NCT06650735
The goal of this clinical trial is to compare the efficacy of bilateral lateral rectus recession and bilateral primary medial rectus resection in basic type intermittent exotropia Participants will be randomized into two groups: bilateral lateral rectus (BLR) recession and bilateral medial rectus (BMR) resection groups then followed up in the clinic for 6 months to compare motor alignment and sensory functions
NCT04152122
A novel dynamic random-dot stereopsis test that included motion + disparity (MD), motion (M), and disparity (D), in which the disparity cues range from 200 to 1200 arc-seconds was used. The characteristics of preoperative dynamic stereopsis in 83 intermittent exotropia patients and its associations with clinical features were analysed, and the prognosis was followed up on the 1st day and 2nd, 6th and 12nd months postoperatively.
NCT03952702
In this prospective study, entitled "The Long-Term Efficacy of Overminus Lens Therapy in Intermittent Exotropia",the investigators examined the long-term impact of overminus lenses on the management of intermittent exotropia (IXT), treatment effect after overminus treatment has been discontinued and also investigated if overminus lenses cause myopia in long-term.
NCT03641040
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.
NCT03321838
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.
NCT02223650
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.
NCT02699580
This study is to investigate protective effect of biodegradable collagen implant in scleral showing after lateral rectus recession in patients with exotropia.
NCT02131792
This study was conducted to evaluate results of slanted recession of the lateral rectus muscle for intermittent exotropia with convergence weakness
