Abstract

We evaluated 38patients with orbital wall fracture, who were repaired surgically after its diagnosis from January 1986 to October 1995. We analysed its clinical symptoms and signs, ocular motlity disturbances and strabismus remaining after reduction. All the aptients showed diplopia due to ocular motility disturbance, it was greater in the patients with large fracture size and inferior wall fracture. The ocular motility disturbance remaining after the reduction was proportional to the fracture size and the time between trauma and its reduction. The exotropia and hypertropia of the fracturd eye were the main types of strabismus remaining after reduction. It was more severe in the patients with large fracture size and upper grade of ocular motility disturbance. The weakening procedure of horizontal and vertical muscle resulted in good correction for the strabismus.
