Abstract
Purpose: To investigate the effect of unilateral medial rectus resection in recurrent exotropia under 25 Prism Diopter after unilateral or bilateral lateral rectus recession. Methods: A retrospective chart analysis was conducted for 21 patients who underwent unilateral medial rectus resection for recurrent exotropia under 25PD and uni- or bilateral lateral rectus recession for prior surgery of exotropia. The medial rectus was resected from 5.0 to 7.0 mm by 0.5 mm according to angle deviation at a distance. The postoperative deviated angle was checked at one week, three months and six months postoperatively to investigate the amount of corrected deviation per resected muscle. Results: The average preoperative deviation was 20.573.37PD. We resected mean 6.10.62 mm of the medial rectus. At one week after the surgery, the postoperative deviated angle was 2.004.32PD, After six months it was 6.577.40PD, and there appeared to be an increase of deviation. Ten patients (48%) fused before surgery and 12 (57%) after surgery. The corrected deviation per resected muscle was 2.881.08PD. Conclusions: Unilateral medial rectus resection is an effective surgical method for the treatment of recurrent exotropia under 25 PD after lateral rectus recession.

Purpose: To investigate the effect of unilateral medial rectus muscle resection for recurrent exotropia after bilateral lateral rectus muscle recession for intermittent exotropia Methods: A retrospective analysis was made of thirtypatients who underwent unilateral medial rectus resection for recurrent exotropia. All had prior bilateral lateral rectus recession for intermittent exotropia. Data were collected for age, the preoperative deviation, the postoperative deviation at 2 weeks, 3 months, 6 ...

The purpose of strabismus surgery is to realign the deviated eyeball. However, regardless of the application of the best surgical technique, strabismus always has a possibility to require resurgery.1 After surgery, in cases with recurrent exotropia with time, if diplopia were developed, for the cases whose binocular vision could not be maintained or the deviation were severe to the level that strabismus were shown in appearance, resurgery is required.2 For exotropia surgery, bilateral lateral re...

Purpose: Study by result analysis the proper recession amount according to the deviation angle after unilateral lateral rectus recession in exodeviation. Methods: A retrospective analysis data from 139 patients who underwent unilateral lateral rectus recession with 15~24PD exodeviation and monitored for 12 months or longer was performed. The analyzed patients were divided into 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm groups according to the surgical amount of recession and 15~18PD, 19~20PD, 21~24PD gr...
Purpose : This study was designed to determine the recurrence rate, the recurrence time after surgical correction of intermittent exotropia and the relationships between the factors and the surgical outcome of ntermittent exotropia. Methods: The surgical results were retrospectively investigated in 210 patients who had undergone surgery for intermittent exotropia with at least 3 months (average 26.3 months, range 165 months) after surgical correction. Surgical success was defined as a final dist...
Purpose: To evaluate the amount and pattern of change in deviation angle with time course after surgical correction of intermittent exotropia and to evaluate the effect of pre-operative deviation and operation age on post-operative deviation change. Methods: 54 patients who followed more than 60 months (60120 months, mean 71.7 months) after surgical correction of intermittent exotropia were selected. We defined 'satisfactory results' that alignment of orthotropia, under 10 esotropia and under 10...

Background: When surgery is required for an undercorrection or for a recurrent strabismus that is in the same direction as the previous deviation, traditional options have included a rerecession of the previously operated muscle(s), a marginal myotomy of the previously operated muscle(s) with or without a resection of the direct antagonist, or a bilateral resection of the antagonist muscles. While many surgeons prefer to perform a bilateral resection for these reasons, a unilateral resection wou...

Purpose: Bilateral lateral rectus recession is useful in the treatment of intermittent exotropia. A unilateral recession may be used in the treatment of small-to-moderate angle intermittent exotropia as well. An early overcorrection following bilateral surgery has been shown to carry the best prognosis for future alignment. The relationship between the early and late postoperative alignment following unilateral surgery is unknown. The current study was designed to establish this relationship. Me...

: Exotropia may progress during the childhood years, and the ideal time for surgical intervention remains uncertain. We reviewed our results following bilateral lateral rectus recession in 57 consecutive patients. In order to identify possible predictive covariates, we performed survival analysis using survival time as the time from surgery to failure. The patients' age at the time of surgery ranged from 11 months to 50 years (mean, 68 months). Follow up after surgery ranged from 1 to 105 months...

Sixteen patients with moderate angle esotropia of 30 to 35 prism dioptres were treated with a unilateral medial rectus muscle recession of 6 or 6.5 mm. Thirteen of sixteen patients (80%) were straight postoperatively or had 12 prism dioptres or less of esotropia. Three of the 16 had greater than 12 prism dioptres of esotropia, and none were exotropic. This procedure should be considered as an alternative approach in the treatment of moderate angle esotropia.

Purpose: To investigate and compare the clinical courses and surgical success rates of secondary operations in recurrent exotropia according to the type of first operation for correction of exotropia. Methods: A retrospective chart review was performed for all patients with recurrent exotropia of the basic or pseudodivergence excess types. In group A (36 patients), bilateral lateral rectus (LR) recession was performed as the first operation and unior bilateral medial rectus (MR) resection was pe...
