderly patients: management and prevention.
abstract: Vitreous haemorrhage can be caused by a disruption of normal retinal vessels, bleeding from diseased retinal vessels, bleeding from abnormal new vessels or extension of haemorrhage through the retina from other sources. In the elderly, vitreous haemorrhage usually occurs spontaneously and only occurs occasionally as a result of trauma. Appropriate management of vitreous haemorrhage is dependent on the most likely cause in a particular patient. As always, an accurate medical history with a careful clinical examination, static and dynamic ultrasonography performed by an experienced examiner, results of other laboratory tests and an understanding of the common causes of vitreous haemorrhage in each age group is essential to come to a 'best guess' diagnosis as to the cause of the vitreous haemorrhage and thus guide the physician toward the appropriate management. Immediate surgical removal of blood if indicated, as well as improving the vision gives the added benefit of allowing a full examination of the underlying retina. For those in whom surgical removal of blood is not recommended, a careful and frequent follow-up with serial B-scan ultrasound allows the 'best guess' diagnosis to be confirmed at each visit, until such time as the vitreous haemorrhage resolves sufficiently to allow a full and proper examination of the retina. Where there is a confirmed retinal tear, retinal detachment or other fundal pathology these are treated appropriately with laser or surgery (vitrectomy). Preventative measures are dependent on the underlying cause of vitreous haemorrhage. Some of the underlying causes such as posterior vitreous detachment cannot be prevented. In others, such as retinal vein occlusion, measures may need to be taken so as to reduce the risk of a similar event in the same or fellow eye and to reduce the risk of potentially life-threatening associated systemic conditions such as a stroke or myocardial infarction.
