Abstract
Objective To evaluate clinical features of extraocular muscles paralysis that initially presented with di -plopia.Methods Eighty cases with extraocular muscles paralysis were analyzed for causes of disease by reviewing medical history, a thorough physical examination and a complete eye examination .The clinical features were studied .Results Twenty-four patients with extraocular muscles paralysis were caused by diabetes , including oculomotor nerve paralysis ( 16 cases), abducent nerve paralysis (6 cases), and combination of oculomotor nerve and abducent nerve paralysis (2 cases). Twenty cases were caused by cerebrovascular diseases , and 18 cases were caused by arteriosclerosis resulted oculomotor and abducent nerve paralysis .Ten cases were caused by intracranial aneurysms ,two cases by myasthenia gravis ,one case by so-matization disorder ,two by intracranial tumors ,one by multiple sclerosis ,one by neurosyphilis ,and 1 by brainstem encepha-litis.Conclusions Many neurological diseases can cause nerve ophthalmic signs such as diplopia .The most common cau-ses including diabetic ophthalmoplegia , cerebrovascular disease , and aneurysms ophthalmoplegia .Atherosclerosis is also an important cause.Other etiologies include myasthenia gravis (ocular), somatoform disorders, intracranial mass, etc.The e-tiology of patients with extraocular muscles paralysis and diplopia is complex and easy to be misjudged .Therefore,much at-tention should be paid to the exact diagnosis and proper management .关键词
