ABSTRACT
PURPOSE:
To describe the results achieved using muscle belly union associated with the recession of the ipsilateral medial rectus muscle to treat myopic myopathy and restore the normal anatomical relationship of superior and lateral rectus (LR).METHODS:
A retrospective, nonrandomized study performed on 33 eyes of 26 patients who underwent muscle belly union between January 2004 and October 2012. We preoperatively and postoperatively recorded best-corrected visual acuity; refraction; intraocular pressure; complete orthoptic assessment, including the angle of deviation and maximal abduction measured using the Goldmann perimeter. Pictures of the eyes in all gaze directions were taken before and after the surgical treatment. Anatomical relationships between muscle cone and eye globe were preoperatively analyzed using magnetic resonance imaging (MRI). Surgical complications were noted.RESULTS:
The follow-up period was 6 months. Preoperative mean BVCA was 0.97 ± 0.96 logMAR (ranging from 0.1 to 3 logMAR) and no changes were detected during postoperative controls. Preoperative mean hypotropia and esotropia were, respectively, 10.2 ± 3.9 prism diopters (PD) and 46.2 ± 15.5 PD. Postoperative mean hypotropia was 2.48 ± 2.00 PD (P<0.001) and mean esotropia was 7.36 ± 9.09 PD (P<0.001). A statistical incrementation of mean maximal abduction (P<0.001) was also noticed.CONCLUSIONS:
Muscle belly union-coupled with the recession of the ipsilateral medial rectus muscle when considered convenient-is the elective surgical technique in myopic myopathy, when a downward displacement of LR muscle is shown on MRI with coronal sections.
