The ocular microtremor record and the prognosis of the unconscious patient
Lancet (London, England)
|March 5, 1977
Abstract:
Ocular microtremor was recorded in 41 healthy subjects and 70 unconscious patients. Abnormalities of frequency and pattern were found in all the unconscious patients, the degree of abnormality being related to outcome. The ocular microtremor record is a potential aid to prognosis in the unconscious patient.
Insights
Ocular microtremor abnormalities were detected in all unconscious patients, with patterns correlating to patient outcomes. This eye movement measure shows promise for aiding prognosis in unconscious individuals.
Area of Science:
- Neuroscience
- Ophthalmology
- Clinical Neurology
Background:
- Ocular microtremor (OMT) is a physiological phenomenon.
- Assessing neurological status in unconscious patients presents diagnostic challenges.
Purpose of the Study:
- To investigate the utility of ocular microtremor recordings in evaluating unconscious patients.
- To determine if OMT patterns correlate with patient outcomes.
Main Methods:
- Ocular microtremor was recorded in 41 healthy controls and 70 unconscious patients.
- Analysis focused on frequency and pattern abnormalities of OMT.
Main Results:
- All unconscious patients exhibited abnormalities in OMT frequency and pattern.
- The severity of OMT abnormalities was directly related to the patient's outcome.
Conclusions:
- Ocular microtremor analysis reveals significant alterations in unconscious states.
- OMT recording is a potential tool for prognostic assessment in unconscious patients.
