Accommodation and convergence insufficiency with left middle cerebral artery occlusion
American Journal of Ophthalmology
|July 15, 1988
Summary
A patient with a left middle cerebral artery embolism experienced convergence palsy and abnormal accommodation. This study highlights the brain
Area of Science:
- Neuroscience
- Ophthalmology
- Neurology
Background:
- Investigating the neurological underpinnings of ocular motor control.
- Understanding the impact of cerebral lesions on visual functions.
Observation:
- A patient with a left middle cerebral artery embolism presented with specific eye movement abnormalities.
- Computed tomography revealed left cortical damage, sparing the brainstem.
Findings:
- The patient exhibited convergence palsy and significant accommodation abnormalities.
- Reduced amplitude and markedly lowered velocity of accommodative responses were observed.
Implications:
- This case substantiates the critical role of the cerebral cortex in regulating accommodation and vergence.
- Findings contribute to understanding the neuroanatomy of binocular vision and focusing.
