Improvement in visual acuity following surgery for correction of head posture in XXXX .

@entity1 @entity135 @entity346
PURPOSE: To report the effect of the @entity135 ( @entity135 ) correcting procedures on the visual acuity improvement in @entity1 with @entity346 ( @entity346 ) and the visual acuity improvement outcomes in different @entity135 correcting surgeries in @entity346 . METHODS: This was a prospective, non-randomized, interventional study. Twenty-eight @entity1 underwent the Anderson-Kestenbaum procedure or the modified Anderson procedure with or without tenotomy of at least one horizontal recti for correction of @entity135 . Best-corrected binocular null zone acuity and degree of @entity135 was recorded preoperatively and compared with those done 1 month postoperatively. RESULTS: The average null zone logarithm of the minimum angle of resolution acuity was 0.42 preoperatively, which improved significantly to 0.33 postoperatively (P = .002). The @entity135 ranged from 10   to 40   (mean: 20.89  ), which improved significantly to a mean of 3.21   (P = .000). No significant difference (P = .65) was found in the visual acuity improvement among @entity1 who underwent the Anderson-Kestenbaum procedure or the modified Anderson procedure with or without tenotomy. No significant difference in the visual acuity improvement was seen in @entity1 who underwent tenotomy of at least one horizontal rectus muscle along with the modified Anderson procedure compared to those who underwent the modified Anderson procedure alone (P = .28). CONCLUSION: The procedures used mainly for correction of @entity135 in @entity346 do yield significant improvement in the visual acuity. This improvement is seen in @entity1 undergoing surgery for both horizontal and vertical @entity135 .
