Overcorrection after adjustable suture suspension- recession of the inferior rectus muscle in non-thyroid eye disease.
OBJECTIVE
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.
