All of the following are true for anaemic retinopathy except
Anaemic retinopathy In anaemia, retinal changes are liable to occur when haemoglobin level falls by 50 percent and are consistently present when it is below 35 percent (5 gm%). Anaemic retinopathy is characterised by pale aerioles and a pale general background of the fundus. Retinal veins are dilated. Superficial retinal and preretinal (subhyaloid) haemorrhages may be seen in posterior half of the fundus. A few haemorrhages have white centres (Roth spots). Rarely, a few soft exudates (cotton-wool patches) may also be present. Ref:- A K KHURANA; pg num:-264
