Eye, Vitreous - Hemorrhage
comment:Vitreous hemorrhage ( Figure 1 , Figure 2 , Figure 3 , and Figure 4 ) is characterized by accumulations of extravasated blood in the vitreous. Retinal detachment and/or degeneration are often present concurrently. Vitreous hemorrhage can be due to leakage from persistent fetal (hyaloid) vessels or from retinal vessels, can follow trauma from intravitreal injections or retro-orbital bleeding procedures, or can be secondary to inflammation.
recommendation:Vitreous hemorrhage should be diagnosed and assigned a severity grade. If vitreal hemorrhage is secondary to other lesions (e.g., inflammation), it should not be diagnosed separately unless warranted by severity, but should be described in the pathology narrative.
