Roth spots (white-centred retinal haemorrhages) were classically descr
ibed as septic emboli lodged in the retina of patients with subacute b
acterial endocarditis. Indeed many have considered Roth spots pathogno
monic for this condition. More recent histological evidence suggests,
however, that they are not foci of bacterial abscess. Instead, they ar
e nonspecific and may be found in many other diseases. A review of the
histology and the pathogenesis of these white-centred haemorrhages wi
ll be provided, along with the work-up of the differential diagnosis.
