Active clinical trials for "Amblyopia"

This was a randomized, masked, controlled study of the effect of a virtual reality, binocular, 3-dimensional video game on visual acuity and stereopsis in adult patients with amblyopia. The trial has been halted as of June 2016 and will not be evaluating any new subjects for enrollment.

This study is designed to evaluate the effectiveness of a novel amblyopia treatment - Intermittent occlusion therapy (IO-therapy) glasses (AmblyzTM) in treating severe amblyopia. Children ages 3 to 8 years with severe amblyopia (visual acuity of 20/100 to 20/400 in the amblyopic eye) will be enrolled and randomized into two groups: 1) standard 6-hour patching group or 2) 12-hour IO-therapy glasses group. The study also observe the effectiveness of IO-therapy glasses on two types of difficult amblyopia: deprivation amblyopia associated with congenital or developmental cataract, and myopic anisometropic amblyopia.

This study is comparing the effectiveness of patching combined with active vision therapy plus near activities versus patching combined with control vision therapy plus near activities for moderate amblyopia (20/40-20/100) in 7 to <13 year olds. The primary outcome measure is the proportion of patients with visual acuity of 20/25 or better in the amblyopic eye at the 17-week masked exam. These patients will be considered treatment responders. The primary analysis will consist of a comparison between the 2 treatment groups of the proportion of treatment responders with adjustment for baseline visual acuity. Secondary outcomes are stereoacuity at the 17-week masked exam, mean improvement in visual acuity at the 17-week masked exam, and rate of improvement of visual acuity.

A prospective interventional study is expected to be conducted, to test a possible new treatment for amblyopia (lazy eye syndrome). Bilateral transcranial direct current stimulation (tDCS) is a type of noninvasive brain stimulation, which may help in visual function recovery of adult patients with amblyopia. This pilot study will test the feasibility of said therapy, along with the short term effects of bilateral tDCS in visual function.

Electronic eyeglasses, Amblyz™glasses, are a new medical device designed to treat amblyopia, which intermittently become opaque and provide effective occlusion for 50% of the time they are worn. A non-randomized study reported that Amblyz glasses yield an improvement in the amblyopic eye and offer an alternative effective treatment. We are unaware of any randomized clinical trial reports of response to AmblyzTM glasses treatment of amblyopia. Our hypothesis: Amblyz™glasses can improve visual acuity of the amblyopic eye as effective as traditional patching treatment. The primary objective is to determine if AmblyzTM equally treats moderate amblyopia as the standard 2-hour patching treatment and AmblyzTM equally treats severe amblyopia as the standard 6-hour patching treatment. This study is designed to evaluate the effectiveness of a novel amblyopia treatment, AmblyzTM glasses, in treating amblyopia. Moderate amblyopia: Children ages 3 to <8 years with visual acuity of 20/40 to 20/80 in the amblyopic eye will be enrolled and randomized into two groups: 4-hour AmblyzTM glasses treatment group and standard 2-hour patching control group. Severe amblyopia: Children ages 3 to <8 years with visual acuity of 20/100 to 20/400 in the amblyopic eye will be enrolled and randomized into two groups: 12-hour AmblyzTM glasses treatment group and standard 6-hour patching control group.

This study is designed to evaluate the effectiveness of treatment of residual amblyopia in children ages 3 to < 10 years with visual acuity of 20/32 to 20/63 in the amblyopic eye. The study is a randomized clinical trial comparing intensive treatment (42 hours per week of patching plus daily atropine) with a control group that will have rapid weaning of existing treatment followed by spectacle correction only (if needed). The primary objective is to determine if this intensive treatment will improve visual acuity in patients with residual amblyopia. The primary outcome assessment is amblyopic eye visual acuity at 10 weeks. The primary analytic approach for the amblyopic eye acuity will be a treatment group comparison of the proportion of patients with at least two lines of visual acuity improvement.

This study is designed to answer the question: What if the Intermittent Occlusion (IO-therapy) glasses were prescribed all day (12-hours) in which the total time of treatment only took 4 weeks instead of the current treatment time (4 hours) in which it takes 12 weeks? Children aged 3- to 8-years with untreated moderate unilateral amblyopia will be enrolled and randomized into 2 groups: 1) Intense 12-hour IO-therapy Group for 4 weeks treatment; or 2) Standard 4-hour IO-therapy glasses Group for 12 weeks treatment.

The objective of the study is to demonstrate the safety and efficacy of Luminopia One in amblyopia patients with amblyopia associated with anisometropia and/or with mild strabismus.

This study evaluates the effectiveness of the monocular treatment with action video-games in comparison with the occlusion therapy alone in amblyopic patients, and the satisfaction with the different evaluated treatments.

The study will evaluate the effect of Reviview™, a dichoptic video display device for administrating a novel treatment protocol for Amblyopia (lazy eye) in kids. The effect of the treatment will be measured by the change from baseline in Visual acuity and in Stereoscopic Vision; and to assess the ease of use of and compliance by the patients.
