The main cavity of the eye is filled with a usually clear gel called vitreous. Vitreous undergoes a natural aging process and becomes progressively liquid.
Normal eye movement may cause the vitreous to pull on localized areas of retina causing flashes (photopsias).
Normally the gel is only loosely adherent to the retina and shifts gently away during age-induced degeneration (also called syneresis). This event is called a posterior vitreous detachment (PVD) and is a normal event occurring in most people sometime between 50 and 70 years of age.
Occasionally, the vitreous gel adheres to the retina and creates a tear. If this break involves a retinal blood vessel bleeding into the vitreous, vitreous hemorrhage occurs. Patients often describe an abrupt onset of multiple dark spots and strands with no associated pain.
What is the treatment for Vitreous Hemorrhage from Retinal Tears?
Limited vitreous hemorrhage (VH) is usually managed conservatively with activity restrictions and positioning. Vitrectomy intervention may be necessary to clear persistent blood obscuring vision. Vitrectomy may also be indicated if the causative retinal break cannot be indentified and treated in the office sitting.
