THE INCIDENCE of spontaneous vitreous hemorrhage is approximately 7 per 100 000. Dynamic vitreoretinal traction (DVRT) is the leading cause and accounts for more than one third of cases (DRVT with retinal tear—30%; DRVT without retinal tear—8%).¹ In this setting, the presence of blood in the vitreous cavity typically results from DRVT on a retinal vessel during vitreous separation. It is believed that the posterior hyaloid is more strongly adherent over the major retinal vessels, and traction with subsequent gel separation may lead to disruption of the vessel wall.

While the absence of vitreous hemorrhage or pigment cells in the vitreous is specific for excluding retinal tears, the presence of either mandates careful and often repeated examination of the ocular fundus. Retinal tears are present in about two thirds of patients with either vitreous hemorrhage or pigment cells.^2-3 Exclusion of retinal tears and/or retinal detachment . . . [Full Text of this Article]
