View clinical trials related to Intermittent Exotropia.
Filter by:In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. This situation adversely affects children's psychosocial development and creates worries about personal relationships and work life in their future lives. Patients' hesitant attitudes towards surgical treatment led to the out-of-surgery techniques such as exercise therapy. No studies have been found in the literature on the efficancy of the intermittent exotropia treatments with oculo-motor exercises. In our study, it was aimed to investigate the effects of oculo-motor exercises on intermittent exotropia in children.
Fifteen subjects with intermittent exotropia were included. The subjects were asked to fixate on a black-on-white optotype at 1 m, which subtended a visual angle of 50 min of arc, equating to a Snellen optotype of 20/200. The video files and data about ocular deviations were obtained using VOG with alternate cover test. Investigators analyzed angles of ocular deviations in dominant and non-dominant eyes, compared with values of VOG and deviation angles of the alternative prism cover test.
This pilot study is designed specifically to determine the short-term effect of OBVAT on intermittent exotropia in terms of 4 key areas (Standardizing reported outcomes of surgery for intermittent exotropia): control score, alignment, near stereoacuity and quality of life score. Result of this pilot study will be used to determine whether a full-scale RCT should be conducted to evaluate the short and long term effectiveness of OBVAT.
This study presents an opportunity to understand a novel, previously unreported controlled intermittent alternate occlusion (CIAO) therapy glasses, which may improve the control of Intermittent exotropia (IXT).
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).
To determine the effectiveness of alternate occlusion therapy for the treatment of IXT among patients aged 3 to < 11 years old.
- Background and study aims : The investigators conducted this study to compare the movement of extraocular muscle after two types of recession surgery with non-invasive tool called AS-OCT. - Who can participate? patients who will undergo two types (conventional method and hang-back method) of typical bilateral lateral rectus recession surgery for correcting intermittent exotropia - What does the study involve? Volunteers will attend a clinic for four visits over three months. They will undergo AS-OCT at every visits during follow up period. AS-OCT is non-invasive test to evaluate operation site. The test only requires their cooperation when they undergo AS-OCT. - What are the possible benefits and risks of participating? This is non-invasive test for your postoperative follow up. Therefore, there will be no risks about this test. - Where is the study run from? Samsung Medical Center - When is the study starting and how long is it expected to run for? From April 2015 to Dec 2015

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
