Abstract
Purpose
To investigate the neuro-ophthalmic diagnosis and clinical manifestations of intracranial aneurysm.
Methods
A retrospective survey of 33 patients who were diagnosed with intracranial aneurysm and underwent neuro-ophthalmic examination from April 2008 to December 2016. Frequency of the first diagnosis of intracranial aneurysm in ophthalmology, neuro-ophthalmic diagnosis, location of intracranial aneurysm, examination of intracranial aneurysm rupture, and neurologic prognosis of Terson's syndrome patients were analyzed by image examination, neurosurgery, and ophthalmology chart review.
Results
Of the 33 patients, most patients (n = 31, 94%) were diagnosed with intracranial aneurysm at the neurosurgical department and only 2 patients were diagnosed initially at the ophthalmology department. Causes and association were: Terson's syndrome (n = 10, 30%), third cranial nerve palsy (n = 10, 30%), internclear ophthalmoplegia (n = 4, 12%), visual field defect (n = 3, 9%), optic atrophy (n = 3, 9%), sixth cranial nerve palsy (n = 2, 6%), and nystagmus (n = 1, 3%). The location of intracranial aneurysms were: anterior communicating artery (n = 13, 39%), medial communicating artery (n = 12, 36%), and posterior communicating artery (n = 5, 15%). Ten of 33 patients had Terson's syndrome, and 6 patients (60%) with Terson's syndrome had apermanent neurological disorder such as agnosia, gait disorder and conduct disorder.
Conclusions
Third cranial nerve palsy was the most common neuro-ophthalmic disease in patients presenting with intracranial aneurysm. The neuro-ophthalmic prognoses for those diseases were relatively good, but, if Terson's syndrome was present, neurological disorders (agnosia, gait disorder, conduct disorder) were more likely to remain after treatment.
