Muscle transposition for the treatment of paralytic strabismus. Retrospective review of 23 cases

Abstract Introduction: Muscular transposition procedures are used when there is no ocular rotation in a particular direction due to alterations of the extraocular muscles such as paralysis, agenesis or congenital anomalies. The objective of this study is to characterize the patients treated with this procedure and determine the percentage of correction of the deviation angle obtained after surgery in the Pediatric Ophthalmology, Strabismus and Neuro-ophthalmology Unit. “Dra. Ana María Illescas Putzeys”, Hospital de ojos y oídos “Dr. Rodolfo Robles V. Methods: A retrospective, descriptive, observational study was conducted with review of records of patients operated on muscle transposition during the years 1999 to 2016. Results: Twenty-three rectus muscle transposition procedures were performed. Thirteen were male (56.5%). The mean age was 42 years. In our series, an average correction of 42 PD (82%) was obtained regardless of the type of paralysis or the surgical procedure performed. Conclusion: In selected cases of paralytic strabismus, the main approach may be only muscle transposition with augmentation (posterior intermuscular fixation suture), with good results, similar to those obtained with muscle transposition using adjuvants such as botulinum toxin treatment
