title: Visual disturbance due to internal carotid aneurysm.
abstract: This report deals with four cases of internal carotid aneurysms including three cases of supraclinoid internal carotid aneurysms and one case of infraclinoid internal carotid aneurysms. Clinical ocular findings resembling parasellar tumors or retrobulbar optic neuritis are noted. Therefore, the importance of careful study concerning optic nerve diseases is emphasized, employing a CT scan and carotid angiography, if necessary.
