Vitreous haemorrhage means bleeding in vitreous cavity. Now a days principal cause of vitreous haemorrhage is diabetic retinopathy followed by trauma, or vasculitis. Small amount of vitreous haemorrhage usually absorbs within 3 months. But significant amount of haemorrhage or non-clearing vitreous haemorrhage needs surgical evacuation of blood by Vitrectomy operation. After Vitrectomy operation there may be chances of recurrent bleeding which may require repeat evacuation.
