Abstract
Introduction: The surgery of choice for intermittent exotropia (XT) continues to be debated, with little evidence that one procedure provides a more successful outcome than the other in the longer term. Many factors, however, may potentially influence the outcome of strabismus surgery for intermittent XT. This study aimed to investigate factors associated with the recurrence of an exo-deviation following horizontal muscle surgery for intermittent XT of the divergence excess type. Methods: We retrospectively reviewed the medical histories of patients who underwent surgery for the correction of intermittent XT between January 1998 and June 2005. The factors analyzed were as follows: sex, age of onset, age at initial surgery, family history, size of preoperative deviation, near binocular single vision, amblyopia, oblique dysfunction, refractive error, type of surgery, and postoperative alignment. Results: Eighty-nine patients were included in the final analysis. Of these, 19 demonstrated recurrence of their ...

The surgical management of intermittent exotropia has been subject to wide discussion and debate in the literature. In general, recommendations for best practice guidelines for the surgical management of this condition are not possible due to the conflicting finding of various studies and a lack of high quality evidence. The main issues concerning surgical intervention relate to the timing, type and amount of surgery. This paper presents a review of the current literature with a particular focus...

Top of pageAbstract Purpose Few reports have included large numbers of exotropia patients. Thus, we undertook this study to perform a survival analysis of over 350 patients with exotropia and to determine which factors might affect the outcome of exotropia surgery. Methods The clinical records of 365 patients who underwent exotropia surgery by one surgeon were retrospectively reviewed. Preoperative patient characteristics, surgical procedures performed, and early postoperative ocular alignment w...

The cause of intermittent exotropia 「X(T)」 is unclear but X(T) is the most frequently acquired exotropia which develops in Korean children. Surgery is mainly used to treat X(T). X(T) can be cured through surgery but there is a 20-50% recurrence rate depending on the follow-up period.1 In Korea, Kim and Cho2 reported the incidence of postoperative undercorrection of X(T) to be 27%. In other countries, Richard and Parks3 reported an incidence of 38% and Clarke and Noel4 an incidence of 50%. Among ...

Background: The surgical management of intermittent exotropia, or X(T), remains a challenge. Not only are some quoted success rates relatively low (40-83%), but the outcome is notoriously unpredictable with a tendency to exotropic drift over time. Methods: In this retrospective study, 118 patients who underwent either bilateral lateral rectus muscle recession (BLR) or unilateral medial rectus muscle resection and lateral rectus muscle recession (R&R) surgery during a 4-year period were reviewed....

Purpose: To determine the clinical course of recurrent exotropia after a secondary operation for exotropia. Methods: The surgical results in 58 patients who had undergone reoperation for recurrent exotropia (reoperation group) were retrospectively investigated and compared with those of 100 patients who had undergone primary strabismus surgery only (primary operation group) using survival analysis. Results: In the reoperation group, recurrence occurred in 19 of the 58 patients (33%). Survival an...

Methods Case files of 225 patients with a diagnosis of primary exotropia were evaluated. Information about patient age at onset of deviation, patient age at surgery, interval between onset and surgery, preoperative deviation, refractive errors, degree of anisometropia, visual ac...

Abstract PURPOSE: To determine whether time of strabismus surgery for patients with acquired intermittent exotropia and constant exotropia influences postoperative sensory outcome. METHODS: In a retrospective, cross-sectional study, 76 patients with acquired intermittent or constant exotropia and motor realignment were evaluated for postoperative sensory status. Age at surgery, duration of exotropia, and presence of intermittent or constant exotropia were correlated with postoperative sensory st...

In this retrospective study based on 140 esotropic and 51 exotropic patients, the factors influencing successful outcome and response to strabismus surgery were investigated. Thirteen independent variables were chosen. The pre-operative deviation was found to be the only discriminant factor for early and late successful surgical outcomes in esotropic patients. For exotropic patients the visual acuity of the left eye was the discriminant factor for early successful surgical outcome. In esotropic ...

Malgre une bonne stereopsie, il se peut qu'avec le temps, une exotropie intermittente corrigee chirurgicalement se mette a devier progressivement vers l'exterieur. Nous avons voulu etablir les facteurs precoces qui influent sur le succes de la correction chirurgicale. L'echantillon sur lequel nous avons travaille etait constitue de patients consecutifs dont l'âge variait entre 1,9 an et 76 ans, operes pour une exotropie intermittente. Leur etat sensoriel a ete evalue au moyen du stereotest Titmu...

• Based on analyses in a series of 116 patients, we found that the response to strabismus surgery (degrees of change of ocular alignment per millimeter of rectus recession) correlated significantly with the preoperative deviation for esotropic and exotropic patients. The prediction of response to strabismus surgery was not improved significantly with the inclusion of axial length, age, and/or preoperative refractive error beyond the prediction provided with use of only the preoperative deviation...

Background: Impaired stereopsis very often limits career options for patients with binocular vision disorders. Eyesight requirements for some occupations like police officers and firefighters usually include perfect visual acuity. In Poland, candidates for these professions must also demonstrate perfect stereopsis. The presented case study aims to demonstrate that vision therapy (VT1) mixed with new technologies may be an effective treatment for young adults who do not meet the chosen occupation...

Purpose. To evaluate whether clinical measures of postoperative binocular functions could predict the long-term stability of postoperative ocular alignment in children with intermittent exotropia. Methods. A retrospective study was performed in thirty-nine children (median: 7 years) who have been surgically treated from intermittent exotropia without overcorrection (less than 10 prism diopters [pd] of exodeviation at 1 month postoperatively). Angles of deviation and binocular functions were meas...

Abstract Purpose To observe the change in horizontal smooth pursuit in patients with intermittent exotropia before and after strabismus surgery. Methods The smooth pursuit of patients with intermittent exotropia was recorded using a video eye-tracker before and 1 week, and 1, 3, and 6 months after strabismus surgery. Subjects were asked to track a step-ramp target moving at ±6.1°/sec horizontally as accurately as possible under binocular viewing. The differences in gain (eye velocity divided by ...

To compare the long-term surgical outcomes between bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus plication (RP) in intermittent exotropia. Children who underwent BLR or RP for basic type intermittent exotropia between 2015 and 2016 with a minimum follow-up period of 2 years were retrospectively reviewed. Surgical outcomes were classified based on postoperative angle of deviation as follows: success (esodeviation ≤ 5 prism diopters [PD] to exodevia...

Intermittent exotropia (X(T)) is one of the most common form of strabismus with surgery being the mainstay of treatment. The main goal of surgery is to preserve binocular vision and stereopsis and to prevent its further loss. The decision to operate is mainly based on four aspects: increasing angle of exodeviation, deteriorating control of X(T), decrease in stereopsis for near or distance and quality of life. Bilateral lateral rectus muscle recession and unilateral lateral rectus recession with ...
