Summary: Sudden impairment of vision occurred in five patients with renal failure. In four cases the visual disturbance was attributed to a lesion in the cerebral cortex. In these cases mental confusion and other neurological lesions were present which suggested widespread involvement of the cerebrum. The lesions recovered rapidly suggesting that compression or spasm of cerebral vessels was an important factor in their production. The ocular and neurological signs were largely resolved by correction of the fluid imbalance and control of hypertension but in two cases some visual field defect persisted. In the fifth case visual impairment was initially due to bilateral retinal detachment, later complicated by severe hypertensive retinopathy.
