- Background
and Objectives : Subjective visual vertical and horizontal presented as test that evaluate otolithic organ. However, was not discussed about condition that is factor influencing in examination or position at examination. Therefore, we wished to evaluate effect of subjective visual vertical and horizontal in each test condition and find repletion item.
Materials and Method : Measured subjective visual vertical and horizontal dividing by gender and three age group to 45 normal persons. Do so that there may be axis of rotation of 0.3×20 cm size candlepin on center of screen and lower part of screen to 18 inch LCD monitor at subjective visual vertical. Do so that may be center of screen and left middle at subjective visual horizontal and gave change length and axis of rotation of candlepin. Measured subjective visual vertical and horizontal each 3 times in standing, sitting, supine position in darkroom.
Results
: There are no statistical differences in each positions and distinction of gender and axis of rotation. But there are statistical differences in age groups.
Conclusion
: Difference in age groups means that examination method or control of number of test, preliminary
education of patients, assistance need rather than is caused change or abnormality of otolithic organ. Therefore, is
thought to be representative test that evaluate function of otolithic organ as clinical test.

Abstract
PDF
- A case is reported of downbeat nystagmus associated with compression of the root of vestibulocochlear nerve by
vertebral arteries, which was revealed by magnetic resonance imaging. Chief complain of the patient was positional
vertigo, which aggrevated at left decubitus position. Downbeat nystagmus was increased in left Dix-hall pike test.
Tetsuo et al, reported downbeat nystagmus with compression of dolichoectatic vertebral arteries to the medulla
oblongata and surgical neurovascular decompression of the dolichoectasia reverses the progression of symptoms if
permanent neurologic damage has not already occurred.
Key Words : Vertical nystagmus, Vertebrobasilar dolichoectasia, Vestibulocochlear nerve

- Background
and Objectives: The patient presenting to the emergency department with the complaint of dizziness is one of the most common as well as most challenging problems confronting the emergency physician today. Dizziness is a vague symptom of disease ranging from serious to benign. The differential diagnosis and proper management of dizziness in a department of emergency medicine are the most important things. We undertook this study to evaluate the character and clinical analysis of the dizzy patients and to discuss the significance and necessity of primary care in a department of emergency medicine.
Materials and Method: From September 1999 to October 2003, we sampled the 1,371 dizzy patients who visited the Emergency Department(ED). Of these patients, the 650 patients performed electronystagmography(ENG) and rotatory chair test were selected, except for the patients with loss of consciousness, known psychiatric disease or direct brain injury.
Results
The 650 patients were attributed to acute peripheral vestibulopathy in 88.5% (575 patients) of patients, benign paroxysmal positional vertigo in 9.5% (62 patients) of patients, central origin in 1.4% (9 patients) of patients, other organic origin in 0.6% (4 patients) of patients. In a retrospective analysis of patients with central origin, the symptoms estimated at central origin, for example, persistent headache, were found.
Conclusion
The exact diagnosis and management for the dizzy patients in a department of emergency medicine require the primary physician's concern and understanding for dizziness.
