Duane retraction syndrome (DRS) is a congenital eye movement anomaly characterized by variable horizontal duction deficits, with narrowing of the palpebral fissure and globe retraction on attempted adduction, occasionally accompanied by upshoot or down-shoot. The etiopathogenesis of this condition can be explained by a spectrum of mechanical, innervational, neurologic and genetic abnormalities occurring independently or which influence each other giving rise to patterns of clinical presentations along with a complex set of ocular and systemic anomalies...

PURPOSE: This study aims to describe and compare modified hang-back recession with the conventional hang-back recession in large angle comitant exotropia (XT). METHODS: A prospective, interventional, double-blinded, randomized study on adult patients (>18 years) undergoing single eye recession-resection for large angle (>30 prism diopters) constant comitant XT was conducted between January 2011 and December 2015. Patients in Group A underwent modified hang-back lateral rectus recession with adjustable knot while in Group B underwent conventional hang-back recession with an adjustable knot...

In subjects with alternating strabismus either eye can be used to saccade to visual targets. The brain must calculate the correct vector for each saccade, which will depend on the eye chosen to make it. The superior colliculus, a major midbrain center for saccade generation, was examined to determine if the maps serving each eye were shifted to compensate for strabismus.Alternating exotropia was induced in two male macaques at age one month by sectioning the tendons of the medial recti. Once the animals grew to maturity, they were trained to fixate targets with either eye...

PURPOSE: To characterize current practice preferences of pediatric ophthalmologists in the management of amblyopia and whether these are influenced by demographic variables. METHODS: A 10-question survey was distributed to all pediatric ophthalmologists and fellows attending the Annual Joseph H. Calhoun Pediatric Ophthalmology Forum at Wills Eye Hospital in 2016. The questionnaire consisted of demographic information and clinical management of amblyopia using clinical scenarios commonly encountered in pediatric ophthalmology practice...

PURPOSE: To investigate the development pattern and related factors of postoperative re-drift in infantile esotropia. METHODS: A total of 112 patients with infantile esotropia who underwent surgery before 3 years of age were included. Surgical outcomes were divided into (1) consecutive exotropia: more than 8 prism diopters (PD) of exodeviation; (2) recurrent esotropia: more than 8 PD of esodeviation; and (3) monofixation syndrome: maintenance of deviations within 8 PD...

PURPOSE: To determine the efficacy of a biodegradable Ologen (Aeon Astron Europe BV, Leiden, The Netherlands) collagen matrix in reducing the blue color change due to exposed thinned sclera after strabismus surgery. METHODS: Fourteen patients with intermittent exotropia undergoing symmetric bilateral lateral rectus recession surgery were included in this prospective, randomized, paired-eye controlled study. In each patient, Ologen was implanted at the original rectus insertion site in one randomly selected eye; the other eye underwent conventional surgery...

PURPOSE: To compare surgical outcomes according to the distance between the preplaced suture and the muscle insertion in lateral rectus (LR) recession for exotropia. METHODS: We retrospectively reviewed 64 patients who had undergone unilateral LR recession by one right-handed surgeon and divided the patients into 2 groups: right LR recession (R group, 26 patients) and left LR recession (L group, 38 patients). In the R group, the preplaced suture was behind the hook, far from the insertion; in the L group, the suture was in front of the hook, near the insertion...

PURPOSE: To compare adjustable sutures versus nonadjustable sutures for intermittent exotropia. METHODS: In this randomized prospective interventional study, 40 adult patients with intermittent exotropia were randomly divided into 2 equal groups. Both groups underwent bilateral lateral rectus recession. In group A, adjustable suture recession was performed, and in group B, nonadjustable suture recession was performed. Patients were followed up for 6 months and outcome measures were residual deviation, binocular status, and need for resurgery...

Purpose: The purpose of this review was to examine the efficacy of botulinum toxin in the treatment of infantile esotropia and to evaluate the average response of BT and its complication rates. Methods: A research was performed in the Latin American and Caribbean Literature on Health Sciences (LILACS), MEDLINE, and Cochrane Central Register of Controlled Trial (CENTRAL). The database was searched between December 28, 2016 and January 30, 2017. The selection was restricted to articles published in English, Spanish, or Portuguese...

A 17-year-old boy presented with a large exotropia with both eyes fixed in an abduction and upgaze, pupillary involvement since childhood. He had mild optic nerve hypoplasia in the right eye and situs inversus of the retinal vessels in the left optic disc. His ocular motility showed restriction of eye movements in all gazes. He was diagnosed with congenital fibrosis of extraocular muscles, type 2 (CFEOM2) and operated upon in a staged procedure with a satisfactory eye alignment using hang-back sutures in one eye and periosteal fixation in the other...

PURPOSE: To compare the accuracy of widefield ultrasound biomicroscopy (UBM) with mechanical intraoperative measurements of the distance between rectus muscle insertions and the corneal limbus in strabismus reoperations. METHODS: Subjects with a history of horizontal rectus muscle surgery who required further surgery on horizontal rectus muscle(s) were recruited prospectively. All widefield UBM measurements were carried out under topical anesthesia using a 50 MHz linear probe without immersion cup and external caliper...

BACKGROUND: To present the data of a series of patients with synergistic divergence, to propose a different modality of surgical correction and to perform a literature review of such a rare entity. METHODS: A retrospective study was performed on all patients who presented with unilateral or bilateral synergistic divergence to the Ophthalmology Department, Cairo University, during the period from January 2007 to July 2016. The demographic data, the results of sensorimotor examination, the surgical procedures performed and the ophthalmological as well as the systemic findings of all patients were collected and tabulated...

PURPOSE: To quantify refractive changes following horizontal lateral rectus recession and medial rectus resection surgery and to investigate the causes of these changes. METHODS: The medical records of patients who underwent unilateral horizontal lateral rectus recession and medial rectus resection for exotropia by a single surgeon over a period of 14 years were reviewed retrospectively. Using vector analysis, refractive changes in operated eyes (cases) were compared to changes in the sound eyes (controls)...

PURPOSE: To evaluate the surgical results of medial rectus (MR) muscle advancement with or without recession of the antagonist muscle for consecutive exotropia. METHODS: Medical records of patients with consecutive exotropia (n = 27) were retrospectively reviewed. All patients received one-eye surgery with MR advancement, lateral rectus (LR) recession, or combined surgery. The pre- and post-operative angle of deviation was recorded. Characteristics were compared between groups...

BACKGROUND/PURPOSE: The concept of adjustable suture has been developed in strabismus surgeries for nearly four decades. This technique is not yet universally embraced by strabismus surgeons, especially in pediatric patients. The aim of this study is to describe and evaluate the application of the adjustable suture with pull-string technique in pediatric patients. METHODS: A retrospective medical record review was conducted for patients aged 18 years and under who received adjustable suture strabismus surgery using short tag sliding noose with pull-string technique...

PURPOSE: To evaluate the effect of improvement in the control grade of intermittent exotropia using part-time occlusion therapy on the final postoperative outcome. METHODS: Control of intermittent exotropia was graded as good, fair, or poor in 89 consecutive patients with intermittent exotropia during their first visit. The patients were reevaluated after part-time preoperative occlusion therapy and divided into two groups (improvement and no improvement) according to whether they showed improvement in control grade...
