Abstract:
PURPOSE: To evaluate the efficacy of re-recession or extirpation of inferior oblique (IO) muscle in recurrent or undercorrected IO overaction (IOOA). METHODS: We reviewed the records of 26 patients (33 eyes) with the recurrent or undercorrected IOOA after the graded recession of IO muscle, who underwent re-recession or extirpation of IO muscle, and was followed up for at least 6 months. We performed extirpation of IO muscle overacting larger than +2 after 14 mm recession of IO muscle or larger than +3 after 10 mm recession of IO muscle. In case of +2 IOOA after 10 or 8 mm recession of IO muscle, we carried out 14 mm re-recession of IO muscle. IOOA under +1 was defined as a successful case after re-operation. RESULTS: Thirty one of 33 eyes (93.9%) were corrected successfully after re-operation; 24 eyes with extirpation of IO muscle (96.0%) and 7 eyes with 14 mm re-reccession of IO muscle (87.5%) were successful. CONCLUSIONS: One of the advantages of graded recession of IO muscle is that additional re recession or extirpation of IO muscle can be preformed if needed. Extirpation or 14 mm re-recession of IO muscle was effective re operation procedure to correct a recurred or undercorrected IOOA.
