Hội chứng tổn thương bẩm sinh di truyền điều kiện Bệnh cơ - mạn tính tiến bộ bên ngoài ophthalmoplegia nhược cơ dài thời gian của các khuyết tật có thể yêu cầu điều trị lăng kính hoặc phẫu thuật lác. Phụ thuộc vào việc điều trị các bệnh lý cơ bản. Nếu tổn thương là nguyên nhân mạch máu | 42 Regeneration after trauma May be aberrant and posttraumatic innervation may cause erroneous innervation of adjacent muscles. Others causes Migraine Ophthalmoplegic migraine Pediatric oculomotor lesions Congenital traumatic and inflammatory causes are most common. Diagnosis Fasting glucose Imaging especially to exclude aneurysm Differential diagnosis Botulism pupils Brainstem disorders and Miller Fisher Syndrome Congenital lesions Hereditary conditions Myopathy - chronic progressive external ophthalmoplegia Myasthenia Gravis Therapy Long duration of defects may require prism therapy or strabismus surgery. Prognosis Depends on the treatment of the underlying pathology. If the lesion is of vascular etiology resolution occurs usually within 4-6 months.

Qualities The trochlear nucleus is located in the tegmentum of the midbrain at the Anatomy inferior colliculus near the midline and ventral to the aqueduct. Axons leave the nucleus and course dorsally around the aqueduct and decussate within the superior medullary velum thus each superior oblique muscle is innervated by the contralateral trochlear nucleus . The axons exit from the midbrain on its dorsal surface and travel around the cerebral peduncle emerging between the posterior cerebral and superior cerebellar arteries with the oculomotor .
