Filter by:Thirty-four subjects with constant exotropia were included. Two independent ophthalmologists measured the angle of ocular deviation using alternate prism cover test (APCT). The video files and data with the changes in ocular deviation during the alternate cover test were obtained using video-oculography (VOG). To verify the accuracy of VOG, Investigator compared the value obtained using VOG and the angle of a rotating model eye, and subsequently made a new linear equation using these data. The calculated values obtained using VOG were compared with those obtained using APCT to determine the diagnostic accuracy of VOG.
The main objectives of this randomized trial comparing overminus lens treatment to non-overminus (spectacles without overminus or spectacles with plano lenses) are to determine: - The long-term on-treatment effect of overminus treatment on distance intermittent exotropia (IXT) control score. - The off-treatment effect of overminus treatment on distance IXT control score (following weaning and 3 months off treatment).
This study is to investigate protective effect of biodegradable collagen implant in scleral showing after lateral rectus recession in patients with exotropia.
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.
The objective of this short-term, pilot randomized trial comparing 2.50 diopters (D) overminus lens treatment vs. non-overminus (spectacles without overminus or no spectacles) in children with intermittent exotropia (IXT) 3 to <7 years of age is to determine whether to proceed to a full-scale, longer-term randomized trial.
This study was conducted to evaluate results of slanted recession of the lateral rectus muscle for intermittent exotropia with convergence weakness
Two different treatments were given to large angle horizontal strabismus (eso and exotropia) adult patients who agree to participate of the study. Inform consents were required for participants. Group 1 (12 patients) received conventional recess-resect surgery plus intraoperative injection of botulinum toxin A (5U). Group 2 (11 patients) received only conventional recess-resect surgery. The patients were randomly located in one of the groups. The angles of horizontal deviation were compared between the groups before and six months after treatment.
The purpose of this study is to evaluate the effectiveness of bilateral lateral rectus muscle recession versus unilateral lateral rectus recession with medial rectus resection procedures for the treatment of basic type and pseudo divergence excess type intermittent exotropia.
The present study is being conducted to assess the natural history of intermittent exotropia and to establish the effectiveness of occlusion in its treatment. Study Objectives: - To determine the effectiveness of occlusion for the treatment of intermittent exotropia among patients aged 3 to < 11 years who have baseline near stereoacuity of 400 arcsec or better by Preschool Randot stereotest - To determine the natural history of intermittent exotropia among patients aged 3 to < 11 years who have baseline near stereoacuity of 400 arcsec or better by Preschool Randot stereotest
