A Case of Eyeball Movement Disorder due to a Chondrosarcoma in the Cavernous Sinus

PURPOSE: To report a patient with an eyeball movement disorder due to a chondrosarcoma in the left cavernous sinus. CASE SUMMARY: A 33-year-old woman visited our clinic complaining of diplopia she hand for one month. She had been undergone two operation for the removal of chondrosarcoma in the left cavernous sinus, and she had left esotropia of 25 prism diopters in the primary position and limited abduction of approximately -1.5 in the left eye. Therefore she was treated with radiotherapy for six weeks. Three weeks after radiotherapy she had esotropia of 2 prism diopters in the primary position and limited abduction of approximately -1 in the left eye. Six weeks later, only limited abduction of approximately -0.5 in the left eye was present. CONCLUSIONS: Eyeball movement disorders, like abducent nerve palsy, may develop as a result of tumors of the cavernous sinus and may be improved by the appropriate treatment of such tumors.

Postoperative improvement of diplopia and eyeball movement disorder in patients with reconstructive surgeries for orbital fracture / 上海第二医科大学学报

Objective To observe the postoperative changes of diplopia and eyeball movement disorder in patients with orbital fracture. Methods The clinical data of 62 patients with reconstructive surgeries for orbital fracture were retrorespectively analyzed.The position,range of fracture and incarceration of extraocular muscles were determined by CT scanning.The eyeball movement and diplopia were examined and recorded pre-operation,3,6 and 12 months after operation,respectively. Results Among the 62 cases,23 were simple orbital wall fracture and the other 39 were complex orbital fracture.Eighteen of the patients with simple orbital wall fracture had diplopia and 19 had eyeball movement disorder of Ⅰ degree or Ⅱ degree before operation.Twelve months after operation,5 had diplopia ofⅠ degree or Ⅱ degree,and 5 had eyeball movement disorder of Ⅰ degree.For those with complex orbital fracture,36 had diplopia and 38 had eyeball movement disorder.Twelve months after operation,29 had diplopia(III degree diplopia in 6) and 22 had eye movement disorder.Among the 12 patients with complex orbital fracture who received operation within 3 weeks after trauma, only one had III degree diplopia,while 5 of the 23 with complex orbital fractures repaired 3 months after trauma had III degree diplopia. Conclusion Surgical management can effectively improve diplopia and eyeball movement disorder resulted from orbital fracture.Earlier treatment is superior to later treatment in regard with the effect of surgical intervention.
