Ophthalmologic Manifestations of Brainstem Stroke Syndromes
Strokes involving the arteries supplying the brainstem can result in a variety of different ophthalmologic manifestations—such as ocular motor palsies, Collier lid retraction, ptosis, diplopia, gaze palsies, nystagmus, skew deviation, issues with accommodation, and abnormal pupillary constriction/dilation.
Deviation of eyes and head in acute cerebral stroke
2006年6月26日 · A marked horizontal eye and head deviation observed ~1.5 days post-stroke is not a symptom associated with acute cerebral lesions per se, nor is a general symptom of right hemisphere lesions, but rather is specific for stroke patients with spatial neglect.
Conjugate Eye Deviation in Acute Stroke | Stroke - AHA/ASA …
2006年9月28日 · CED was classified in the study according to the NIHSS criteria for the item “best gaze” as normal (0), partial gaze palsy (1), and forced deviation or total gaze paresis not overcome by the oculocephalic maneuver (2).
CT assessment of conjugate eye deviation in acute stroke
Conjugate eye deviation seen on clinical examination helps to localize pathology in acute ischemic stroke. Eye deviation can also be assessed on a CT head scan. The authors found that CT eye deviation reliably lateralizes to the ischemic hemisphere (positive predictive value 93%) without reference to clinical examination.
Stroke Patients' Visual Attention: Why They Look To Lesions
2024年10月26日 · Conjugate eye deviation can be observed on CT scans, where the eyes may be deviated to the right or left, depending on the location of the lesion. In some cases, the eye deviation may be away from the side of the brain lesion, as seen in thalamic infarction and non-stroke diagnoses such as seizures.
Abnormalities of gaze in cerebrovascular disease. SUMMARY Disorders of ocular motility may occur after injury at several levels of the neuraxis. Unilateral supranuclear disorders of gaze tend to be transient; bilateral disorders more enduring.
How do the eyes move together? New understandings help explain …
A classic clinical finding in a middle cerebral artery stroke is conjugate deviation of the eyes to the side of the lesion. 2,3,4 In the case of a right-sided stroke in a patient with a left-dominant brain, signals from the right brain to the left eye are disrupted, whereas signals from the left brain to the right eye continue to work (Fig. 2 an...
Profile of Gaze Dysfunction following Cerebrovascular Accident
Gaze dysfunction is common following stroke occurring in 23% of stroke patients with suspected visual impairment and accounting for 41.5% of all ocular motility abnormalities. Stroke lesions were located in cortical, brainstem, and cerebellar areas.
Conjugate eye deviation due to pontine infarction: Report of 2 cases
Conjugate eye deviation (CED) typically results from a hemispheric stroke involving the frontal eye field [1, 2]. Although brainstem lesions can produce conjugate eye deviation, few studies have correlated the characteristics of conjugate eye deviation with the localization of brainstem lesions.
The eyes have it: conjugate eye deviation on CT scan aids in early ...
2003年5月5日 · Conjugate eye deviation, a sustained shift in horizontal gaze toward the affected hemisphere, is a well-recognized finding in acute stroke. Several supranuclear lesions, such as in the cortical frontal eye fields or in the brainstem paramedian pontine reticular formation, can cause conjugate eye deviation. 2.
