↵Age indicates age related change without evidence of vitreoretinal disease.
CPVD = complete posterior vitreous detachment; PPVD = partial posterior vitreous detachment; TPVC = thickened posterior vitreous cortex; PDR = proliferative diabetic retinopathy; NPDR = non-proliferative diabetic retinopathy; BRVO = branch retinal vein occlusion; CRVO = central retinal vein occlusion.
