One pupil is dilated and unreactive, while the other is normal (in this case, the right eye is dilated, while the left eye is normal in size). This could mean damage to the oculomotor nerve (cranial nerve number 3, CN III) on the right side, or indicate the possibility of vascular involvement. Both pupils are dilated and unreactive to light.
[7] [72] Initially, post-stroke individuals have flaccid paralysis. [70] As recovery begins, and progresses, basic movement synergies will develop into more complex and difficult movement combinations. [7] [72] Concurrently, spasticity may develop and become quite severe before it begins to decline (if it does at all).
Superior alternating hemiplegia (also known as Weber syndrome) has a few distinct symptoms: contralateral hemiparesis of limb and facial muscle accompanied by weakness in one or more muscles that control eye movement on the same side. [2] Another symptom that appears is the loss of eye movement due to damage to the oculomotor nerve fibers.
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Cycloplegia is paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation. [1] Because of the paralysis of the ciliary muscle, the curvature of the lens can no longer be adjusted to focus on nearby objects.
Ophthalmoparesis refers to weakness (-paresis) or paralysis (-plegia) of one or more extraocular muscles which are responsible for eye movements. It is a physical finding in certain neurologic, ophthalmologic, and endocrine disease. Internal ophthalmoplegia means involvement limited to the pupillary sphincter and ciliary muscle.
It’s not a cure — the improvements ended after scientists removed the temporary implant — and the pilot study included only Rendulic and one other stroke survivor. In test, zaps to spine ...
A head and neck CT angiogram can be performed within 6 hours of onset of symptoms to see where the occlusion may be located which can help in determining the cause of the stroke. [29] In people who die from a stroke an autopsy can reveal additional diseases or conditions beyond the stroke itself, as well as uncover uncommon causes of a stroke. [30]
