Active clinical trials for "Esotropia"

To test the hypothesis that correction with bifocal spectacle lenses rather than single-vision lenses will slow the progression of myopia in children with near-point esophoria. The primary outcome variable is cycloplegic refraction as measured with an automated refractor. Axial length is measured with ultrasound in order to test the corollary hypothesis that use of bifocals will slow ocular growth in these myopic children. We will also examine the amount of close work performed by subjects and the degree of parental myopia as factors that may influence myopia progression.

This study seeks to determine if bupivacaine injection of eye muscles can make them stronger and stiffer, and thereby correct the position of eyes that are turned in or mis-aligned, a condition generally termed strabismus. It seeks further to find out the different effects of various concentrations or formulations of bupivacaine, and whether addition of Botox to other eye muscles can add to the effect of bupivacaine and enhance the correction of strabismus.

In this study, the surgical outcomes of lateral rectus plication and resection techniques on patients with residual esotropia will be compared. Methods: In this randomized clinical trial, a total of 57 patients with residual esotropia (31 females and 26 males) who were candidate for lateral rectus resection are going to be included and randomized into plication and resection groups. The inclusion criteria will be residual esotropia after uni- or bilateral medial rectus recession, or unilateral recession and resection (R&R). Subjects with a history of prematurity, lack of central fixation, extraocular muscle palsy, systemic, ocular disorders, follow up less than three months will be excluded. A comprehensive ophthalmic examinations are going to be conducted preoperatively and at 1, 3 and 6 months' follow-ups. Surgical success rate will be considered in cases with a postoperative eso- or exotropia ≤10pd.

Adult patients requiring surgery for esotropia will be randomized to surgery under topical anesthesia or sub-Tenon's anesthesia. Amount of surgery required with the two anesthetic procedures will be compared. Motor and sensory outcome of the two treatment groups will also be compared.

The objective of this prospective study is the treatment of esotropia by prescribing the full precise optical correction of refractive errors in children up to 3 years old.

The strabismus impacts binocular visual acuity and stereoscopy. Thus, driving capacities of patients with strabismus may be reduced. The goal of this work is to study the possible amelioration of driving ability after strabismus surgery and to compare the driving capacities of patients with strabismus to a normal population; Patients will be tested before and after strabismus surgery using a driving simulator, binocular visual field and binocular visual acuity.

To investigate changes in refractive errors and evaluate clinical outcomes of strabismus surgery in patients with both amblyopia and partially refractive esotropia (PAET).Amblyopic patients with PAET were enrolled. Non-amblyopic patients with full refractive accommodative esotropia (RAET) were included in the study as a control group. Preoperative and postoperative best corrected visual acuity (BCVA), spherical equivalent (SE), astigmatism, stereoacuity and deviations at near and distance were evaluated and statistically compared in the patient group. The mean BCVA, SE, astigmatism were compared between the patient and the control groups.

To observe the early course of congenital esotropia, a form of childhood strabismus. This will determine the probability of spontaneous resolution. Researchers then will try to correlate this finding with various aspects of the esotropia such as the (1) size of the esotropia, (2) variability, and (3) presence of hyperopia. This information will be used to determine the feasibility of conducting a clinical trial to assess the benefit of early surgery for congenital esotropia and, if feasible, to refine eligibility criteria for the trial.

The goal of this study is to determine whether corrective surgery done earlier than the current standard can better improve the visual and eye movement deficits in children with infantile esotropia (crossed eyes in infancy).

Infantile esotropia is corrected in most cases by bilateral recession of the medial rectus muscles (BR) or by unilateral recession of the medial rectus muscle and resection of the lateral rectus muscle (RR). We compared the outcome of these techniques in a randomized prospective study.
