Causes of diplopia.

ABSTRACT

A prospective study of 96 diplopia patients was analyzed concerning the common types and causes in order to develop early and proper management. Two-thirds (62) of the patients were male (64.6%). The average age was 34.5 +/- 15.7 years (+/- SD). The result revealed that the common types of diplopia were horizontal, vertical and torsional diplopia, respectively. The common causes of diplopia were head trauma (38.5%), systemic diseases from diabetes mellitus, hypertension (20.8%), undetermined group (15.6%), eye diseases (9.4%), and etc. Sixth cranial nerve paralysis was frequently found among the third, fourth and sixth cranial nerves. There were 13 cases of spontaneous fusion in the primary position. Only 7 of 12 surgical cases eventually achieved satisfactory alignment and fusion.
