The preretinal blood in this 70YO male with proliferative diabetic retinopathy (PDR) has multiple layers.
The red arrow highlights subhyaloid blood, while the yellow arrow shows the yellowing, devitalized subhyaloid blood just above. The blue arrow shows subhyaloid blood emanating from disc neovascularization. Last but not least, the twister of blood within the vitreous gives the appearance of a tornado literally shaking up all of this blood.
Panretinal photocoagulation was started.
