Abstract
Purpose The purpose of this paper is to investigate how much correction is obtained per millimeter of medial rectus (MR) resection for recurrent exotropia after bilateral lateral rectus (BLR) recession, and to determine the difference in the effects between unilateral and bilateral resection, and the influence of previous lateral rectus (LR) recession on the effects of MR resection.

Ten years post-operative follow-up of 25 consecutive patients with intermittent exotropia have been performed. 13/25 patients are at follow-up fine, that is small and symptomfree exoforia, good sensorial binocular functions of normal type, sufficient although subnormal fusional amplitude and never exotropia. 8/25 patients are fair, that is only occasionally momentary occurrence of exotropia and binocular complaints. 4/25 patients are orthoptically poor (suppression on all tests), but without com...

It has been suggested that operating the dominant eye is a more effective way of treatment for exodeviations than the conventional non-dominant eye surgery. We have tested this idea in groups of children and adults with intermittent and constant exotropia. In a first group of 30 patients where the non-dominant eye was operated on, we found that our initial technique resulted in an undercorrection averaging 11 prism diopters. Modification of the technique, by increasing the relative amount of sur...

Purpose: To determine the cause of consecutive esotropia on the basis of the relationship between the location of the equator and a new insertional site of the recessed lateral rectus muscle in cases of intermittent exotropia. Methods: Ninety-two patients with intermittent exotropia, all of whom underwent recessions of both lateral rectus muscles (5 to 8 mm), were included.The distances from the limbus to the equator (LE distance) and from the equator to the new insertion of the recessed lateral...

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 ...

Purpose: Unilateral lateral rectus recession is an alternative procedure in the treatment of moderate angle intermittent exotropia. However, long-term results of unilateral lateral rectus recession have not yet been studied. The aim of this study was to determine the long-term stability of alignment following unilateral lateral rectus recession in patients with intermittent exotropia with a deviation of 25 to 30 PD. Patients and Methods: Thirty-two patients with intermittent exotropia with a dev...

Purpose: To study the efficacy of unilateral rectus resection in the surgical treatment of undercorrected or recurrent strabismus. Methods: A retrospective chart review of patients who had undergone a unilateral rectus resection with at least 6 months (mean 35.6 months) of postoperative follow-up was performed. Results: A resection of a single rectus muscle was undergone by 92 patients: 70 underwent a unilateral resection of the medial rectus and 22 underwent a unilateral resection of the latera...

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...

The results of recession of the lateral recti as a first procedure for exodeviation are compared for several initial (two to ten day) postoperative alignments. Eighty percent of all initial postoperative alignments changed by the eighth week, 71% becoming more divergent. Eighty-one percent of initial postoperative alignments between 11 and 20螖 of esodeviation remained satisfactory, as did 60% of initial esodeviations of up to 10螖. Initial postoperative orthophoria and exodeviation up to 10螖 rema...

The objective of this study is to compare the long-term outcomes of bilateral and unilateral medial rectus (BMR/UMR) resection for recurrent exotropia after bilateral lateral rectus (BLR) recession. Retrospective study was performed of 99 patients who underwent BMR resection (BMR group) or UMR resection (UMR group) for recurrent exotropia of 20鈥30 prism diopters (PD), with a minimum follow-up of 5 years. Surgical outcomes including success rate, exodrift rate, and average effect of MR resection ...

Purpose. To evaluate the surgical outcomes of unilateral or bilateral medial rectus (MR) muscle resection for recurrent exotropia after bilateral lateral rectus (BLR) muscle recession based on a novel surgical formula. Methods. Forty-one consecutive patients with unilateral or bilateral MR muscle resection for recurrent exotropia after BLR muscle recession were included in this retrospective study. All surgeries were performed according to the formula: 1.0鈥塵m MR muscle resection for every 5 pris...

Purpose: To investigate the dose-effect relationship of unilateral medial rectus resection for recurrent exotropia after bilateral lateral rectus recession. Methods: This study comprised 39 patients who underwent unilateral medial rectus resection for recurrent exotropia under 25 PD and bilateral rectus recession for prior surgery of exotropia. The medial rectus was resected from 5.0 to 7.0 mm according to angle deviation at a distance. The postoperative deviated angle was checked at one week, 3...

Although the surgical treatment is a relatively effective and predictable method for correcting residual or recurrent strabismus, such as posterior fixation sutures, medial rectus marginal myotomy, unilateral or bilateral rectus re-recession and resection, unilateral lateral rectus recession and adjustable suture, no standard protocol is established for the surgical style. Different surgical approaches have been recommended for correcting residual or recurrent strabismus. The choice of the surgi...

Purpose: The purpose of this study is to investigate the effect of unilateral medial rectus muscle resection (UMR) for the treatment of recurrent intermittent exotropia after bilateral lateral rectus muscle recession (BLR). Methods: Medical records of 121 subjects who underwent UMR for the treatment of recurrent intermittent exotropia after BLR with more than six months of follow-up were reviewed. Patients were classified into two groups, the 4-mm group who underwent 4-mm UMR and the 5-mm group ...
