Abstract
Examination of the ocular fundus is a critical aspect of the neurologic examination.
For example, in patients with headache the ocular fundus examination is needed to
uncover “red flags” suggestive of secondary etiologies. However, ocular fundus examination
is infrequently and poorly performed in clinical practice. Nonmydriatic ocular fundus
photography provides an alternative to direct ophthalmoscopy that has been studied
as part of the Fundus Photography versus Ophthalmoscopy Trial Outcomes in the Emergency
Department (FOTO-ED) Study. Herein, the results of the FOTO-ED study are reviewed
with a particular focus on the study's implications for the acute care of patients
presenting with headache and focal neurologic deficits. In headache patients, not
only optic disc edema and optic disc pallor were observed as would be expected, but
also a large number of abnormalities associated with hypertension. Based upon subjects
with focal neurologic deficits, the FOTO-ED study suggests that the ocular fundus
examination may assist with the triage of patients presenting with suspected transient
ischemic attack. Continued advances in the ease and portability of nonmydriatic fundus
photography will hopefully help to restore ocular fundus examination as a routinely
performed component of all neurologic examinations.
