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 analy...

BACKGROUND: This survey was performed to determine the effect of unilateral lateral rectus recession in treatment of moderate angle intermittent exotropia. However, this type of operation and its long term results in patients with moderate angle exotropia have not yet been studied in Iran. METHODS: Forty patients with basic type intermittent exotropia with moderate angle deviation (25-30∆D) wer...

We congratulate Yu et al. for their successful results where they evaluated the pattern distribution and the changes of strabismus surgery in pediatric population [1]. The authors observed that surgery for childhood exotropia was more common than surgery for esotropia in China and they stated that strabismus type and onset age were found to be associated with binocular function for subjects wit...

We report a case of acute comitant esotropia in a child with a cerebellar tumor. A 3-year-old boy was referred for management of a 9 month history of acute acquired comitant esotropia. On first presentation, the patient's angle of esodeviation was 50 prism-diopters (PD) at distance and near fixation without any lateral incomitance. The cycloplegic refraction revealed +0.75 diopters in both eyes...

PURPOSE To compare the outcomes of unilateral lateral rectus recession between the first operation and second operation for exotropia. METHODS Thirty-two patients who underwent unilateral lateral rectus recession for exotropia of 15 to 20 prism diopters (PD) were investigated. The follow-up period was at least 6 months. We classified 17 patients without a surgical history for exotropia (first...

Background: Strabismus surgery aims to improve the ocular alignment of visual axis & cosmetic appearance studied cases with strabismus. The most common functional benefits are restoration binocular vision, elimination diplopia compensatory head posture.In large-angle exotropia, many surgical methods have been performed, bilateral lateral rectus recession, medial resection recession frequently u...

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 st...

Strabismus represents a complex oculomotor disorder characterized by the deviation of one or both eyes and poor vision. A more sophisticated understanding of the genetic liability of strabismus is required to guide searches for associated molecular variants. In this classical twin study of 1,462 twin pairs, we examined the relative influence of genes and environment in comitant strabismus, and ...

purpose: to compare the results of conventional hang-back technique (chbt) with that of anchored hang-back technique (ahbt) for bilateral lateral rectus (lr) recession in patients with exotropia. methods: in this randomized clinical trial, 60 patients underwent chbt (group 1) or ahbt (group 2) for lr recession (30 patients in each group). preoperative and postoperative deviation, age, sex, the ...
