Clinical Research of the Remanent Diplopia Correction Operation After Orbital Fracture Repair.

Abstract

To investigate the occasion, method and effectiveness of the diplopic correction after the orbital fracture repair in Chinese patients with orbital fracture. This was a retrospective observational study of 64 patients with remanent diplopia after the reconstructions of orbital fracture were studied between January 2014 and June 2017. The different cause, operational occasions, and surgical techniques analyzed. All patients were followed for 6 months after the surgeries. After treatment, 64 patients with III degree diplopia were all performed the operations on extraocular muscles. Different operation was selected to different patients according to the examinational results of the extraocular muscles and passive drawer test, including rectos retropulsion, suspension, excise, Jensen's connection, and fixation to periorbital membrane. During the surgery, 25 patients had no diplopia in mainly functional visual fields, while 15 patients still had III degree diplopia. After 6 months, 27 patients had no diplopia in mainly functional visual fields, while 13 patients still had II degree diplopia. Among these 13 patients with III degree diplopia, 7 patients had no the diplopia of primary position of eye, and 6 patients had the diplopia of primary position. These 6 patients were suggested to wear the triangular prisms for improvement of the diplopia. The operations should be selected according to the examining results about eye movements and diplopia before and during the surgeries. Reasonable operations could correct diplopia and improve the eye movements effectually.
