Abstract
BACKGROUND AND PURPOSE: To assess the comparative risk of overcorrection in non-thyroid eye disease for adjustable suspension vs traditional recession surgery. To determine the ideal initial postop' binocular alignment for adjustable suture surgery. METHODS: Retrospective analysis of records of 31 patients. Thyroid eye disease excluded. All had inferior rectus recessions by either adjustable suspension-recession suture technique (20 patients) or traditional fixed recession technique (11 patients). RESULTS: None of 11 patients in the traditional recession group were overcorrected, one was undercorrected. Five of 20 patients who had adjustable suspension sutures had overcorrections which ranged from 6 to 18 prism diopters (PD), mean 12 PD. Two adjusted patients required additional surgery for their overcorrections. Statistical analysis of difference: 1/11 or 9.1% vs 5/20 or 25%, p=0.38. (="clinically/medically significant" for this study). CONCLUSIONS: Overcorrection is more frequent with the postop' adjustable suspension suture technique. If postop' adjustment is made, undercorrection is recommended.
