Filter by:Strabismus is one of the most frequent ocular problems among developmentally normal children. The prevalence of strabismus varies among different regions, ranging from 0.06% in Japan to 5.65% in China. Exotropia is reported to be the most prevalent type of deviation in many of these studies. About 48-92% of the exotropic patients have intermittent exotropia (IXT). Jenkins reported that the prevalence of exodeviation was higher in countries near the Equator. Its prevalence is also higher in subequatorial Africa, the Middle East, and East Asia (where there is plenty of sunshine) in comparison to the USA and Central Europe. Intermittent exotropia is a disorder of binocular eye movement control, where one eye intermittently turns outward. The outward deviation is greatest and likely occurs at far distances viewing, when the oculomotor convergence effort is weakest, and occurs frequently when the patient is under stress, tired, ill, or in particular test situations. X(T) can also occur at near as convergence insufficiency.
The aim of this study is to evaluate the techniques of combined lateral rectus muscle recession with hang back and combined lateral rectus muscle recession with z-tenotomy in correcting large-angle exotropia.
study aiming to evaluate all children presented to strabismus clinic in ophthalmology department at sohag university hospital with divergent squint (exotropia) and to record surgical outcome of those who underwent strabismus surgery in our hospital
Effectiveness of office based vergence/accommodative therapy for the treatment of intermittent exotropia is investigated through a randomized clinical trial
It is prospective cohort study to compare ( the surgical outcome) the motor and sensory outcome of early surgery (≤5 years of age) and late surgery ( ≥ 7 years of age) for intermittent exotropia.
Purpose: To determine the surgical outcomes of the plication technique in comparison with the resection method on exotropic patients. Methods: In this randomized clinical trial, a total of 52 exotropic patients (female, 51.9%) who are candidate for medial rectus strengthening will be randomly classified into plication (n=24) and resection (n=28) groups. The comprehensive visual and ocular examinations will be performed on all study subjects and they will be followed- up for three months postoperatively. Plication technique is the same as resection up to muscle suturing, in the next step, the sutures are passed through 2 scleral bites at 1 mm anterior to the muscle insertion, then the muscle was folded toward inside or outside by pulling and joining the sutures.
Intermittent exotropia is the most common type of exotropia in children. Treatment options are surgical and non surgical. Nonsurgical management include Correction of refractive errors, Active orthoptic treatments, Prisms and Occlusion therapy. Benefits of patch therapy are limiting suppression, reducing the frequency and amplitude of the deviation, changing the nature of the deviation (from constant to intermittent exotropia or from intermittent exotropia to exophoria), however, there is a concern that occlusion of the eyes may cause fusion failure and worsen deviation control. According to a few number of studies and controversy among the results of investigations, the investigators designed this randomized clinical trial study to determine the effect of partial patch therapy on the deviation control of children with intermittent exotropia.
