Abstract
Purpose: To evaluate factors associated with the direction of horizontal deviation in the sensory strabismus of patients with unilateral organic amblyopia. Methods: The medical charts of 53 patients who had been diagnosed with sensory strabismus between 2000 and 2009 were reviewed retrospectively. The underlying ocular disease, time of onset and the duration of vision impairment, refractive error and axial length of the fixing eye, and the direction and angle of deviation were analyzed to determine the distribution of underlying diseases and any factors relevant to determining the direction of the horizontal deviation. Results: Congenital cataracts were the most common underlying disease, found in 33 patients, followed by acquired cataracts, optic nerve disorders, retinal detachment, glaucoma and lens subluxation. Among the 50 patients with horizontal strabismus, 11 had esotropia and 39 had exotropia. The incidence of esotropia was significantly higher when the fixing eye had hyperopia or emmetropia, than when the eye was myopic. Age of onset of vision deterioration and at diagnosis of sensory strabismus, and the axial length of the fixing eye had no relationship to the direction of horizontal deviation. In addition, the duration of visual impairment had no sig nificant relationship with the direction or extent of horizontal deviation. Conclusions: The most common cause of sensory strabismus was congenital cataracts and the most frequent type of strabismus was exotropia. With respect to the direction of horizontal strabismus, esotropia occurred significantly more often when the refractive error of the fixing eye was hyperopia or emmetropia than when the fixing eye was myopic.

Purpose: To study the clinical characteristics of pediatric sensory strabismus in Korean children. Methods: A retrospective analysis was performed on 71 patients with the diagnosis of sensory strabismus before the age of 16 years. Patients with strabismic amblyopia or anisometropic amblyopia were excluded from consideration. The age at onset of vision loss, diagnosis, type of strabismus, deviated angle, etiologic factors leading to vision loss, and visual acuity of the deviated eye were recorded...
Purpose: To evaluate the factors influencing the direction of sensory strabismus and the consequent surgical outcomes. Methods: We retrospectively reviewed the medical records of 150 sensory strabismus patients who had undergone surgery. Consisting of 38 esotropes and 112 exotropes. Parameters considered were the cause of vision loss, the age at vision loss, the refractive error of the sound eye, the interorbital distance in the posteroanterior view of the orbit, the deviation angle at postopera...

Abstract Purpose The purpose of this study is to identify the characteristics of strabismus that coexist with nanophthalmos and to report the results of strabismus surgery performed on these small eyes. Design Retrospective, consecutive, noncomparative interventional case series. Participants Fifteen bilateral nanophthalmic patients, of whom five underwent horizontal muscle surgery, were included in this study. Methods Chart review. The clinical examination included visual acuity assessments usi...

Purpose: We reviewed the clinical features and the treatment results of sensory heterotropia with the purpose of finding etiologic causes, factors influencing the the direction of deviation, and characterisitics of sensory deviations subsequent to cataract. Methods: The charts of 134 patients diagnosed as sensory heterotropia in Chonbuk national university hospital between 1994 and 2001 were reviwed retrospectively. Visual acuity, the deviation in primary gaze, refractive error, the onset of vis...
Purpose: This study was carried out for the clinical analysis of deviation axis of sensory strabismus Methods: We retrospectively reviewed the medical records of 100 patients who had been diagnosed with sensory strabismus and undergone surgery. Etiology, age at onset of vision loss, duration of vision loss, refraction in sound eye, angle of deviation according to sensory esotropia and exotropia were analyzed. Results: The most common etiology was corneal opacity which occurred in 17 patients (17...

Purpose: The type of horizontal strabismus from loss or impairment of vision is thought to depend on patient age at the time of vision loss. Association between the age at onset of vision loss and development of esotropia vs exotropia will be determined. Methods: Patients with a diagnosis of sensory strabismus and visual acuity of 20/40 or poorer were reviewed as well as patients with diagnoses consistent with the development of sensory strabismus. Parameters considered were age at onset of visi...

Abstract Objective To evaluate the different modalities of treatment of the strabismus related to infantile glaucoma, its complications, and results. Methods The clinical history of 7 patients with infantile glaucoma which required strabismus surgical treatment were analyzed. Age at onset of glaucoma, type of glaucoma, glaucoma surgeries, type of strabismus, strabismus surgical treatment and postoperative results were studied. Results Four patients required strabismus surgery, two were treated w...

We present the first case series of patients with no systemic neurologic disease who experienced a spontaneous conversion from an initial exotropia to a sensory esotropia in the absence of strabismus surgery or chemodenervation. The patients in this series all were exotropic in the first 2 years of life, with the strabismic eye having decreased vision due to unilateral ocular pathology. All patients demonstrated spontaneous conversion to esotropia between 4 and 8 years of age and thereafter clin...

Importance Educating parents to recognize signs of eye disease and consult a healthcare professional is critical to timely diagnosis, intervention and outcomes. Background We evaluate the effectiveness of an eye-health information pamphlet on parents' level of concern and help-seeking intention should they hypothetically observe leukocoria or strabismus in their child. Design Double-blind, randomized controlled trial conducted at a metropolitan antenatal outpatient clinic. Participants In total,...

Background and Objectives: Early diagnosis and intervention is essential to achieve optimal outcomes for most pediatric eye diseases. Educating parents/caregivers to recognize early signs of disease and consult a healthcare professional is critical to achieving this aim. We evaluate the effectiveness of an eye-health information pamphlet on parents level of concern and their help-seeking intention if they observed leukocoria or strabismus. Methods: Pregnant women attending a metropolitan antenat...

Purpose: To assess clinical features of sensory exotropia with distant-near disparity, surgical outcome, and compare according to amount of medical rectus resection. Methods: Authors retrospectively reviewed medical records of patients of sensory exotropia with follow-up over 6 months. We defined patients with over 10 prism diopter (PD) disparity as distant-near disparity sensory exotropia (DND-XT) and without disparity as basic sensory exotropia (B-XT). First, we analyzed and compared data of v...
