title: [A clinical analysis on 131 senile cases with diplopia].
abstract: OBJECTIVE
  To approach the pathogenic features of senile diplopia to elevate the rate of accurate clinical diagnosis and the therapeutic effect of treatment.
  
  
  METHODS
  Prism, synoptophore, Hess' screen and red glass test were used to examine the ocular position, muscle movement and diplopia image in 131 cases (aged 60 or older). Biochemical examination of blood and imaging diagnosis were also involved.
  
  
  RESULTS
  Among 131 cases, 120 (91.6%) suffered from binocular diplopia and 11 cases (8.4%) monocular diplopia. The majority of cases (110/120) with binocular diplopia were of ocular dyscinesia type resulting from intracranial vascular diseases, while the majority of cases with monocular diplopia resulted from complications of intraocular operation.
  
  
  CONCLUSIONS
  Most of the diplopia in the aged are binocular one whose main cause is ocular dyscinesia resulting from vascular diseases. The cause of monocular diplopia in most of the cases is frequently due to the complications of intraocular operation. The authors emphasize a thorough examination of patients with diplopia.
