Vitreous hemorrhage density grading scale

Grade Vitreous hemorrhage density grading scale
Grade 0 No blood present in the vitreous, the entire retina is visible
Grade 1 Some hemorrhage present, which obscures between a total of 4 to 6 clock hours of retina. Laser photocoagulation (PRP) can be successfully performed
Grade 2 Hemorrhage obscures between a total of 3 to 10 clock hours of central and/or peripheral retina, or a large hemorrhage is located posterior to the equator, with varying clock hours of anterior retina visible. Laser is feasible, but a full panretinal photocoagulation (PRP) can not be placed
Grade 3 A red reflex is present, with no retinal detail seen posterior to the equator, precluding any photocoagulation
Grade 4 Dense VH with no red reflex present
