Abstract
Purpose: :
To evaluate incidence of diplopia after full macular translocation and extraocular muscle surgery.
Methods: :
We present a retrospective analysis in a consecutive series of 88 patients underwent to full macular translocation and extraocular muscle surgery to counterrotate the eye from January 2003 an December 2007. Al patients had a sensorimotor examinations before surgery and 6-12-18-24 months after surgery.
Results: :
Preoperative median visual acuity was 1.08 logMAR in operated vs 1,68 in fellow eyes. Postoperative median visual acuity was 0.78 in operated. 15 (13,2%) patients had postoperative diplopia, 3 patients was successfully treated with application of prism lenses, 12 patients required a second extraocular muscle surgery to correct residual extorsion; this surgery was effective in treating diplopia in 11 cases. Overall 87 of 88 (98,8%) patients underwent to macular translocation was free of diplopia after 1 or 2 extraocular muscle surgeries and prismatic correction.
Conclusions: :
Extraocular muscle surgery is effective at relieving cyclotorsion induced by macular translocation. The majority of patients were free of disabling diplopia after extraocular muscle surgery.
