Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system. [1] Electronystagmography is used to assess voluntary and involuntary eye movements. [2]
The physiologic basis of the head tilt test was explained by Alfred Bielschowsky and Hofmann [8] in 1935. [9] However, Nagel described it 30 years prior to Bielschowsky when he noted that the combined action of the superior rectus muscle and the superior oblique muscle of one eye and of the inferior rectus and inferior oblique muscles in the fellow eye causes incycloduction and excycloduction ...
As the eyes converge, the pupils should constrict. The optokinetic nystagmus test is optional and involves asking the patient to look at a strip of vertical lines moving horizontally across visual field. Nystagmus is normally observed. Extraocular movements are tested by inspecting for ptosis, eye position and nystagmus. The pupil size is ...
According to U.S. Census data, nearly 86% of Kansans and more than 89% of Missourians live within a 30-minute drive of an ophthalmologist, numbers that jump to almost 100% when looking at a drive ...
