title: Clinical manifestations, character of aneurysms, and surgical results for unruptured cerebral aneurysms presenting with ophthalmic symptoms.
abstract: OBJECTIVE
  Cases with unruptured cerebral aneurysms presenting with visual symptoms were investigated about their site, size, symptom, operative methods and results.
  
  
  METHODS
  Between 1984 and 1999, 8 cases were treated in Sendai National Hospital. One man and 7 women, mean age 66.4 years. Ophthalmic symptoms were as follows: diplopia in 6, visual acuity deterioration in 2, impaired visual field in 2 and ptosis in 3. Aneurysm location was IC cavernous in 3, IC ophthalmic in 3, ICPC in 1 and Acom in 1. Aneurysms of more than 25 mm numbered 6 cases.
  
  
  RESULTS
  Operative methods and results were as follows: Direct clipping 3 cases, parent artery occlusion + EC/IC bypass 4 cases, Aneurysm trapping + EC/IC bypass 1 case. One patient who underwent direct clipping died following intraoperative complication. Of the remaining 7 cases, visual symptoms were improved in 4, remained unchanged in 2 cases, worsened in 1 case.
  
  
  CONCLUSIONS
  These results suggest that in cases with unruptured large or giant aneurysms presenting with ophthalmic symptoms, especially in IC cavernous or IC ophthalmic aneurysms, parent artery occlusion + EC/IC bypass is the safest operative procedure.
