Clinical and histopathological manifestations
Earliest clinical sign of diabetic retinopathy
:microaneurysm, small outpouching from retinal capillaries and dot intraretinal hemorrhages
:all(type 1), 80%(type 2)-20years
Preproliferative retinopathy
:have increase in the number and size of intraretinal hemorrhages(cotton-wool spots)- indicate regional failure of retinal microvascular circulation(ischemia)
Clinical and histopathological manifestations
Proliferative retinopathy
:formation of new blood vessels->ominous prognosis for vision
New vessels
can extend into vitreous cavity,
hemorrhage into vitreous, resulting in visual loss,
can cause tractional retinal detachments from the accompanying contractile fibrous tissue
Late in the course of ds, new vs may form within the stroma of iris and may extend into ant chamberblocks outflow of the aqueous humor, causing neovascular gloucoma(elevation of intraocular pr)
:50%(type 1), 10%(type 2) - 15years
