Abstract
Purpose: :
To compare motor and sensory outcomes following bilateral lateral rectus recession (BLRc) or unilateral recess/resect (RRc) surgery in patients with basic-type intermittent exotropia, X(T).
Results: :
Mean follow-up was 23.1 months for all patients. 77% had > 6 months follow-up. There was a lower rate of any esodeviation at 2 months for patients undergoing BLRc compared to RRc surgery (43.5% vs 68.8%, p = 0.13). Surgical success, defined as < 10 prism diopters misalignment at distance and near, was equivalent for both techniques (p = 0.51). However, successful alignment at near was greater in the BLRc group (91.3% vs 56.3%, p < 0.01). Mean postoperative stereoacuity improved dramatically in both groups. Mean postoperative alignment at distance and near was within 8 PD of orthophoria in both groups. Reoperation rate was 8.7% in the BLRc group and 6.3% in the RRc group (p = 0.79).
Conclusions: :
These results are not conclusive due to the small number of patients, but they suggest that BLRc and RRc are equally effective treatments for patients with basic-type X(T).
