  • 1Department of Ophthalmology, College of Medicine, Kyung Hee University, Korea.


A series of 250 patients with paralysis of the third, fotrth and sixth cranial nerves, who were diagnosed at Kyung Hee University Hospital, was analyzed. All patients with a neuroophthalmologic problem who visited the Dept. of Ophthalmology or had a consultation from another were included. There were 116 cases(46.4%) of sixth nerve paralysis, 88 cases(35.2%) of third nerve paralysis, 24 cases(9.6%) of fourth nerve paralysis, and 22 cases(8.8%) of multiple cranial nerve involvement. The etiologic incidence of the third, fourth and sixth cranial nerve paralysis revealed that trauma was the most frequent(86 cases); other causes were undetermined(59 cases), vascular(37 cases) and tumor(17 cases), in that order. The most common type of recovery was with the fourth nerve paralysis(41.7%).
