Direct ophthalmoscopy for the acute physician - Papilloedema and other abnormalities of the optic nerve head

Direct ophthalmoscopy is an essential part of the full systemic examination. However, the technique is challenging and time-consuming. In the acute medical setting therefore, it is advisable for the physician to identify the subgroup of patients in whom examination of the fundus is most likely to be helpful. Ophthalmoscopy should be performed where papilloedema is suspected, in those with an altered level of consciousness or other focal neurology, those with an unknown systemic disorder, and those complaining of visual disturbance.
